Desktop Air Curtain Blocks Infectious Aerosols

Researchers at Nagoya University in Japan have developed a desktop air curtain system that prevents aerosols, such as airborne COVID-19 particles, from passing through it. The technology improves on some existing air curtain solutions that can create turbulent flow, resulting in the escape and spread of aerosols. The desktop device contains a dedic (Read more...)

New Antimicrobial Surface for Implantable Devices

Researchers at the University of California Los Angeles have created a zwitterion polymer coating for in-dwelling medical devices, such as urinary catheters, that prevents microbes from adhering and creating troublesome biofilms. Recurrent infection and biofouling are a serious problem for such devices, leading to the overuse of antibiotics and the (Read more...)

Multiplex Immunoassay for Dengue Diagnosis

Researchers at the University of Reading in the UK created a rapid multiplex immunoassay for the detection of Dengue fever. The technology, which the researchers call the Cygnus system, aims to provide improved sensitivity compared with lateral flow tests and improved convenience and speed compared with conventional lab tests. As a point-of-care de (Read more...)

Spray Blocks SARS-CoV-2 Entry into Nasal Cells

Researchers at the University of British Columbia, and collaborators, created a nasal spray that can block the entry of SARS-CoV-2 into cells in the nasal cavity, potentially offering protection and treatment for COVID-19. Excitingly, in lab tests, the spray appears to work against all known variants of the virus, including the Omicron variant, whi (Read more...)

Multi-Purpose Sensor for Rapid, Accurate COVID-19 Testing

Researchers at Johns Hopkins University developed a COVID-19 testing technology that is based on surface enhanced Raman spectroscopy (SERS) coupled with machine learning. The technique does not require sample preparation or special training and can deliver results in as little as 25 minutes, with an accuracy that is comparable to that of PCR, the c (Read more...)

Lymphoid Follicle Chip Models Complex Immune Responses

Researchers at the Harvard Wyss Institute have created a microfluidic chip that contains lymphoid follicle-like structures, allowing them to model complex immune responses to various pathogens and vaccines. The breakthrough could let scientists to more comprehensively probe the complex workings of the immune system. Lymphoid follicles are found in (Read more...)

Capsule Delivers and Injects mRNA into Stomach

Researchers at MIT have created an oral mRNA delivery system that could provide an alternative to injectable mRNA vaccines. It could also enable RNA or DNA therapies that are intended to treat gastrointestinal diseases. mRNA has shown its therapeutic potential in spectacular fashion, providing the powerhouse behind some of the world’s most su (Read more...)

Quick and Accurate COVID Test Uses LAMP Assay

Researchers at the University of Washington developed a new COVID testing technology that can provide accurate results in as little as 30 minutes. The technology intends to be a bridge between PCR tests, which are accurate but slow, and antigen tests, which are rapid but suffer from reduced accuracy. The system provides results straight to [&hellip (Read more...)

Cheap and Portable COVID-19 Test Lab

Researchers at Queen Mary University of London have created a low-cost, portable COVID testing kit intended for use in remote, low-resource regions of the world. They describe the approach as a lab-in-a-backpack, and it makes use of a recycled computer hard-drive as a centrifuge. The test assay relies on loop mediated isothermal amplification (LAMP (Read more...)

Anti-COVID Nanobubbles Act as Viral Decoys

Researchers at Northwestern University have discovered naturally-occurring extracellular vesicles in the blood that contain the ACE2 protein, which is the cellular target of SARS-CoV-2. The vesicles act as a binding site for viral particles within the body, and prevent them from binding to and infecting cells. Unlike vaccines, therapeutics based on (Read more...)

Wearable Air Sampler to Assess SARS-CoV-2 Exposure

Researchers at Yale University created a wearable air sampler clip that can be worn on clothing and which can bind aerosols present in the environment. The clip can later be analyzed to determine the level of SARS-CoV-2 exposure while it was worn. The low-cost, battery-free technology could allow people to identify unsafe indoor environments that [ (Read more...)

Quantum Sensor to Detect SARS-CoV-2 More Accurately

Researchers at MIT have designed a quantum sensor to detect SARS-CoV-2. While the device is still theoretical, the researchers have used mathematical simulations to show its potential, and the data and design indicate that it may be faster, more accurate, and less expensive than the current gold-standard technique, PCR. The system is based on nanod (Read more...)

Therapeutic Fusion Protein Inhibits SARS-CoV-2

Researchers at the Technical University of Munich in Germany have developed a new protein therapeutic against SARS-CoV-2. Unlike previously developed antibody therapies and vaccines, the virus is very unlikely to be able to circumvent this latest technology through mutation, as it is based on the viral target site in the body, the ACE2 receptor. Th (Read more...)

High Surface Area Copper for Enhanced Antibacterial Activity

At RMIT University in Australia a team of scientists developed a copper alloy that can kill bacteria on its surface 100 times faster than regular copper. The researchers created the material using copper and manganese atoms, and then removed the manganese after the material was formed, resulting in a comb-like copper structure with massively increa (Read more...)

Flu Virus-Inspired Nanoparticles for mRNA Delivery

Researchers at the University of California San Diego developed a new delivery technique for mRNA. The method involves flu virus-inspired nanoparticles that can escape endosomes, the acidic vesicles that engulf and destroy materials that attempt to enter cells. The nanoparticles contain a protein receptor that allows them to unlock the endosomes an (Read more...)
