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 … Continue reading

Graphene Spike Coating for Implants Kills Any Bacteria Trying to Settle

Graphene, the material that consists of a one atom thick layer of carbons, is so impressive that its development was awarded a Nobel Prize in physics. To add to its abilities, researchers at Chalmers University of Technology in Sweden used it to create microscopic spikes that kill bacteria upon contact. Because our native cells are … Continue reading

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 … Continue reading

Researchers Release Instructions to Convert 3D Printers Into Bioprinters

If you want to try doing 3D bioprinting at home or at a budget-strapped lab, commercial devices that only start at $10,000 may be out of reach. But researchers at Carnegie Mellon University have now published a series of instructions, as part of a study in Elsevier’s journal HardwareX, that let you turn a cheap … Continue reading

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 for patients. The … Continue reading

Hair-Sized Fiber-Optic Probe Can Measure Temperatures Deep Inside the Body

Researchers at the University of Adelaide have developed a tiny fiber-optic probe that can measure temperatures deep inside the body, while imaging structures in the region of interest. The probe, which has a similar thickness to a human hair, could help researchers to investigate the effects of drugs that raise temperatures in specific parts of … Continue reading

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. It can be produced for pennies per … Continue reading

First FDA Clearance for Software to 3D Print Patient Specific Anatomical Models

Materialise, a company specializing in 3D printing based in Belgium but with offices around the world, won FDA clearance for its Mimics inPrint software to be used for 3D printing of anatomical models for diagnostic applications. The software allows hospitals to print one-to-one reproductions of individual patient anatomy, thereby helping surgeons to understand the unique … Continue reading

Kirigami-Inspired Material Can Adhere to Flexible Surfaces for Improved Bandages and Wearables

Researchers at MIT have developed a thin, light-weight film that can securely adhere to flexible and deformable parts of the body, such as the knee and elbow. The key to the sticking-power of the material lies in a series of slits the researchers have cut into it, inspired by the Asian art of kirigami, which … Continue reading
