New Method for Simple Fabrication of Microperforated Membranes

Microscopically porous polymer membranes have numerous applications in microfluidics, where they can act as filters, masks for surface patterning, and even as components in 3D devices. In the AIP journal Biomicrofluidics, chemist in Hong Kong describe a simple new method to fabricate free-standing polymer membranes with neatly patterned holes as small as 10 microns.
