Covalently bound monolayer patterns obtained by plasma etching on glass surfaces

Abstract

Micropatterns of β-cyclodextrin (β-CD) monolayers on glass are obtained by using a plasma etching approach with polydimethylsiloxane (PDMS) stamps. This simple and versatile approach provides a promising alternative to current techniques for creating patterns of covalently bound molecules. It is also possible to fabricate sub-10 μm sized features.
