Abstract
Multiplexed patterns of hydrogels and phospholipids with fluorescent dyes are accomplished by dip-pen nanolithography® (DPN®). For example, four different dye-labeled hydrogel dot arrays are DPN® patterned within 50x50 μm2 area, and two different dye-doped phospholipids dots and letters with less than 1 μm line-width are also DPN® patterned. We demonstrate that multiink patterns with precise alignment are able to be printed by DPN® within a micron-scale. Moreover, this multi-ink DPN® patterning methodology can be extended to delicate bio-materials printing in a subcellular scale with accurate positioning control.
