제목 NIR light-triggered drug release using biodegradable polymer fibers incorporated with indocyanine green and phase-changeable fatty acid for localized anti-cancer therapy
초록 This study introduces a new system for NIR light-triggered release of drugs. The system consists of polycaprolactone (PCL)-based fibers havings a core loaded with doxorubicin (DOX) and a sheath incorporated with indocyanine green (ICG) as a NIR-absorbing agent together with a phase-changeable fatty acid. Upon NIR irradiation, the photothermal agent will generate heat to raise the local temperature of the fibers. When the temperature is above the melting point of the fatty acids, nano-pores will be generated in the fibers. This response to NIR irradiation allows the instant release of DOX from the fibers through the pores, leading to the significant increase of anticancer activity in combination with the hyperthermia effect arising from the photothermal agent.
