Abstract
A biosensor for detecting light signals emitted by a biological material is provided. The biosensor includes a light signal detector which comprises an array of light sensor pixels. The biosensor further includes a light signal filter layer disposed on a surface of the light sensor pixel array, a metal nanometer light focusing unit array layer, a grating array layer which comprises micro-gratings, and a biological material sample bearing area which comprises a plurality of sample gathering units. Each sample gathering unit aligns with one micro-grating and one metal nanometer light focusing unit in the vertical direction, and at least one of the light sensor pixels.
