Good price biodegradable medical grade plga powder

Description

PLGA has good biocompatibility, bioabsorbability, biodegradability. It undergoes hydrolysis in the body to produce the original monomers, lactic acid and glycolic acid. These two monomers under normal physiological consitions, they are the by-products of various metabolic pathways in the body. Since the body effectively deals with the two monomers, there is minimal systemic toxicity associated with using PLGA for drug delivery or biomaterial applications. Also, the possibility to tailor the polymer degradation time by altering the ratio of the monomers used during synthesis has made PLGA a common choice in the production of a variety medicine devices, such as, orthopedics, maxillfacial, microspheres for drug delivery etc.
