On-demand drug release

摘要

Drug-carrying nanoparticles that shrink and release their payload when irradiated with ultraviolet (UV) light could offer a way to get drugs deep into tissues and to unleash them on demand. This could be a valuable therapeutic tool for diseases such as cancer. Currently available drug-delivering nanoparticles are at least 100 nanometres in diameter, which makes it difficult for them to squeeze into tumours.
