Abstract: Disclosed herein are methods of making micropores of a desired height and/or width between two isotropic wet etched features in a substrate which comprises single-level isotropic wet etching the two features using an etchant and a mask distance that is less than 2X a set etch depth. Also disclosed herein are methods using the micropores and microfluidic devices comprising the micropores.

Abstract: Disclosed herein are methods of immobilizing a particle which comprise focusing the flow of a sample fluid containing the particle into a virtual channel which flows towards an unoccupied hydrodynamic trap in a microfluidic channel such that the particle flows into the hydrodynamic trap and becomes immobilized therein. Also disclosed are microfluidic devices which comprise at least one microchannel having at least one hydrodynamic trap, at least one focusing fluid inlet, said focusing fluid inlet is upstream of the hydrodynamic trap such that a focusing fluid introduced therein results in a virtual channel of a sample fluid when present which preferentially flows toward the hydrodynamic trap.
