Method to create colloidal diamonds developed

The colloidal diamond has been a dream of researchers since the 1990s. These structures — stable, self-assembled formations of miniscule materials — have the potential to make light waves as useful as electrons in computing, and hold promise for a host of other applications. But while the idea of colloidal diamonds was developed decades ago, no one was able to reliably produce the structures. Until now.

Researchers led by David Pine, professor of chemical and biomolecular engineering at the NYU Tandon School of Engineering and professor of physics at NYU, have devised a new process for the reliable self-assembly of colloids in a diamond formation that could lead to cheap, scalable fabrication of such structures. The discovery, detailed in “Colloidal Diamond,” appearing in the September 24 issue of Nature, could open the door to highly efficient optical circuits leading to advances in optical computers and lasers, light filters that are more reliable and cheaper to produce than ever before, and much more.

Pine and his colleagues, including lead author Mingxin He, a postdoctoral researcher in the Department of Physics at NYU, and corresponding author Stefano Sacanna, associate professor of chemistry at NYU, have been studying colloids and the possible ways they can be structured for decades. These materials, made up of spheres hundreds of times smaller than the diameter of a human hair, can be arranged in different crystalline shapes depending on how the spheres are linked to one another. Each colloid attaches to another using strands of DNA glued to surfaces of the colloids that function as a kind of molecular Velcro. When colloids collide with each other in a liquid bath, the DNA snags and the colloids are linked. Depending on where the DNA is attached to the colloid, they can spontaneously create complex structures.

This process has been used to create strings of colloids and even colloids in a cubic formation. But these structures did not produce the Holy Grail of photonics — a band gap for visible light. Much as a semiconductor filters out electrons in a circuit, a band gap filters out certain wavelengths of light. Filtering light in this way can be reliably achieved by colloids if they are arranged in a diamond formation, a process deemed too difficult and expensive to perform at commercial scale.

“There’s been a great desire among engineers to make a diamond structure,” said Pine. “Most researchers had given up on it, to tell you the truth — we may be the only group in the world who is still working on this. So I think the publication of the paper will come as something of a surprise to the community.”

The investigators, including Etienne Ducrot, a former postdoc at NYU Tandon, now at the Centre de Recherche Paul Pascal — CNRS, Pessac, France; and Gi-Ra Yi of Sungkyunkwan University, Suwon, South Korea, discovered that they could use a steric interlock mechanism that would spontaneously produce the necessary staggered bonds to make this structure possible. When these pyramidal colloids approached each other, they linked in the necessary orientation to generate a diamond formation. Rather than going through the painstaking and expensive process of building these structures through the use of nanomachines, this mechanism allows the colloids to structure themselves without the need for outside interference. Furthermore, the diamond structures are stable, even when the liquid they form in is removed.

The discovery was made because He, a graduate student at NYU Tandon at the time, noticed an unusual feature of the colloids he was synthesizing in a pyramidal formation. He and his colleagues drew out all of the ways these structures could be linked. When they happened upon a particular interlinked structure, they realized they had hit upon the proper method. “After creating all these models, we saw immediately that we had created diamonds,” said He.

“Dr. Pine’s long-sought demonstration of the first self-assembled colloidal diamond lattices will unlock new research and development opportunities for important Department of Defense technologies which could benefit from 3D photonic crystals,” said Dr. Evan Runnerstrom, program manager, Army Research Office (ARO), an element of the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory.

He explained that potential future advances include applications for high-efficiency lasers with reduced weight and energy demands for precision sensors and directed energy systems; and precise control of light for 3D integrated photonic circuits or optical signature management.

“I am thrilled with this result because it wonderfully illustrates a central goal of ARO’s Materials Design Program — to support high-risk, high-reward research that unlocks bottom-up routes to creating extraordinary materials that were previously impossible to make.”

The team, which also includes John Gales, a graduate student in physics at NYU, and Zhe Gong, a postdoc at the University of Pennsylvania, formerly a graduate student in chemistry at NYU, are now focused on seeing how these colloidal diamonds can be used in a practical setting. They are already creating materials using their new structures that can filter out optical wavelengths in order to prove their usefulness in future technologies.

How to Create High-performance, Scalable Content Websites Using MACH Technologies

Websites are easy to build these days. There is an abundance of tools available that let you create websites in minutes. However, building websites that are fast, scalable, and flexible that deliver superior performance is a lot more complex than creating a simple website. This is especially true when developing content-heavy websites, such as a news site, knowledge-base platform, online magazine, communities, and so on.

In general, content-heavy websites are likely to have hundreds or even thousands of pages, with new content added every day. They may also attract high traffic as they act as a body of knowledge hosting not just text content but also other media resources such as research reports, interactive maps, videos, images, calculators for consumers, or other dynamic tools. Consequently, they require a structure that supports quick publishing and accommodates frequent changes in content models and functionalities. 

