Microfluidic chip for focusing a stream of fluid containing particulates

摘要

A microfluidic chip for focusing a stream of fluid containing particulates has a sample microfluidic channel configured to receive the stream of fluid containing particulates and a polygonal cross-sectional area, and the stream of inductive fluid is Formed by merging the sample microfluidic channel and the inductive 10 microfluidic channel at an oblique angle along only part of the inductive microfluidic channel configured to receive and one or more sides of the inductive microfluidic channel And a common microfluidic channel having a detection zone disposed in a common microfluidic channel, the polygonal section having a cross section and the one or more sensors. The merging of the sample microfluidic channel and the inductive microfluidic channel provides a composite fluid stream comprising a focused beam of microparticles asymmetrically disposed in the common microfluidic channel 15 adjacent to a corner or side of the common microfluidic channel As configured, the one or more sensors are configured to sense properties of the focused beam of particles in the common channel.
