PLLA (Poly-L-Lactic Acid)
PLLA are biocompatible, non-toxic and harmless to human body after being degraded in the body through metabolism.
Therefore, PLLA are widely used in the medical field, such as controlled-release and slow-release drug carrier; tissue engineering scaffolds, cardiovascular scaffolds, bone fixation, and bone repair materials (such as absorbable screws, absorbable bone plates), microcapsules for injection, microspheres, implants and animal organ support elastomers, etc.
