DESCRIPTION:We report on development of ultrathin optoelectronic devices f
 or stimulating biophysical processes. All of these devices rely on near in
 frared irradiation in the tissue transparency window to actuate nanoscale 
 organic semiconductor components. Our flagship technology is the photocapa
 citor – a device that mimics biphasic current-pulse neurostimulation and
  thus transduces an optical signal into directly-evoked action potentials 
 in neurons. The devices operate in the tissue transparency window of the n
 ear-infrared\, where light can penetrate deeply through the skin and bone.
  The motivation is to provide a wireless and minimalistic implant which ca
 n perform the duty of standard implantable electrodes\, but without wiring
 . The devices we fabricate are not only wireless but also 100-1000 times t
 hinner than most existing technologies. Making implants have as small as p
 ossible mechanical footprint improves the efficacy of bioelectronics medic
 al treatments by minimizing the risk for inflammation and making surgical 
 implantation less invasive. Our to-date work has focused on optimizing the
 se devices using single-cell electrophysiology models and retinal explants
