PLGA(聚乳酸-羟基乙酸共聚物)

聚乳酸-羟基乙酸共聚物（Poly(lactic-co-glycolic acid)）是一种由乳酸（Lactic Acid，LA）和羟基乙酸（Glycolic Acid，GA）单体共聚而成的生物可降解高分子材料。

可用于：组织工程支架，药物载体，骨修复、骨固定材料，医用缝合线，面部填充剂等。

1.具有优异的生物相容性，不易引起免疫反应或毒性反应，适用于生物医学应用。

2.具有生物可降解性，在体内可自然降解成乳酸和羟基乙酸，这两种物质都是人体代谢途径的副产物，因此PLGA的降解产物对人体无毒无害。

3.具有可控降解性，通过调整乳酸和羟基乙酸的比例，可以调控PLGA的降解速度，因此可以实现对药物的控制释放，从而减少药物的系统副作用，并提高治疗效果。

4.具有良好的加工性能，可以加工成多种形态，如微球、纳米颗粒、薄膜、纤维等。

PLGA

Poly(lactic-co-glycolic acid) is a biodegradable polymer synthesized from lactic acid (LA) and glycolic acid (GA) through copolymerization.

Applications:

lTissue engineering scaffolds

lDrug carriers

lBone repair and fixation materials

lMedical sutures

lFacial fillers

Key Features:

1. Excellent biocompatibility—low risk of immune or toxic reactions, making it suitable for biomedical applications.

2. Biodegradable—naturally degrades into lactic acid and glycolic acid, which are readily metabolized in the body, ensuring biocompatibility and safety.

3. Controllable degradation—degradation rate can be adjusted by altering the ratio of lactic acid to glycolic acid, allowing for controlled drug release to minimize side effects and improve treatment efficacy.

4. Versatile processability—can be processed into microspheres, nanoparticles, films, and fibers.
