NUS researchers have developed a method to give more control to optogenetics, by using specially designed nanoparticles and nanoclusters (dubbed 'superballs'). These nanoparticles and superballs can emit different colours of light when excited by lasers at different wavelengths. The novel nanoparticles fluoresce either red or green depending on the energy of infrared light used to excite them. These different colours of light can then be used to trigger specific biological processes.
