Understanding brain functions using upconversion nanoparticles

(National University of Singapore) Scientists from the National University of Singapore (NUS) have worked with an international research team to jointly develop a novel approach for deep brain stimulation. The new method utilises upconversion nanoparticles developed by Professor Liu Xiaogang from the Department of Chemistry at NUS Faculty of Science to allow delivery of visible light deep into the brain to stimulate neural activities in a less-invasive manner. This innovation marks a significant
