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

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 spending

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 hydrogen peroxide, generating reactive oxygen species and killing

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-pronged technique could give

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

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 sense how they’re stretched and

Alva Health, a medtech startup based in Connecticut, is developing a wristband that can detect the signs of stroke and promptly alert the wearer and/or healthcare staff. The technology is intended for those at high risk of stroke, such as stroke survivors and those diagnosed with transient ischemic attack. Strokes cause a huge level of

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 chamber into

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

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 challenging in terms of walking. Many

As cloud and digital platforms continue to gain traction, we’re seeing a trend toward increased investments in robotic surgery in medical technology fields. Surgical training, coordination, and collaboration in the operating room are areas where digital tools can help shorten learning curves. While robotic technology continues to transform healthcare worldwide by allowing surgeons to perform

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 clinicians calling the patient daily

Luminopia, a company based in Cambridge, MA, has developed Luminopia One, a visual content system that aims to treat amblyopia, also known as ‘lazy eye,’ in young children. The condition is caused by neurological deficits that typically affect vision in one eye. At present, the condition is treated using corrective glasses, eye patches, or eye

At the University of Arizona a team of engineers have developed 3D-printed wearable devices that are custom made for each user. The personalized fit means that they do not require adhesives to stay in place. The technology can be used to monitor a variety of physiological parameters, including body temperature and muscle deformation during physical

A collaboration between groups at MIT and Dana-Farber Cancer Institute led to the creation of a system that allows for quick determination of the susceptibility of cancer cells to specific drugs, without the need to rely on genomic markers. The technique consists of flowing the cells through vibrating microchannels, which lets the researchers obtain single

At the University of Bern in Switzerland, researchers have developed the Panoramic Opto-Electrical Measurement and Stimulation (POEMS) system, which allows them to conduct advanced optogenetic experiments with mouse hearts. The device, which contains a volume into which a mouse heart can be placed, lets the Swiss team stimulate various cell types using light, and then

A team of scientists at University of California Los Angeles created a magnetoelastic device that can generate electricity from movements of the body, including the movements caused by the pulse at the wrist. The patch-like device may help to power medical wearables or implantable sensors, and may function as a waterproof heart rate monitor in

Evolution Devices, a company based in California, created a functional electrical stimulation device to assist people with foot drop to walk more freely. Foot drop is caused by muscle weakness/paralysis, and those affected struggle to lift the front part of their foot, which makes walking difficult and can lead to falls. The product is called

Scientists at Ecole Polytechnique Fédérale de Lausanne in Switzerland created a wireless photoelectric implant that allows them to activate or suppress certain neurons in the mouse spinal cord. The flexible implant is controlled through Bluetooth and contains miniaturized LEDs that emit red light, which helps to avoid absorption and reflection by nearby neurons. The researchers

Researchers at the University of Illinois Urbana-Champaign have developed a sensor that can rapidly detect a virus in a sample. It can also identify whether the viral particles are still infectious. So far, the researchers have trialed the technology to detect human adenovirus and SARS-CoV-2. It can provide an answer between 30 minutes and two