It requires meticulous planning, a well-planned architecture, and modern technologies to develop and maintain a massive website and ensure that it delivers super-fast performance for every interaction with its visitors. 

Adopting a MACH approach is one of the effective ways to implement this. MACH stands for microservices, API-first, cloud-native, and headless technologies. It promotes having an architecture where most components are scalable and pluggable, enabling continuous improvement and easy replacement of modules without impacting the performance of others. 

This article shows how you can harness the power of different MACH and serverless technologies to develop and maintain a high-performance content-heavy website.

Use APIs for Content Management, Content Delivery, and to Connect to Other Apps 

With the advent of new IoT technologies, companies now have more ways and channels to connect and engage with customers. However, the underlying technology needs to be robust and flexible enough to support the channels of today and tomorrow.

Content on most devices today can be powered by APIs. Therefore it makes sense to use an API-based headless content management system that provides content as a service. Such CMSs are backend-only, front-end-agnostic platforms, so you can attach any frontend to it and deliver content through APIs. They give developers full control over how the content needs to be presented and allow integration with third-party apps. 

Integrate Pluggable Apps With Microservices Architecture 

A microservices architecture is a modern, complex approach that brings together loosely coupled, independently deployable applications, making your application modular and agile. With this approach, it becomes easier to build, test, and deploy features or parts of your application. 

Each service in such a setup has an API to communicate with the rest and has its own database, making it truly decoupled. This separation ensures that changes or issues with one service don’t impact another, and can be replaced immediately without downtime. 

This approach works well for a content-heavy website. It complements the cloud or serverless setup by enabling different teams to innovate rapidly, have greater control over the technologies, manage release cycles, and eventually cut down the time to market. 

Fortunately, due to rapid evolution in the SaaS space, all the services you need for a content site have API-based alternatives that can quickly form your application’s foundation. 

Let’s look at some of the apps that you can seamlessly integrate with your applications:

Optimize Content Delivery With CDN Caching 

Your website server exists at one physical location. Content needs to travel the distance to be delivered at another location. The farther the requester, the longer it takes to deliver the content. For instance, if your web server is in New Jersey, visitors in San Francisco will get the content faster than the visitors in Sydney, Australia. 

To avoid this lag and make your content delivery blazing fast, consider using a content delivery network (CDN). A CDN has a lot of network servers scattered across the globe. These servers save cached copies of your website content and act as distributors for visitors requesting content from nearby locations. For instance, visitors from Sydney will get the content from a nearby server (e.g., Melbourne) instead of New Jersey. 

For a large, content-heavy website, having a CDN is highly recommended. It eases the load on the server, reduces latency, and cuts the wait time for your visitors considerably. It also helps to protect your site against Denial of Service (DoS) attacks, which have the potential to bring your site down.

Go With Serverless Infrastructure for Quick Scaling and Easy Management 

While a microservices architecture is much more flexible and scalable than a traditional or monolithic one, an app built using the former approach is no good if it uses a legacy infrastructure that is unable to scale efficiently. 

It makes much more business sense to move to serverless computing, where the cloud provider handles the infrastructure concerns, server space, scalability, etc. The provider is responsible for provisioning, scaling, and managing the infrastructure as needed, where you purchase backend service on a “pay-as-you-go” model. 

This serverless approach ensures that your developers can focus more on writing code and developing features for the application, and worry less about the underlying infrastructure or scalability. Such a model can help you cope with demand spikes of your content-heavy website and ensure high performance.

Choose Scalable Presentation or Frontend Tools

If you adopt MACH technologies for your website, you are most likely to use a headless content management system (CMS) to manage the content and deliver it to your web application via APIs. Using a headless CMS, the frontend (presentation layer) is separate from the CMS backend, making it possible to choose any front-end technology that suits your needs. 

When making this choice, it’s important to remember that your frontend needs to be flexible, scalable, and fast, to accommodate the future requirements that the rapid evolution in technology is likely to bring. 

Another viable option is adopting a JAMstack architecture. It’s a modern way of building websites that are fast, secure, and quickly scalable. Some of the popular JAMstack frameworks are Gatsby, Next.js, and Gridsome.

In conclusion 

By adopting a MACH and serverless architecture, each component of your website has a clearly-defined task, enabling better performance as a whole. The pluggable design allows you to replace components as the technology evolves, thereby future-proofing applications. And finally, the serverless infrastructure provides all the scalability and security you need for your application. With such a solid foundation, a content-heavy website of any scale can deliver peak performance.

Painless paper patch test for glucose levels uses microneedles

Patches seem to be all the rage these days. There are birth control patches, nicotine patches, and transdermal medicinal patches, just to name a few. Now, a team of researchers led by Beomjoon Kim at the Institute of Industrial Science, The University of Tokyo have developed a patch of needles connected to a paper sensor for diagnosing conditions such as prediabetes. Luckily, this patch doesn’t multiply the pain and discomfort of a single hypodermic needle. In fact, these microneedles are painless and biodegradable.

