: The phospholipid 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) can be used as an ink for noncovalent patterning on a variety of surfaces under humidity-controlled conditions. Simultaneous writing of different inks gives aligned, multilayer phospholipid patterns (see fluorescence image; scale bar=5 μm). These patterns are stable on some surfaces in water, while on others they can spread to form supported lipid bilayer membranes.
