Abstract
(Figure Presented) DPN benefits mCP: The intrinsic drawbacks in conventional microcontact printing, that is, roof collapse and lateral ink diffusion, were addressed by using topographically flat, chemically patterned PDMS stamps made by dip-pen nanolithography. The chemically patterned flat stamps were used for contact printing of various inks including thiols, proteins and hydrophilic dyes. The as-made features can reach sub-100 nm resolution and a very low filling factor
