Dip Pen Nanolithography (R) (DPN (TM)) is the controlled delivery of material from nanoscale tips to a surface. Its advantages over other lithography techniques include low operating costs, high resolution, nanoscale registry and multiplexed deposition capabilities. With NanoInk's latest nanolithography tools and new biocompatible patterning protocols, any scientist can easily and rapidly create arbitrary hydrogel patterns with subcellular feature sizes to be used for cell adhesion, cell migration and drug delivery studies.