Researchers have been trying to develop a practical way to use microneedles — tiny needles less than 1 mm in length — for routine do-it-yourself medical monitoring. Microneedles are so short that they stay within the skin and do not make contact with any neurons, meaning that they cause no pain. Rather than extracting blood, they draw up fluid in the skin that contains most of the important biomarkers that blood tests look for. Several types of microneedles exist, but until now, making a practical device that quickly analyzes the fluid has proved elusive. “We have overcome this problem by developing a way to combine porous microneedles with paper-based sensors,” says Kim. “The result is low-cost, disposable, and does not require any additional instruments.”

To make the patch, the researchers first made the microneedles by pouring a melted mixture of a biodegradable polymer and salt into the cone-shaped cavities of a micro-mold while applying heat. Then they flipped the mold and needles upside down and placed them on top of a piece of paper, this time applying high pressure from above. The high pressure forced the mixture into the pores of the paper, securing the attachment and allowing fluid drawn through the needles to pass effortlessly into the paper. After removal from the mold, the needles were cooled in a solution that sucked out all the salt, leaving behind thousands of holes, or pores, which are what the fluid flows through on its way to the paper. The salt concentration was a key factor they needed to optimize, testing several concentrations of salt to determine how porous the microneedles should be. To finish the patch, they used double-sided tape to attach a paper glucose sensor onto the paper base of the needle array.

The team tested the patch on an agarose gel in which glucose had been dissolved. Fluid from the gel flowed from the gel into the porous microneedles, and from there into the paper and the sensor layer. The glucose concentration was accurately recorded as color changes in the paper.

The patches are disposable, biodegradable, and using them does not require any medical expertise or training. They are also biocompatible, meaning that there is no problem if any remain in the skin when the patch is removed.

“Of course, prediabetes testing is just one application of the technology,” says first author Hakjae Lee. “The paper-based sensor can vary depending on the biomarker you wish to monitor.”

After this success, the next step will be to test the practicality of the device with human participants and to develop configurations for monitoring other substances, and in turn, determining the presence of other conditions.

Trapping and controlling light at the interface of atomically thin nanomaterials

Light can partake in peculiar phenomena at the nanoscale. Exploring these phenomena can unlock sophisticated applications and provide useful insights into the interactions between light waves and other materials.

In a recent study, scientists at Cornell University propose a novel method by which nanoscale light can be manipulated and transported. These special modes of light transport are known to arise at finely tuned interfaces between slightly different nanomaterials. Minwoo Jung, lead researcher on this study, illustrates this concept through a simple analogy: “A floating tube has a hole in the middle, but a normal balloon doesn’t. No matter how you squeeze the round balloon, it cannot be reshaped like a donut-at least not without popping the balloon, re-knitting the rubber, and re-injecting the air. Thus, a tube and a balloon are distinct in their topology because they are not connected through a smooth deformation.”

Jung further explains that physicists have been interested in gluing two topologically distinct materials side by side so that one of them acts like a balloon and the other like a tube. This means that, at their interface, a process that connects these two materials must occur, much like the poking/popping/re-knitting/re-injecting from a balloon to a tube. Under the right conditions, this process can give rise to a strong channel for transmitting energy or information along the interface. Because this process can be applied to light (which acts as a carrier of energy or information), this branch of physics is called topological photonics.

Jung and his team combined the fascinating concept of topological photonics with an innovative technique that traps light in an atomically thin material. This method brought together two rapidly emerging fields in applied and fundamental physics: graphene nanolight and topological photonics. Jung says, “Graphene is a promising platform for storing and controlling nanoscale light and could be key in the development of on-chip and ultracompact nanophotonic devices, such as waveguides and cavities.”

The research team ran simulations involving a graphene sheet layered on a nanopatterned material that functions as a metagate. This honeycomb-like metagate consists of a solid layer of material with holes of different sizes, centered at the vertices of the hexagons. The varying radii of these holes affect the way in which the photons pass through the material. The scientists found that strategically “gluing” together two different metagates creates a topological effect that confines photons at their interface in a predictable, controllable manner.

Different choices of metagate designs demonstrate the dimensional hierarchy of the device’s topology. Specifically, depending on the metagate geometry, nanolight can be made to flow along one-dimensional edges of the topological interface or can be topologically stored at zero-dimensional (point-like) vertices. Moreover, the metagate allows for on-and-off electric switching of these waveguides or cavities. Such battery-operated topological effects can benefit the technological adoption of topological photonics in practical devices.

