Creating nanoscale patterns of dendrimers on silicon surfaces with dip-pen nanolithography

Dip-pen nanolithography (DPN) is a nanowriting procedure that employs an AFM tip as a nanopen to deposit organic molecules onto a substrate surface. This paper describes the application of DPN to write with dendrimer inks. We have generated patterns with 100 nm features (similar to20 dendrimer molecules) on a Si/SiOx surface and investigated how the resolution is affected by surface chemistry and molecular weight of the dendrimer ink.
