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

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

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
