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.

This study shows that gold coatings on subretinal implants cause retinal inflammation and neuronal loss, while platinum and titanium coatings reduce these effects, enabling better visual resolution implants.
