Abstract:
1. A temperature-sensitive nano-carrier comprising a water-soluble polymer crosslinked through a photo-crosslinkable functional group at the end of the polymer, wherein the temperature-sensitive nano-carrier has a nanoparticulate form and pores in which said nano-carrier is capable of encapsulating materials, wherein the average diameter of the polymer changes depending on temperature, wherein the diameter of the temperature-sensitive nano-carrier is between 50 and 500 nm, and wherein the pore size of the temperature-sensitive nano-carrier at 37° C. is between 3 and 20 nm, wherein the photo-crosslinkable functional group is at least one of coumarin, thymine or cinnamate, and the polymer has a nanoparticulate form.
