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...)

Caffeine-Containing Biocompatible Gels for Drug Delivery

Researchers at MIT have developed a biocompatible polymer gel with potential for drug delivery. The new gel uses caffeine as a gentle and biocompatible catalyst during its manufacture, unlike many other gels that require harsh catalysts or manufacturing conditions that can ruin sensitive biological drugs intended for delivery or pose health risks f (Read more...)

Anti-Microbial Nanotechnology: Interview with Adrian Fellows, Head of R&D at AGA Nanotech

AGA Nanotech, a medtech company based in the UK, has developed nanotechnologies aimed at overcoming antimicrobial resistance, with a view to offering an alternative to conventional antibiotics. The company has collaborated with researchers from University College London to create poly(lactic-co-glycolic acid) (PLGA) nanoparticles that can deliver h (Read more...)

Injectable Bandage Stops Bleeding Wounds from Inside

At Texas A&M University researchers have developed a therapeutic hydrogel for injecting into bleeding wounds that can significantly speed up the hemostasis. The new injectable hydrogel material consists of nanosilicates, which are nanoparticles made from common minerals, and a thickening agent used in food preparation called kappa carrageenan. (Read more...)

Bacteria Coerced to 3D Print Nanocellulose Implants

In a quest to make more realistic, safer, and personalizable tissue replacement implants, bacterial cellulose nanofibers are being looked on as a viable material. They are naturally biocompatible, biodegradable, withstand heat well, and have physical properties similar to many of our tissues, when composed into larger objects. Bacterial cellulose n (Read more...)

Tooth Sensor Measures Intake of Sugar, Salt, Alcohol

Having an accurate record of food and alcohol intake is important for managing a number of diseases including diabetes, various cardiovascular conditions, and alcoholism. Currently, not much practical technology is available to do this aside from smartphone apps, and apps tend to be tedious and require constant vigilance of making sure to input all (Read more...)

Nanofiber Dressings Speed Up Healing of Serious Wounds

Researchers at Harvard University have come up with two new wound dressings that promote healing without relying on growth factors, cells, or even artificial scaffolds. Instead, natural proteins that are found in soy and human fetus cells are made to speed up the body’s natural healing processes, including performing tricks that only fetal ti (Read more...)
