Abstract

Microfluidic focusing of particles, control over the positions of particles in a focused stream, may serve as a necessary step for the downstream processing, such as detection, counting and separation. Here, we demonstrated the focusing of polystyrene particles (PS) and live cells at low Reynolds numbers (Re < 0.2) in a microfluidic channel with open v-shaped microstructures achieved by femtosecond pulse (fs) laser micromachining. The developed microfluidic chip is hoped to be integrated with detection components, such as contact imaging and fluorescence lifetime-resolved imaging, where particle focusing at a relatively low flow rate is required.
