Researchers showcase new breakthroughs for unlocking the potential of plasmonics

Posted by in categories: materials, nanotechnology

Plasmonics are special optical phenomena that are understood as interactions between light and matter and possess diverse shapes, material compositions, and symmetry-related behavior. The design of such plasmonic structures at the nanoscale level can pave the way for optical materials that respond to the orientation of light (polarization), which is not easily achievable in bulk size and existing materials.

In this regard, “shadow growth” is a technique that utilizes vacuum deposition to produce nanoparticles from a wide range of 2D and 3D shapes at nanoscale. Recent research progress in controlling this shadow effect has broadened the possibilities for the creation of different nanostructures.

Now, in twin studies led by Assistant Professor Hyeon-Ho Jeong from the Gwangju Institute of Science and Technology (GIST), Republic of Korea, researchers have comprehensively shed light on the recent advances in shadow growth techniques for hybrid plasmonic nanomaterials, including clock-inspired designs containing magnesium (Mg).

Scientists manufacture a surface that has virucidal properties but does not use any chemicals

Posted by in categories: biological, chemistry

A team of researchers from the URV and the RMIT University (Australia) has designed and manufactured a surface that uses mechanical means to mitigate the infectious potential of viruses. Made of silicon, the artificial surface consists of a series of tiny spikes that damage the structure of viruses when they come into contact with it. The work is published in the journal ACS Nano.

The research has revealed how these processes work and that they are 96% effective. Using this technology in environments in which there is potentially dangerous biological material would make laboratories easier to control and safer for the professionals who work there.

Spike the viruses to kill them. This seemingly unsophisticated concept requires considerable technical expertise and has one great advantage: a high virucidal potential that does not require the use of chemicals. The process of making the virucidal surfaces starts with a smooth metal plate, which is bombarded with ions to strategically remove material.

Quantum material-based spintronic devices operate at ultra-low power

Posted by in categories: particle physics, quantum physics, robotics/AI

As artificial intelligence technologies such as Chat-GPT are utilized in various industries, the role of high-performance semiconductor devices for processing large amounts of information is becoming increasingly important. Among them, spin memory is attracting attention as a next-generation electronics technology because it is suitable for processing large amounts of information with lower power than silicon semiconductors that are currently mass-produced.

Utilizing recently discovered in spin memory is expected to dramatically improve performance by improving signal ratio and reducing power, but to achieve this, it is necessary to develop technologies to control the properties of quantum materials through electrical methods such as current and voltage.

Dr. Jun Woo Choi of the Center for Spintroncs Research at the Korea Institute of Science and Technology (KIST) and Professor Se-Young Park of the Department of Physics at Soongsil University have announced the results of a collaborative study showing that ultra-low-power memory can be fabricated from quantum materials. The findings are published in the journal Nature Communications.

New AI model designs proteins to deliver gene therapy

Posted by in categories: biotech/medical, robotics/AI

Researchers at the University of Toronto have used an artificial intelligence framework to redesign a crucial protein involved in the delivery of gene therapy.

The study, published in Nature Machine Intelligence, describes new work optimizing proteins to mitigate immune responses, thereby improving the efficacy of gene therapy and reducing side effects.

“Gene therapy holds immense promise, but the body’s pre-existing to viral vectors greatly hampers its success. Our research zeroes in on hexons, a fundamental protein in adenovirus vectors, which—but for the immune problem—hold huge potential for gene therapy,” says Michael Garton, an assistant professor at the Institute of Biomedical Engineering in the Faculty of Applied Science & Engineering.

Licensing NASA Tech: Bridging Government to Commerce

Posted by in categories: biotech/medical, government, information science, robotics/AI

While NASA is well-known for advancing various technologies for the purposes of space exploration, whether it’s sending spacecraft to another world or for use onboard the International Space Station (ISS), the little-known fact is that these same technologies can be licensed for commercial use to benefit humankind right here on the Earth through NASA’s Spinoff program, which is part of NASA’s Space Technology Mission Directorate and its Technology Transfer program. This includes fields like communication, medical, weather forecasting, and even the very mattresses we sleep on, and are all featured in NASA’s annual Spinoff book, with NASA’s 2024 Spinoff book being the latest in sharing these technologies with the private sector.

“As NASA’s longest continuously running program, we continue to increase the number of technologies we license year-over-year while streamlining the development path from the government to the commercial sector,” Daniel Lockney, Technology Transfer Program Executive at NASA Headquarters, said in a statement. “These commercialization success stories continually prove the benefits of transitioning agency technologies into private hands, where the real impacts are made.”

One example is a medical-grade smartwatch called EmbracePlus developed by Empatica Inc., which uses machine learning algorithms to monitor a person’s vitals, including sleep patterns, heart rate, and oxygen flow. EmbracePlus reached mass production status in 2021 and has been approved by the U.S. Food and Drug Administration (FDA) with the goal of using the smartwatch for astronauts on future spaceflights, including the upcoming Artemis missions, along with medical patients back on Earth.

Light My Fire: COUR Raises $105M Series A to Advance Tolerogenic Nanoparticles for Autoimmunity

Posted by in categories: biotech/medical, nanotechnology

Steve P. Miller, PhD, has spent much of his career figuring out how to shut off autoimmune responses when he observed dying cells acting as carriers of autoantigens that could modulate the immune system. More than 20 years ago, while a professor at Northwestern University’s Feinberg School of Medicine, Miller discovered that dendritic cells (DCs), a subtype of antigen-presenting cells (APCs), could be changed or turned off to send the right signals to make immunologically tolerant T cells, also known as “tolerogenic.”

Miller’s attention turned toward investigating how best to mimic the apoptotic cells, overriding the expression of dendritic cells. So, Miller partnered with polymer chemist Lonnie D. Shea, PhD, who was at the McCormick School of Engineering, to develop a nanoparticle that interacts effectively with dendritic cells.

In 2013, Miller and Shea helped launch a company spun out of Northwestern University, when Shea was still in Chicago, called Cour Pharmaceutical Development Company, to develop innovative nanobiological therapeutics for acute inflammation, autoimmune, and allergic conditions. After years of experimentation, they developed a formula for nanoparticles of the right size and charge that interact well with the immune system, which is the foundation for their proprietary antigen-specific immune tolerance platform.
