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 Nano Energy on March 1, 2021.

 

"The combination of a flexible photovoltaic cell and a drug delivery system enables on-demand drug release using light," explained Professor Sei Kwang Hahn. "The drug delivery system is activated using near-infrared light that is harmless to the human body and is highly skin-penetrating."

 

He added, "Since this enables nimble control of drug release of medical devices inserted into the body by using near-infrared light, it is highly anticipated to contribute to the development of phototherapy technology using implantable medical devices."
