Bioactive glass offers numerous benefits as a coating material for metallic implants, but achieving strong adhesion between the glass and implant is a challenge. University of Barcelona researchers explored several strategies for improving the adhesion strength of bioactive glass coatings deposited using atmospheric plasma spraying.

Continuous glucose monitoring systems can help alleviate the mental burden of diabetes management, but there are limitations to powering current systems. Researchers at ETH Zurich developed a self-sufficient glucose monitoring system that not only registers excess glucose but initiates the release of insulin into the blood. They successfully tested the device in mice.

Most rotator cuff repair procedures focus on the tendon, but the real problem is that the muscle degenerates and accumulates fat. University of Connecticut School of Medicine researchers led by ACerS Fellow Cato Laurencin developed a graphene-polymer matrix that induces a reversal of muscle degeneration, thereby greatly lowering the risk of rotator cuff retear injuries.

Glucose fuel cells allow for significant volumetric scale-down of implantable devices because they do not physically store energy like batteries. However, cells that use polymer-based electrolytes face some limitations. Researchers from MIT and the Technical University of Munich developed glucose fuel cells using a ceramic membrane that overcome these limitations.
