Artificial bilayer lipid membranes (BLMs) on-chip for single molecule sensing

A polymer microfluidic device for the formation of artificial bilayer lipid membranes (BLMs) on-chip is described. The device is fabricated from thin, transparent films of poly(methyl methacrylate), allowing for optical monitoring of the BLM. In addition, detection of single fluorescently-labeled lipid molecules using conventional epifluorescence microscopy is described
