Abstract
The application relates to the technical field of analysis and detection, and discloses an echo wall mode sensor and a preparation method and application thereof. The echo wall mode sensor comprises a substrate and a fluorescent layer arranged on the substrate, and an inert layer is further arranged on the fluorescent layer; the fluorescent layer comprises an inner fluorescent layer and an outer fluorescent layer; the concentration of fluorescent dye in the inner fluorescent layer is 0.05-0.4 mg / mL; and the concentration of fluorescent dye in the outer fluorescent layer is 0.3-1.2 mg / mL. Through the technical scheme, the problems of low signal-to-noise ratio and poor displacement stability of an echo wall mode sensor based on fluorescent microspheres in the related art are solved.
