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.

Surface plasmon polaritons are a type of surface wave that, when harnessed, show potential to improve various processes that take place on the nanoscale, such as molecular imaging. Researchers from two places in Russia propose a new scheme using quantum dots and graphene to more efficiently convert light into surface plasmon polaritons for use in such applications.

Mid-infrared spectroscopy is an important tool for nondestructive analysis of molecules, but it cannot analyze nanometric volumes very well. One way to improve nanometric analysis is through a technique called nanofocusing, and researchers in Spain and Russia proposed an improved nanofocusing technique using graphene.
