New nanoparticles can adjust the beating speed of heart cells by emitting different colours of light. Light from nanoparticle clusters was also able to activate anticancer drugs within cells NATIONAL UNIVERSITY OF SINGAPORE The biological technique of ‘optogenetics’ uses light to control cells within living tissues that have been genetically modified to be light-sensitive. However, deeply penetrating light is often needed to activate the...
