제목 Smart Nanofibers for Biomedical Applications
초록 We are studying smart nanofibers for biomedical application such as cell capture and release aiming at cell container and cancer therapy. About the use for anticancer, self-heating and temperature-responsive nanofiber incorporated magnetic nanoparticles was developed because of their self-heating property by applying alternative magnetic field (AMF). Polymer composite nanofiber composed of poly (NIPAAm-co-HMAAm), MNPs and Doxorubicin were prepared by electrospinning followed by the cross-linking reaction. To test both thermotherapy and chemotherapy effects of composite nanofiber, the cytotoxicity to human melanoma cell line COLO 679 cells were evaluated. In case of DOX/MNP-nanofiber, cell viability decreased to 70% by AMF application. Although the thermotherapy effect itself showed a minor anticancer effect for a short duration AMF application, DOX released from the nanofibers induced the apoptosis of cancer cells due to a synergistic effect in combination with thermotherapy.
