Cold Plasma Made Useful to Sterilize Medical Equipment

Cold plasma is a popular topic of research at Purdue University, including as a potential tool for killing cancer cells. It’s cold in the sense that only the electrons within the material are heated up to thousands of degrees, while the rest of the gaseous substance remains near room temperature. Now researchers at Purdue University [… (Read more...)

New Coating for Dental Aligners Keeps Bacteria from Growing

Dental aligners, also known as retainers, are plastic devices that are used to slow adjust the position of the teeth. They’ve become extremely popular, but they require frequent changes because bacteria is known to make a home within the devices’ many small curves. Now a team of Korean researchers have developed a coating that can [&hel (Read more...)

3D-Printed Smart Gel Could Form Artificial Muscles

Researchers at Rutgers University have developed a 3D-printed hydrogel that can move in response to an electrical signal. The material has potential in soft robotics, and could be used as an artificial muscle in prostheses or implants, or even for drug delivery applications. Soft robotics is a thriving area of research, and soft robots have [&helli (Read more...)

Easy Method of Separating Chiral Drug Molecules Discovered

The chiral difference between two molecules often plays a huge role in pharmacology and physiology, even though the two seem nearly identical. The difference, simply that they’re mirror images of each other, turns out to mean, for example, that some molecules of thalidomide cure morning sickness while their chiral twins lead to deformed child (Read more...)

Printing Functional Electronics Directly Onto Skin

University of Minnesota researchers have figured out a way of printing electronics on top of skin, even onto hands that are unrestrained and slightly moving. We got a peek at the technology in the Fall of last year, when it was first presented at the 2017 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) in […]

Device Keeps Implanted Pancreatic Islets Oxygenated and Alive

MIT researchers have developed a device to keep implanted pancreatic islets oxygenated and alive. The technique involves a replenishable oxygen reservoir and a coating that protects the cells from the immune system. In tests in diabetic rats, the subcutaneous implants kept nearly 90% of the islets alive for up to eight months, and blood glucose [&h (Read more...)

Silk-Based Polymer to Help Repair Damaged Bones

University of Connecticut researchers have created a new orthopedic material for fixing bones that’s made out of spider silk, itself one of the world’s strongest natural materials. While silk fibroin, the protein in silk that gives it strength, is already in use in sutures and other medical devices, this is the first time it was [&helli (Read more...)
