제목 Integration of superparamagnetic iron oxide nanoparticles and polyaspartamide for hyperthermia therapy
초록 We report a delicate synthesis process of polyaspartamide-encapsulated superparamagnetic iron oxide nanoparticles (PA-SPIONs) for hyperthermia application. SPIONs with a high magnetization have been applied as nano-heaters while PA is a biocompatible and biodegradable polymer with a polysuccinimide (PSI) backbone. Multi-functional polymer PA could be conjugated with other groups such as biotin to enhance the uptake capability by receptors of cancer cells. Consequently, encapsulating SPIONs nano-heaters with PA biopolymer is an attractive roadmap for hyperthermia therapy application. Our results revealed that PA-SPIONs showed excellent biocompatible behavior based on cell viability test. With Prussian blue staining of cancer cells (4T1), cellular uptake of PA-SPIONs was significantly increased in the presence of biotin conjugated on the outer shell. Furthermore, PA-SPIONs exhibited effective cancer killing activities in both in vitro and in vivo hyperthermia experiments.
