Camera Measures Blood Pressure with Quick Look

At the University of South Australia, researchers designed a system that allows them to measure a patient’s blood pressure with a camera. The camera visualizes the patient’s forehead and focuses on two regions in particular to optically determine photoplethysmographic signals that AI algorithms then convert to blood pressure data. The r (Read more...)

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...)

Extra Hot Nanoparticles for Cancer Therapy

Researchers at Oregon State University created a new type of hyperthermic magnetic nanoparticle that is intended to assist in destroying tumors through localized heating under an alternating magnetic field. Previous iterations of such technologies could heat up to about 44 degrees Celsius (111 F), which was only effective in easy-to-access tumors t (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...)

Implantable Device Adheres to Muscle, Treats Atrophy

Scientists at the Wyss Institute for Biologically Inspired Engineering at Harvard have developed a mechanically active gel-elastomer-nitinol tissue adhesive, otherwise known as MAGENTA. The implantable device functions as a soft robot, and it can be adhered to the outside of a muscle. When an electrical charge is applied to the device, a spring ins (Read more...)

Making Tumors Tastier for the Immune System

Researchers at The University of Texas MD Anderson Cancer Center have developed a nanotechnology platform that can make cancer cells more vulnerable to immune attack in the body. The researchers call their system the bispecific tumor-transforming nanoconjugate (BiTN) platform. The idea is to make solid tumors more appealing for the immune system by (Read more...)

Non-Invasive Spinal Modulation for Cerebral Palsy

SpineX, a medtech company based in California, has developed the Spinal Cord Innovation in Pediatrics (SCiP) device, a non-invasive spinal cord neuromodulation technology that is intended to treat children with cerebral palsy. The technology is designed to be used in conjunction with activity-based neurorehabilitation therapy with the goal of impro (Read more...)

Monitoring Congestive Heart Failure Through Speech: Interview with Tamir Tal, CEO of Cordio Medical

Cordio Medical, a medtech company based in Israel, has developed HearO, an app that can assist in monitoring congestive heart failure. The technology is based on the phenomenon whereby congestive heart failure patients demonstrate changes in their voice as their disease progresses or in advance of disease exacerbation. This includes lung sounds, su (Read more...)

Device Measures Hemoglobin More Accurately in Dark Skin

Researchers at the University of Texas at Arlington, in collaboration with Shani Biotechnologies, a local firm, have created a point-of-care device that can accurately measure hemoglobin levels and perform pulse oximetry in individuals with dark skin. At present, methods to determine hemoglobin levels at the point of care, such as pulse oximetry, a (Read more...)

Implanted Magnets for Prosthetic Control

Engineers at MIT have developed a system that could let users of robotic prostheses to more sensitively control their bionic limbs. The technology involves implanting pairs of small magnetic beads into muscles. When the muscles contract, the beads move closer together, allowing prosthetic devices to more precisely calculate a user’s intention (Read more...)

In-Office Pediatric Ear Tube Procedures: Interview with Preceptis Medical’s Greg Mielke

Preceptis Medical, a medtech company based in Minnesota, created the Hummingbird Tympanostomy Tube System. The device allows ear, nose, and throat (ENT) surgeons to insert ear tubes in the comfort of their office. The procedure requires only local anesthetic and is intended to be less distressing for pediatric patients than the conventional approac (Read more...)

Improved Membrane Coating for Anti-Cancer Nanoparticles

Scientists at the University of Eastern Finland have developed a technique that lets them improve the coating of nanoparticles when using cell membranes.
