Property of PACA-co-PEG Microparticles as Drug-carrier
Abstract:
Amphithatic polymeric microparticles were prepared from copolymers of poly (alkyl cyanoacrylate) (PACA) and poly (ethylene glycol) (PEG) (PACA-co-PEG) by evaporation method.And drug-loaded copolymeric microparticles were formed by mixing polymeric microparticles with paracetamol (PCTM) as a simulated drug.The polymeric microparticles are round shaped with outer diameter <200 nm as determined by dynamic light scattering and transmission electron microscopy.The degradation rate of PECA-co-PEG was less than that of homopolymer PECA;while degradation rate of PECA was larger than that of PBCA (PECA:polyethyl cyanoacrylate;PBCA:polybutyl cyanoacrylate).
