摘要
The preparation of nanoparticles from 75% methylated poly( beta-L-malic acid) is described. Their degradation in aqueous environments was examined and the influence of pH and lipase on the rate of hydrolysis was evaluated. Six proteins were used to estimate the loading efficiency of the nanoparticles. The amount of protein retained in the nanoparticles was found to depend on the acid/basic character of the protein. Protein release from the loaded nanoparticles upon incubation in water under physiological conditions encompassed polymer hydrolysis an happened steadily within 3-10 d. The activity loss of entrapped alpha-chymotrypsin caused by loading and releasing depended on the method used for loading.
