Light-Activated Hydrogel Disrupts Oral Biofilms, Whitens Teeth

Researchers at Nanchang University in China developed a photodynamic hydrogel treatment for teeth that disrupts bacterial biofilms, helps to prevent cavities, and whitens teeth. The gel is applied to the teeth and is then activated using green light, which is less harsh on nearby skin than the high intensity blue light that is sometimes used for teeth...

Ultrasound Sticker for 48 Hours of Imaging

Engineers at MIT have created an ultrasound patch that can provide long-term ultrasound imaging of internal organs and structures. The device contains a rigid piezoelectric probe array and uses an underlying layer of elastomer-covered hydrogel in lieu of the gel applied to the skin during conventional ultrasound procedures. At just the size of a postage...

DNA-Based Nanorobot Interacts with Live Cells

Researchers at INSERM (Institut national de la santé et de la recherche médicale) in France, and collaborators, have developed a DNA-based nanorobot called the Nano-winch. The tiny creation is made using DNA molecules and a “DNA Origami” approach. The tiny robot is so small that it can land on a cell surface and interact with ‘mechanoreceptors’ that...

Sleep Monitoring at Home: Interview with Ziv Peremen, CEO of X-trodes

X-trodes, a medtech startup based in Israel, created Smart Skin, a wireless monitoring and analytics technology that is suitable for at-home sleep monitoring. At present, diagnosing sleep disorders is an arduous and expensive business, requiring patients to attend a specialized sleep clinic and wear bulky and uncomfortable equipment, all while attempting...

Nouhaus Red Dot Award-Winning Massage Chair: Our Review

Many of us can attest to the lumbar pains related to sitting at a desk for endless hours week after week. Even despite using an ergonomic office chair, the reality is that your muscles still need to be stretched and stimulated, otherwise you’ll still end up feeling sore. High-end massage chairs – don’t get me wrong, there’s a reason they are...

Upcycling CDs as Flexible Biosensors

A team of scientists at Binghamton University in New York State have developed a technique that lets them salvage material from old CDs to make flexible biosensors that are inexpensive and relatively simple to produce. The method involves using a chemical process and sticky tape to peel off the metal coating from the disks, and then using a crafting...

Lumen: World’s First Device and App for Real-time Metabolic Feedback

Lumen is the first device and app available to anyone that provides real-time feedback on whether you’re burning carbohydrates or fats. These measurements are usually only made for athletes or patients through special testing centers, hospitals, or clinics, but with Lumen they are now available to everyone, anywhere. Nutrition is a very individualized...

Silicone Heart Models Heart Failure

Scientists at the Royal College of Surgeons in Ireland and partners at the National College of Art and Design in Dublin have developed a silicone heart model that is intended to model heart failure with preserved ejection fraction. The device, which represents a ‘mock circulatory loop’, includes a simulated version of the left atrium and left ventricle,...

Point of Care Rapid PCR Test

Columbia University scientists and collaborators at Rover Diagnostics have created a rapid PCR test that can be used at the point of care. Weighing in at two pounds, the portable device can rival the sensitivity and accuracy of traditional lab-based PCR testing equipment, but providing results in as little as 23 minutes. The new device includes...

Spray Coating Fights Viruses and Bacteria

Researchers at the University of Sydney in Australia engineered a new spray coating for surfaces that provides long-term protection against bacterial and viral contamination. The material is intended as a long-term alternative to disinfectant sprays and combines hydrophobic properties with antimicrobial nanoparticles to reduce microbial contamination....
