Abstract

Pen a nanoletter: Direct-write dip-pen nanolithography (DPN) has been used to generate protein nanostructures on modified silicon oxide surfaces. This technique offers control over feature size at the 50-550 nm scale. The bioactivity of the proteins remains intact and has been studied by fluorescence microscopy (see picture).
