Light on a nanoscale: channelling energy through space and time to control neuronal activity

点击翻译按钮获取中文摘要

Quantum-mechanical effects of energy transfer and resonance will be harnessed to yield ultrabright nanoscale light sources. Research will unveil the intricate interplay between energy harvesting, transferring and emitting centres designed so that the flow of energy exhibits a directed character. This focussed intense energy will produce abundant visible photons from infrared light. Genetically engineered cells able to be stimulated optically by using an optogenetics method will be illuminated by our nanoscale light causing modulation of cell activity. This new capability will enable remote control of neuronal activity in specific circuits within the nervous system without the limitation of surgically inserted optical fibres.
