Abstract:
A microfluidic device for analyzing particles dispersed in a sample fluid, comprising:a first inlet fluidically coupled to a first channel for introduction of the sample fluid; a second inlet fluidically coupled to a second channel for introduction of a first reagent fluid; a reactor channel fluidically coupled to the first channel and the second channel such that the sample fluid is focused into a thin ribbon between two streams of the first reagent fluid, the reactor channel having a length sufficient to allow a chemical reaction between the sample fluid and the first reagent fluid; a third inlet fluidically coupled to a third channel for introduction of a sheath fluid; a cytometer channel fluidically coupled to the reactor channel and the third channel such that the sample fluid is focused into a single file stream of particles between two streams of the sheath fluid; and a detection region.
