title: An anti-clogging 3D porous membrane for sorting and patterning of micro-entities.
abstract: A 3D porous membrane containing pyramidal microstructures around funnel-like pores is demonstrated as a unique anti-clogging porous membrane for high efficiency sorting and patterning of cells/beads. The membrane exhibits four interesting features: anti-clogging, patterning of micro-entities of different sizes, bi-directional separation and simultaneous separation and patterning of micro-entities.
