Abstract

A color-sensitive image sensor with embedded microfluidics includes a silicon substrate having (a) at least one recess partly defining at least one embedded microfluidic channel and (b) a plurality of photosensitive regions for generating position-sensitive electrical signals in response to light from the at least one recess, wherein at least two of the photosensitive regions are respectively located at at least two mutually different depth ranges, relative to the at least one recess, to provide color information. A wafer-level manufacturing method produces a plurality of such color-sensitive image sensors. A method for generating a color image of a fluidic sample includes performing imaging, onto a plurality of photosensitive regions of a silicon substrate, of a fluidic sample deposited in a microfluidic channel embedded in the silicon substrate, and generating color information based upon penetration depth of light into the silicon substrate.
