Abstract

The bioactive glasses (BGs)/Cisplatin and magnetic bioactive glasses (MBGs)/Cisplatin were doped into the chitosan (CS)-grafted- poly (ε-caprolactone) (PCL) nanofibers for controlled release of Cisplatin under various pH values and temperatures. The simultaneous effect of chemotherapy and hyperthermia was investigated against MG-63 osteosarcoma cells by treating of cells with Cs-g-PCL/MBGs/Cisplatin under an alternating magnetic field. The synthesized nanofibers were characterized using XRD, FTIR, 1H NMR, SEM, and EDX analysis. The bioactivity, and drug loading efficiency of fibers were investigated. There was no initial burst release of Cisplatin from BGs/Cisplatin and MBGs/Cisplatin loaded Cs-g-PCL/MBGs nanofibers and the Cisplatin release rate was accelerated under pH of 5.5 and temperature of 43 °C compared with physiological condition. The apoptotic/necrotic effect indicated that 100 μg mL−1 nanofibers was optimum for killing of MG-63 cells. The future researches could be focused on the application of nanofibers as an implantable device next to a bone tumor for bone cancer therapy in vivo.
