Fluid-matter interaction in DLD structures

This research involves the fabrication of microfluidic devices, especially for blood plasma separation. The manufacturing techniques explored here are ultra short pulsed laser micromachining, photolithography, Deep reactive ion etching and hybrid machining technique comprising of micromilling and electropolishing,  Deterministic lateral displacement is observed in the fluid flow between the micropillars fabricated in the microchannels. This is useful in the separation of blood particles from plasma. Further, the effect of the fluid forces on the bending of the micropillars is studied with the major focus on the critical diameter of the particles being separated.
