Neurostimulation: Direct Electrical Neurostimulation with Organic Pigment Photocapacitors (Adv. Mater. 25/2018)

Organic electrolytic photocapacitors transduce light pulses into localized displacement currents that electrically stimulate neurons. These nanoscale devices are freestanding, requiring no wiring, and are stable in physiological conditions. In article number 1707292, Yael Hanein, Eric Daniel Głowacki, and co-workers successfully photostimulate cultured neurons and light-insensitive explanted retinas, paving the way for minimally invasive retinal prosthetics.
