Abstract

A transdermal drug delivery patch and a method of controlling the drug release of the transdermal drug delivery patch by near-IR are disclosed. The transdermal drug delivery patch comprises a substrate, carriers and drugs. The drugs are encapsulated in the carriers, and the carriers having the drugs are disposed on a surface of the substrate. The carriers are formed of biodegradable polymers, and nano-particles with a photothermal conversion effect are loaded in the carrier. When the carriers are punctured into the skin and the nano-particles in the carrier absorb the near-IR, the near-IR is converted into heat by the nano-particles to melt the carrier and thus releasing the drugs encapsulated in the carrier into the skin. Accordingly, the speed of releasing the drugs encapsulated in the carrier can be controlled accurately by the near-IR.
