This paper develops biomimetic scaffolds to mimic human subretinal debris in animal models, improving the accuracy of preclinical testing for subretinal prostheses.

The paper develops biocompatible coatings for 3D electrodes on retinal prostheses using electrodeposition and photolithography to protect gold surfaces while preserving functionality.

The paper develops doped amorphous silicon resistors for photovoltaic retinal implants, enabling smaller pixel sizes and improved electric field contrast without reducing photoresponsivity.

This study upgrades a subretinal photovoltaic implant in rats, improving visual acuity from 100m to 28m pixels.

This study evaluates long-term biocompatibility and performance of 3D honeycomb-shaped subretinal implants in rats, showing improved stimulation thresholds compared to flat designs.

This paper develops 3D electroplated structures for subretinal prostheses to improve electric field penetration and stimulation efficiency in retinal implants.

The paper demonstrates that retinal neurons migrate into honeycomb-shaped wells of a subretinal prosthesis, enabling selective stimulation of second-order neurons without affecting electrical excitability or causing additional glial stress.
