Biosensor analysis technology is a kind of technology with high specificity that can convert biological reactions into optical and electrical signals.In the development of drugs for Alzheimer's disease(AD),according to different disease hypotheses and targets,this technology plays an important role in confirming targets and screening active compounds.This paper briefly describes the pathogenesis of AD and the current situation of therapeutic drugs,introduces three biosensor analysis techniques commonly used in the discovery of AD drugs,such as surface plasmon resonance(SPR),biolayer interferometry(BLI)and fluorescence analysis technology,explains its basic principle and application progress,and summarizes their advantages and limitations respectively.
