Understanding PLLA Microspheres as a Material System
PLLA microspheres are polymeric particles derived from poly-L-lactic acid, a biodegradable polyester widely used in biomedical material science. Unlike finished medical products, PLLA microspheres themselves are intermediate materials whose performance depends strongly on polymer quality, particle structure, and processing technology....
Polycaprolactone (PCL) is a high-performance biodegradable polyester synthesized through the ring-opening polymerization of ε-caprolactone.
As a semi-crystalline polymer with excellent mechanical flexibility, chemical stability, and biocompatibility, PCL has attracted growing attention across medical, industrial, and sustainable materials applications.
