Abstract
Microfluidic flow-through elements and methods for forming and using the same, particularly, low cost, easily sterilized, disposable microfluidic flow-through elements may include an orifice region suitable, for example, for fluid jet formation (such as in a droplet sorter or flow cell) or sample injection or hydrodynamic focusing (such as in a non-droplet flow cytometer). Laser drilling, for example laser ablation, may be used to form an orifice region extending through an orifice wall section of a base substrate. The base substrate may be unitarily-formed by injection molding a polymeric material. The orifice region may be advantageously configured to form a predetermined geometry by controlling the characteristics of the ablating beam.
