Abstract
The present invention relates to a method for effectively delivering an anticancer drug into cancer cells by binding the anticancer drug to pH-sensitive metal nanoparticles so as to be separated from cancer cells. The pH-sensitive metal nanoparticles according to the present invention may be heated by photothermal therapy, thereby effectively killing cancer cells in conjunction with the isolated anticancer drug.
