Researchers develop near-infrared light triggered drug delivery system


Researchers develop near-infrared light triggered drug delivery system
A new concept of on-demand drug delivery system has emerged in which the drugs are automatically released from in vivo medical devices simply by shining light on the skin.
A research team led by Professor Sei Kwang Hahn of the Department of Materials Science and Engineering and Professor Kilwon Cho of the Department of Chemical Engineering at POSTECH have together developed an on-demand drug delivery system (DDS) using an organic photovoltaic cell coated with upconversion nanoparticles. This newly developed DDS allows nanoparticles to convert skin-penetrating near-infrared (NIR) light into visible light so that drug release can be controlled in medical devices installed in the body. These research findings were published in ....
