摘要：
A drug and a biodegradable polymer having at least one carboxyl group are encapsulated into nanoparticle which is formed by a block copolymer having a hydrophilic segment and a hydrophobic segment. This invention thus provides a drug-encapsulated nanoparticle which shows an increased in vivo drug-stability.
