## Abstract In this article, we cover the development of Lβlactide (LβLA) random copolymers into which useful compounds, such as repellents and antibacterial agents, were impregnated by high concentration. Outstanding controlled release materials were developed with statistical random copolymers of
Puerarin nanoparticles were firstly prepared in the process of solution-enhanced dispersion by supercritical CO 2 (SEDS) and then successfully microencapsulated by poly(L-lactide) (PLLA) in a modified SEDS process. By adding an organic non-solvent, an initial puerarin solution with a higher degree o
