A new method to characterize chemically and topographically nanopatterned surfaces

J Biotechnol. 2006 Nov 1;126(2):196-204. doi: 10.1016/j.jbiotec.2006.04.036. Epub 2006 Jun 23.

Abstract

Surface chemistry of topographically patterned grooved samples with ridges of 150 nm width, adsorbed with self-assembled monolayers (SAMs) of alkanethiols on gold, have been characterized by near edge X-ray absorption fine structure (NEXAFS) spectroscopy. Analysis reveals that NEXAFS may discriminate between different chemistries adsorbed to the tops, sidewalls and grooves of the patterns.
