Microfluidic chip and microfluidic system

Abstract

The present disclosure provides a microfluidic chip and a microfluidic system. The microfluidic chip includes: a droplet flow passage; at least two grating regions that are disposed along a length direction of the droplet flow channel and have different grating constants; a light source disposed at a first end of the droplet flow channel along the length direction of the droplet flow channel and configured to provide incident light rays of different wavelengths; and a wavelength detector used to detect reflected light rays or transmitted light rays of the incident light rays passing through the at least two grating regions.

Dependencies are inferred from the claim text.
