Research on creation of photo-receptive device by using retinoids

我们研究了一种使用视黄醇(视黄酸、视黄酸和视黄醇)在人眼中创造一种实用的设备，这种设备对光的反应速度非常快，效率很高。这些功能都是在视蛋白的辅助下实现的。为了模拟这一机理，我们采用逐层自组装的方法制备了维甲酸和壳聚糖的层状单分子膜。实现了使用维甲酸的生物光子器件的光电流响应的外量子效率。

We have studied to create a practical device using retinoids (retinal, retinoic acid and retinol) in the human eyes which respond to light with extremely high speed and in high efficiency. These functions are realized by assist of opsin. In order to mimic this mechanism, we fabricated laminated mono-molecular film of retinoic acid and chitosan by using a layer-by-layer self-assembly process. The external quantum efficiency of the photocurrent response of biophotonic devices that use retinoids was realized.
