제목 Magnetic Nanoparticle-Conjugated Polymeric Micelles for Combined Hyperthermia and Chemotherapy
초록 Magnetic nanoparticles-conjugated polymeric micelles (MNPs-PMs) consisting of poly(ethylene glycol)-poly(lactide) (PEG-PLA) and iron oxide nanoparticles were prepared and used as nanocarriers for combined hyperthermia and chemotherapy. Doxorubicin was encapsulated in MNPs-PMs, and an alternating magnetic field (AMF) resulted in an increase to moderately increased temperature in a suitable range for inducing hyperthermia and a higher rate of drug release than observed without AMF. In vitro cytotoxicity and hyperthermia studies were carried out using human lung adenocarcinoma A549 cells. When MNPs-PMs encapsulated with an anticancer drug were used to treat A549 cells in combination with hyperthermia under AMF, the 78% of the cells were killed by the double effects of heat and the drug, and the combination was more effective than either chemotherapy or hyperthermia alone. Therefore, MNPs-PMs encapsulated with an anticancer drug show potential for combined chemotherapy and hyperthermia.
