This glass flow-focusing microfluidic chip has three inlets and one outlet. It is designed to focus the central flow by using the two side flow streams. The hydrodynamic focusing can facilitate rapid mixing as a micro-reactor to study micro-scale reactions and processes or as a mean to confine particles (cells) aligned in a single file in sample stream. The advantages include small volumes, rapid mixing, no sample dispersion, no cross-contamination, and well-maintained conditions.
