poly(lactic-co-glycolic acid) (PLGA)

Poly(lactic-co-glycolic acid) (PLGA) is a biodegradable synthetic polymer used in medical applications, especially for delivering drugs and vaccines. It is made from lactic acid and glycolic acid, which naturally break down in the body over time. When used in medical devices or drug delivery systems, PLGA slowly dissolves, releasing its contents gradually, which helps achieve controlled treatment effects. Its safety, biocompatibility, and ability to degrade into harmless byproducts make it a popular choice in medicine, particularly for sustained-release therapies and tissue engineering.
