Nanowire Implants for Controlled Release of Drugs
September 29, 2015 | Terry Sharrer
Pyrrole is a naturally occurring aromatic compound, originally discovered in coal tar, but later found in a variety of substances from bile pigments, to vitamin B12 and chlorophyll. It has a conductive nature which gives polypyrrole the ability to form nanowires. Researchers at Purdue University have used this material to form nanowire devices which can be loaded with medicinal drugs and implanted in the body, where they the can be time-released with the application of an electromagnetic field. Placed in tumors, or at sites of bone injury, this approach could minimize the systemic side effect of chemotherapy. MORE
