Parallel printing

Dip-pen nanolithography (DPN) is a promising tool for depositing and patterning everything from proteins to polymers onto a surface. The materials to be patterned are contained in ‘inks’ and delivered using the tip of an atomic force microscope, in a manner similar to writing with a feather quill - but at a much smaller scale.
