Abstract

Nanowires have served as a transformative platform for advanced neural and tissue interfaces. While their photovoltaic properties hold exceptional promise for neural modulation, existing photostimulation approaches predominantly rely on visible light–activated photoelectrochemical mechanisms. Here, we present a solution-processed photovoltaic nanoassembly comprising a ZnO nanowire array sensitized with AgBiS 2 nanocrystals that enables efficient near-infrared (NIR) neural stimulation through capacitive photocurrents. By optimizing nanowire morphology and nanocrystal interdigitation, the platform achieves high charge injection densities (tens of microcoulombs per square centimeter) at low NIR intensities (
