Enhanced mRNA Vaccine May Work Intranasally.

Researchers at MIT have developed an enhanced mRNA vaccine system that can elicit a greater immune response at lower doses. The vaccine technology is so potent that it may be useful for intranasal COVID-19 vaccines. This would have the benefit of localized immunity in the nasal mucus membranes that could kill the SARS-CoV-2 virus before […]

Etched Nanopillars Kill Bacteria, Fungi on Titanium Implants

Researchers at RMIT in Australia have developed a drug-free approach to kill bacteria and fungi that can infect surfaces on medical implants. Such pathogens can cause serious and difficult-to-treat infections around medical implants, sometimes requiring the removal of the implant. In addition, many microbes are increasingly resistant to common anti (Read more...)

Device for Rapid COVID-19 Breath Testing

Researchers at Washington University School of Medicine have developed a COVID-19 breathalyzer test. The technology requires someone to breathe into it just once or twice, and it can then provide an indication if the person is infected with SARS-CoV-2 in as little as one minute. The device could be very useful fo screening large numbers […]

Peptoid Oligomers Target Viral Membranes

Researchers at New York University have developed a new method to target many viruses that cause disease. For viruses with a lipid membrane, which includes many that commonly cause disease, this new technique could prove to be fatal. By targeting the lipid membrane, the approach may circumvent the treatment resistance that arises when viruses mutat (Read more...)

UV-Free Air Decontamination: Interview with Sorel Rothschild, VP at Quantum Innovations

LumaFlo, a medtech company based in Israel, has developed a decontamination technology that does not require UV light, something that can be dangerous for people nearby. The COVID-19 pandemic highlighted the need for safe and effective decontamination technologies for both public spaces and healthcare facilities. However, many such technologies rel (Read more...)

Bacteriophages to Diagnose and Treat Bladder Infections

Researchers at ETH Zurich have developed a bacteriophage system to identify and treat bacterial bladder infections. Bacteriophages are viruses that infect bacteria, but these microorganisms have fallen out of favor as a treatment method for infection since antibiotics came along. Well, antibiotics are looking increasingly shaky as bacteria evolve t (Read more...)

App Converts Smartphone to Clinical Thermometer

Researchers at the University of Washington have developed an app that converts common smartphones into clinical thermometers. Spotting the signs of fever early could make a difference in providing early treatment or beginning a period of isolation to reduce the chance of disease transmission. This is particularly important for viral diseases, such (Read more...)

Microfluidic Chip Aids Tuberculosis Diagnosis

Researchers at the University of London have collaborated with QuantuMDx, a medtech company based in the UK, to develop a microfluidic diagnostic device for tuberculosis. The CAPTURE-XT chip is designed to concentrate and purify Mycobacterium tuberculosis from suspected tuberculosis patients, particularly in areas that lack access to routine diagno (Read more...)

CRISPR Combined with Glowing Proteins for Viral Detection

Researchers at Eindhoven University of Technology in the Netherlands have developed a sensitive diagnostic test for viral pathogens that is suitable for use in low-resource regions. The test is based on CRISPR proteins that can detect viral genetic material but also incorporates luciferase proteins, which are bioluminescent proteins that are natura (Read more...)

HIV Vaccine Candidate Stops Virus As it Enters Body

Researchers at the Texas Biomedical Research Institute are developing a vaccine candidate against HIV. The vaccine is intended to block HIV entry into the body and is administered to the mucosal lining of the rectum and vagina to achieve this. The formulation then stimulates antibodies against HIV in precisely the areas where the virus first [&hell (Read more...)

Electrostatic Face Mask Self-Charges with Breathing

Researchers at City University of Hong Kong have developed an electrostatically charged face mask that can replenish its charge through the wearer’s breathing action. The electrostatic charge helps the mask to adsorb tiny particles, such as SARS-CoV-2 viruses. However, such masks typically lose their charge and ability to bind particles over (Read more...)

NextGen COVID-19 Antibodies Destroy Spike Protein

Researchers at the Garvan Institute of Medical Research in Australia have developed a new generation of antibodies to treat COVID-19. So far, the antibodies have been shown to neutralize several of the viral variants behind COVID-19, and the researchers hope that they will form an effective treatment for at-risk patients. Previously developed antib (Read more...)

Electrochemical Sensor for Detailed SARS-CoV-2 Immunity Data

Researchers at the Harvard Wyss Institute have developed an electrochemical device, called the eRapid sensor, that can assist clinicians in quickly characterizing someone’s COVID-19 infection, including identifying the infecting viral variant and the nature of someone’s immunity to the virus in terms of whether it is vaccine-mediated or (Read more...)

Voice-Activated Sample Prep for Safer Handling

Researchers at Kyung Hee University in South Korea have developed a voice-activated DNA sample pre-treatment device to assist clinicians dealing with outbreaks of infectious disease to stay safer. Dealing with highly infectious patient samples puts clinicians and lab technicians at risk. Minimizing sample handling and exposure is important in reduc (Read more...)

Toolbox to Study Ligand Binding for Enhanced Treatments

Researchers at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have developed a DNA toolbox that allows researchers to explore binding interactions between ligands and their respective receptors based on receptor density and arrangement. The basis for many pharmacological interactions between drugs and cells, and indeed (Read more...)

Ferrobot Swarms for Rapid Viral Testing

At the University of California Los Angeles, scientists have developed a handheld lab kit that can conduct automated pooled testing for viral diseases, including COVID-19. The technology consists of a microfluidic platform that relies on swarms of magnetic discs, which the researchers have termed “ferrobots”, to shuttle samples through (Read more...)

Micelle Technology Detects Airborne SARS-CoV-2

At the Pacific Northwest National Laboratory, researchers have developed micelle technology that can detect minute amounts of SARS-CoV-2 in the air. This new capability could provide invaluable monitoring systems to detect viral contamination in healthcare facilities and beyond. Micelles are somewhat similar to liposomes in that they are both like (Read more...)
