报告摘要:

Retinal degenerative diseases have devastating impacts on patient lives and with significant socioeconomic consequences. Attempts for treating the diseases by replacing the damaged photoreceptors attracted attention from both academia and medical professions. Here, we present the vertical Sinanowire photodetector array, embedded in flexible polymer, and the exploration of their retinal prosthesis applications. The Si nanowire photodetector arrays mimic biological rods photoreceptors morphologically and functionally, the packing density could be comparable or even exceed human rod photoreceptors, offering enhanced light absorption and sub-cell level retinal interface, as well as broad spectra response from UV to infrared (from 350 nm to 1050 nm), which is beyond the human vision perception. Si nanowire photodetectors offer significant potential as high-sensitivity artificial photoreceptors for treatments of retinal degenerative diseases.
