Electrochemical Test Measures Antibiotic Resistance

Researchers at Washington State University have developed an electrochemical test that can rapidly identify antibiotic-resistant bacteria in patient samples. The technology can provide a result in less than 90 minutes, and is based on measuring the electrochemical activity of the bacteria after they are exposed to antibiotics. The data reveal the m (Read more...)

Simple Color Change Test Identifies Wound Infections

Researchers at the University of Bath in the UK, along with outside collaborators, have developed a simple color change test that rapidly indicates whether a wound is infected with harmful bacteria. The test works by detecting virulence factors released by the bacteria, which prompt a simple color change in a solution. The test could help [… (Read more...)

Breath Test Developed for COVID-19

Researchers at Ohio State University managed to develop a breath test for COVID-19 that can spot the infection within seconds. The basis for the test is a unique ‘breath print’ of COVID-19 that the researchers have identified, and this includes a specific combination of oxygen, nitric oxide, and ammonia in the breath. At this stage [&he (Read more...)

COVID-19 Vaccine Patch Does Not Require Cold Chain Transport

Researchers at the University of Queensland and Vaxxas, a medtech company, announced the development of a high-density microarray patch (HD-MAP) that can deliver a COVID-19 vaccine through the skin without the need for needles. While such minimally invasive vaccine technology is to be welcomed, the major breakthrough is the temperature stability of (Read more...)

Battery-Free Device Acts as Artificial Cochlea

Researchers at the Huazhong University of Science and Technology in China created a battery-free device that could pave the way for an artificial cochlea to aid with hearing loss. The cochlea, a component of the inner ear, converts sound waves into electrical impulses, and the new device performs a similar function. The device consists of [… (Read more...)

Carbon Nanotube Sensor Detects SARS-CoV-2 Within 5 Minutes

Scientists at MIT announced the development of a rapid COVID-19 test that can detect the virus in a saliva sample in as little as five minutes. The technology does not require antibodies or other expensive reagents typically associated with protein detection, and is instead based on carbon nanotubes. The nano-structures are encased in a web [&helli (Read more...)

DNA Aptamers for Rapid COVID-19 Testing: Interview with Steven Goh, CEO of Achiko and Dr. Michael Edel, Inventor of AptameX

Achiko, a company based in Switzerland, has developed AptameX, a saliva-based rapid COVID-19 test. The technology is based on DNA aptamers that are bound to gold nanoparticles. On binding with a viral protein the gold nanoparticles are released, causing a measurable color change. The test takes approximately 15 minutes in total, with the user spend (Read more...)

Iron Oxide Nanoparticles Suppress Oral Biofilms

Collaborators from University of Pennsylvania and Indiana University have tested a ‘”nanozyme” system designed to reduce dental plaque. The technology consists of iron oxide nanoparticles that are applied to tooth enamel before a follow-up rinse of hydrogen peroxide. The nanoparticles act as an “enzyme” to activate the (Read more...)

Antibiotic Combined with Neutrophil Attractant

Researchers at Monash University in Australia and Harvard University have developed a new treatment for infections caused by antibiotic-resistant bacteria. To achieve this, they attached a chemoattractant to an antibiotic drug molecule, meaning that it attracts neutrophils to the site of an infection and primes them to kill the bacteria. The two-pr (Read more...)

Vaccine Delivery Device Inspired by BBQ Lighter

A team at Georgia Tech tinkered together a battery-free electroporation device to deliver DNA vaccines, which is inspired by BBQ lighters. The details of the workings of the vaccine injector are described in Proceedings of the National Academy of Sciences. The electric ‘spark’ that ignites the gas flowing from a BBQ gas lighter has been (Read more...)

Robotic Textiles for Breathing Recovery

Researchers at MIT, alongside collaborators from Uppsala University and KTH Royal Institute of Technology in Sweden, developed a ‘robotic textile’ that consists of an array of actuatable fibers. The fiber actuators are powered using compressed air, and can perform an impressive array of movements. Garments made using such fibers can sen (Read more...)

Wearable, Non-Invasive Sensor Measures Glucose in Sweat

Scientists at Penn State University developed a wearable glucose monitor that can non-invasively measure glucose levels within sweat in real time. The low-cost sensor consists of laser-induced graphene and a nickel-gold alloy that can detect the very low levels of glucose in sweat without the use of enzymes. The sensor contains a microfluidic chamb (Read more...)

Improving Medication Compliance with Connected Pill Bottles and More: Interview with Chris O’Brien, CEO at AdhereTech

AdhereTech, a medtech company based in New York City, has developed the Aidia Smart Bottle (previously known as the Smart Pill Bottle), a connected pill bottle that helps to increase medication compliance using lights, audio alerts, and text message reminders. The bottle will remind patients to take their medication and remind them if they have [&h (Read more...)

Exoskeleton Helps Above-Knee Amputees to Walk

Researchers at the University of Utah built an exoskeleton that can ease walking for people with above-knee amputations. The new system, which uses an electromechanical actuator attached to the thigh and AI to adapt to each person’s walking style, significantly reduces energy consumption for users. Above-knee amputations are particularly chal (Read more...)

Telemedicine to Monitor At-Risk COVID-19 Patients at Home

Researchers at the Technical University of Munich in Germany have developed a telemedicine system for high-risk COVID-19 patients who are isolating at home. The system consists of an ear sensor that monitors a variety of physiological parameters, including heart rate, respiration, oxygen saturation, and body temperature. The project also involves c (Read more...)

Customized, Battery-Free Wearables Made to Fit Perfectly

At the University of Arizona a team of engineers have developed 3D-printed wearable devices that are custom made for each user.
