Controllable Synthesis, Photothermal Conversion and in vitro Photothermal Therapy of Gold Nanostars/Nanobipyramids
摘要
Abstract
Using seed-growth method,gold nanostars and gold nanobipyramids were synthesized,re-spectively,and they were characterized by transmission electron microscope and ultraviolet-visible (UV-Vis) spectrophotometer. Moreover,the photothermal conversion,biocompatibility and in vitro photothermal therapy(PTT) of gold nanostars and gold nanobipyramids were evaluated. The results show that the UV-Vis absorption peaks of gold nanostars and gold nanobipyramids are located at about 808 nm and 815 nm,and the photothermal conversion efficiency is calculated to be 48.43% and 53.68%. The cell experiments indicate that the gold nanostars and gold nanobipyramids have good biocompatibility,and the viabilities of MCF-7 cells incubate with gold nanostars and gold nano-bipyramids are decreased to be about 22.54% and 13.73%,after they are irradiated by 808 nm la-ser for 5 min, respectively. Furthermore, compared with the gold nanostars, the gold nanobipyra-mids have more excellent PTT performance,which could be good candidate as safe and high-efficient nanoprobe material for PTT in tumors.关键词
