Abstract
A biosensor apparatus is provided. The biosensor apparatus includes a base substrate; a first fluid channel layer on the base substrate and having a first fluid channel passing therethrough; a foundation layer on a side of the first fluid channel layer away from the base substrate, a foundation layer throughhole extending through the foundation layer to connect to the first fluid channel; and a micropore layer on a side of the foundation layer away from the base substrate, a micropore extending through the micropore layer to connect to the first fluid channel through the foundation layer throughhole. The micropore layer extends into the foundation layer throughhole and at least partially covers an inner wall of the foundation layer throughhole.
