Researchers at the Harvard Wyss Institute and MIT have developed a face mask that can detect SARS-CoV-2 in a wearer’s breath. The mask employs freeze dried molecular components including CRISPR-based technology, and a lateral flow assay strip to detect the virus and alert the wearer. To initiate the test, the wearer simply presses a button [& (Read more...)
Microarray Rapidly Identifies Antibodies Against SARS-CoV-2
Researchers at the Technical University of Munich in Germany have developed a sensitive and inexpensive microarray technology that can rapidly identify antibodies against the SARS-CoV-2 virus in blood or serum samples. The test can provide a result in as little as eight minutes, but the researchers believe that this can be further reduced to just [ (Read more...)
Rapid Diagnosis of Infectious Disease at Point of Care: Interview with Shawn Marcel, CEO of Torus Biosystems
Torus Biosystems, a medtech startup that spun out of Harvard’s Wyss Institute for Biologically Inspired Engineering, has developed the Synestia system, a point of care diagnostic tool for infectious disease. The system aims to provide rapid, point-of-care identification of pathogens, and incorporates microarray and qPCR technology. &nbs (Read more...)
AI-Powered App Interprets HIV Test Results
Researchers at University College London and the Africa Health Research Institute have developed an AI-powered app that can interpret lateral flow tests for HIV. The technique involves taking an image of the test with a smartphone camera, and the app can tell whether the result is positive or negative simply by analyzing the image. As […]
Nanodecoys Bind SARS-CoV-2 for Destruction by Immune System
Researchers at North Carolina State University have developed a nanodecoy system that provides binding sites for the SARS-CoV-2 virus. The vesicles help to prevent the virus from binding to lung cells and lead to its eventual destruction by the immune system. The nanodecoys are derived from lung spheroid cells, and contain the angiotensin-convertin (Read more...)
Graphene Sensor for Rapid COVID-19 Detection
Researchers at the University of Illinois Chicago have developed a graphene-based sensor that can rapidly detect the SARS-CoV-2 virus. The system includes graphene sheets that are coupled with an antibody against the viral spike protein. When viral particles bind to the antibodies, they change the vibrational properties of the graphene sheets, and (Read more...)
AirPop Active+ Halo Smart Mask: Medgadget Review
It’s often said that “necessity is the mother of invention,” and that has certainly shown to be true with the ongoing COVID-19 pandemic. One medical product that has seen a re-innovation of sorts, in both fashion and function, is the face covering. What has been historically an item seen primarily in healthcare and industrial sett (Read more...)
Engineered Surfaces Reduce Bacterial Attachment and Growth
Researchers at Monash University in Australia have developed a technique to create 3D engineered surfaces that reduce bacterial growth. Their approach could lead to frequently touched surfaces in healthcare facilities that result in less bacterial transmission. This should lead to a reduction in the incidence of hospital acquired infections, such a (Read more...)
Electrospun Nanofibers Filter 99.9% of Coronavirus Aerosols
Researchers at the University of California, Riverside have developed a nanofiber filter that is highly effective at removing coronavirus aerosols from air. As a major source of COVID-19 transmission, aerosols pose an ongoing threat. Technologies to remove aerosols from the air in buildings or as part of personal protective equipment are being deve (Read more...)
Electrochemical Device Detects SARS‑CoV‑2 Spike Protein in 1 Second
Researchers at the University of Florida and the National Chiao Tung University in Taiwan have developed a microfluidic device that can detect the SARS‑CoV‑2 spike protein in a saliva sample within one second. The electrochemical device employs antibodies against the spike protein to detect the virus, and could allow for ultra-rapid COV (Read more...)
