Micropatterning fluid membranes

An application of photolithographic patterning is described for producing a self‐assembled membrane that is fluid over some areas and immobilized or absent in others, as directed by the patterning on the support (see Figure). This is an important step towards forming a specific interface between living cells and silicon electronics. (Figure reprinted from Science 1997 275, 651–653; ©1997 AAAS)magnified image
