Abstract
A microfluidic apparatus is provided. The microfluidic apparatus includes a first substrate; a microfluidic layer on the first substrate and defining a microfluidic channel, wherein the first substrate having a first side closer to the microfluidic layer, and a second side away from the microfluidic layer, the first side and the second side opposite each other; a plurality of detectors on a side of the microfluidic channel away from the first substrate; a unitary grating plate on the second side of the first substrate and including a plurality of grating blocks of different wavelength selectivity; and a light extraction layer including a plurality of light extractors on the first side of the first substrate and configured to extract light diffracted by the plurality of grating blocks out of the first substrate.
