Problems solved by technology

However, Fresnel lenses, microlenses, and brightness enhancing films (BEFs) are not spectrally selective enough to collect only the emitted light, thus also increasing the noise intensity from the excitation light

Abstract

A biosensor is provided. The biosensor includes a sensing element and a cover disposed on the sensing element. The sensing element includes: a first substrate embedded with a photodiode; and a filter layer disposed on the substrate. The cover includes: a second substrate; an upper optical element disposed in the second substrate; and an upper reaction well disposed on the upper optical element.

Description

technical field [0001] Embodiments of the present invention relate to a biosensor, in particular to a biosensor with a focusing element or a focusing structure. Background technique [0002] Recently, CMOS image sensors have been used for biological or biochemical detection. For this application, fluorescent molecules serve as reporters and labels on biological or biochemical samples. A biological or biochemical sample can be placed on the photodiode, and the fluorescence emitted by the biological or biochemical sample can be directed to the photodiode to decode the biological signal based on a predetermined workflow or algorithm. Fluorescence signals generally require shorter wavelength excitation light to produce longer wavelength emission light signals. Therefore, appropriate optical components may be necessary to block the excitation light of shorter wavelengths from entering the photodiode in order to discriminate weak emitted light signals with longer wavelengths. A...
