New technology for drug delivery using light

Scientists at Pohang University of Science and Technology have proposed a new concept for non-invasive drug delivery. The system releases the drug by shining safe infrared light onto the surface of the skin.  This is reported by Phys.org.

The researchers have come up with an alternative solution for patients who have to take daily injections to control chronic diseases such as diabetes.  

Injections or light irradiation? To generate photovoltaic energy using infrared light that can penetrate the skin, the specialists suggested using conversion-enhancing nanoparticles. As a result of this exposure, the special film that seals the drug substance melts and the drug enters the body. 

Although the technology is presented only as a concept, one of the lead authors of the study, Professor Sei Kwang Han believes that it will contribute to the design and development of new phototherapy technologies using implantable medical devices.
