Focusing of sample cells or particles to a single-particle stream in miniature flow cytometers is achieved using pressure-driven hydrodynamic focusing in microfluidic channels. Hydrodynamic focusing models predict the focused sample stream width in the low Reynolds number regime (Re 1) of the Navier...
