Diagnosing Alzheimer's disease using phototransistor, involves placing phototransistor in place, fixing cells on surface of channel layer, and sensing difference of photocurrents induced by cells

摘要

Method for diagnosing Alzheimer's disease using a phototransistor, involves (a) placing the phototransistor capable of sensing difference in level of photocurrents with respect to intensity of incident light, where the phototransistor comprises a channel layer, (b) fixing cells (300) on surface of the channel layer, and (c) sensing a difference of the photocurrents induced by the cells fixed on the channel layer to diagnose Alzheimer's disease.
