摘要

本研究报道了一种可以模拟感光细胞功能的视网膜下植入装置。芯片上的光电二极管(PD)阵列根据光的强度将入射光转换成电流。在每个光电二极管的末端都有一个电极，pd将电流转移到剩余的健康视觉细胞，如双极细胞和水平细胞，然后激活这些细胞。测试了材料和人工光感受器本身的生物相容性，并对模拟条件下芯片的光电特性进行了描述和讨论。

Subretinal implantable artificial photoreceptor

The present study reports a subretinal implant device which can imitate the function of photoreceptor cells. Photodiode (PD) arrays on the chip translate the incident light into current according to the intensity of light. With an electrode at the end of every photodiode, the PDs transfer the current to the remnant healthy visual cells such as bipolar cells and horizontal cells and then activate these cells. Biocompatible character of the materials and artificial photoreceptor itself were tested and the photoelectric characteristics of the chips in simulative condition were described and discussed.