Jung’s team is optimistic that the synergistic combination of graphene nanolight and topological photonics will spur advances in relevant research areas, like optics, material sciences, and solid-state physics. Their graphene-based material system is simple, efficient, and suitable for nanophotonic applications: a step forward in harnessing the full potential of light.

A new tool for modeling the human gut microbiome

Several thousand strains of bacteria live in the human gut. Some of these are associated with disease, while others have beneficial effects on human health. Figuring out the precise role of each of these bacteria can be difficult, because many of them can’t be grown in lab studies using human tissue.

This difficulty is especially pronounced for species that cannot live in oxygen-rich environments. However, MIT biological and mechanical engineers have now designed a specialized device in which they can grow those oxygen-intolerant bacteria in tissue that replicates the lining of the colon, allowing them to survive for up to four days.

“We thought it was really important to contribute a tool to the community that could be used for this extreme case,” says Linda Griffith, the School of Engineering Professor of Teaching Innovation in MIT’s Department of Biological Engineering. “We showed that you can grow these very fastidious organisms, and we were able to study the effects they have on the human colon.”

Using this system, the researchers showed that they could grow a strain of bacteria called Faecalibacterium prausnitzii, which lives in the human gut and protects against inflammation. They also showed that these bacteria, which are often diminished in patients with Crohn’s disease, appear to exert many of their protective effects through the release of a fatty acid called butyrate.

Griffith and David Trumper, an MIT professor of mechanical engineering, are the senior authors of the study, which appears today in the journal Med. MIT postdocs Jianbo Zhang and Yu-Ja Huang are the lead authors of the paper.

Oxygen sensitivity

The human gut’s complex microbiome environment is difficult to model using animals such as mice, in part because mice eat a very different diet from humans, Griffith says.

“We’ve learned a huge amount from mice and other animal models, but there are a lot of differences, especially when it comes to the gut microbiome,” she says.

Most of the bacteria that live in the human gut are anaerobic, meaning that they do not require oxygen to survive. Some of these bacteria can tolerate low levels of oxygen, while others, such as F. prausnitzii, cannot survive oxygen exposure, which makes it difficult to study them in a laboratory. Some researchers have designed devices in which they can grow human colon cells along with bacteria that tolerate low levels of oxygen, but these don’t work well for F. prausnitzii and other highly oxygen-intolerant microbes.

To overcome this, the MIT team designed a device that allows them to precisely control oxygen levels in each part of the system. Their device contains a channel that is coated with cells from the human mucosal barrier of the colon. Below these cells, nutrients are pumped in to keep the cells alive. This bottom layer is oxygen-rich, but the concentration of oxygen decreases toward the top of the mucosal cell layer, similarly to what happens in the interior of the human colon.

Just as they do in the human colon, the barrier cells in the channel secrete a dense layer of mucus. The MIT team showed that F. prausnitzii can form clouds of cells in the outer layer of this mucus and survive there for up to four days, in an environment that is kept oxygen-free by fluid flowing across it. This fluid also contains nutrients for the microbes.

Using this system, the researchers were able to show that F. prausnitzii does influence cell pathways involved in inflammation. They observed that the bacteria produce a short-chain fatty acid called butyrate, which has previously been shown to reduce inflammation. After butyrate levels went up, the mucosal cells showed a reduction in the activity of a pathway called NF kappa B. This reduction calms inflammation.

“Overall, this pathway has been reduced, which is really similar to what people have seen in humans,” Zhang says. “It seems that the bacteria are desensitizing the mammalian cells to not overreact to the dangers in the outside environment, so the inflammation status is being calmed down by the bacteria.”

Patients with Crohn’s disease often have reduced levels of F. prausnitzii, and the lack of those bacteria is hypothesized to contribute to the overactive inflammation seen in those patients.

When the researchers added butyrate to the system, without bacteria, it did not generate all of the effects that they saw when the bacteria were present. This suggests that some of the bacteria’s effects may be exerted through other mechanisms, which the researchers hope to further investigate.

Microbes and disease

The researchers also plan to use their system to study what happens when they add other species of bacteria that are believed to play a role in Crohn’s disease, to try to further explore the effects of each species.

They are also planning a study, working with Alessio Fasano, the division chief of pediatric gastroenterology and nutrition at Massachusetts General Hospital, to grow mucosal tissue from patients with celiac disease and other gastrointestinal disorders. This tissue could then be used to study microbe-induced inflammation in cells with different genetic backgrounds.

“We are hoping to get new data that will show how the microbes and the inflammation work with the genetic background of the host, to see if there could be people who have a genetic susceptibility to having microbes interfere with the mucosal barrier a little more than other people,” Griffith says.

She also hopes to use the device to study other types of mucosal barriers, including those of the female reproductive tract, such as the cervix and the endometrium.

The research was funded by the U.S. National Institutes of Health, the Boehringer Ingelheim SHINE Program, and the National Institute of Environmental Health Sciences.
