Dip-Pen Nanolithography (DPN) and Related Techniques

Our group focuses on the advancement and application of dip-pen nanolithography and related techniques like polymer pen lithography (PPL) for the site-specific chemical and bio-chemical modification of surfaces and devices.

Our Research Topics

Our research is aimed at the advancement and application of Scanning Proble Lithography (SPL) methods, in particular Dip-Pen Nanolithography (DPN) and related methods like e.g. Polymer Pen Lithography (PPL) and Microchannel Cantilever Spotting (µCS).

These SPL methods are versatile tools, combining many advantages of electron beam lithography, inkjet printing and microcontact printing in relation to resolution, integration and throughput. These methods are of particular interest when working with sensitive biological materials, since they work at mild process parameters and need no lift off processes (with the associated solvents or etching processes). Furthermore, the methods allows for "multiplexing", i.e. the parallel application of different inks within a pattern.
