PLGA biomedical device, SEM PLGA biomedical device, coloured scanning electron micrograph (SEM). PLGA, or poly(lactic-co-glycolic acid), is a copolymer used in a variety of biomedical devices such as grafts, sutures (stitches), implants, prosthetic devices, and micro and nanoparticles for drug delivery. PLGA is particularly well suited to these uses as a result of its biodegradability and bio-compatibility - It breaks down in the body to produce lactic acid and glycolic acid, both of which occur naturally in the body. One PLGA drug delivery device is currently used for the treatment of prostate cancer. Credit |
