Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

We report the first direct patterning of elastomeric PDMS structures by dip-pen nanolithography (DPN). This method involves the use of a cantilever tip to transfer a PDMS ink onto a silicon dioxide surface to create dot array patterns which are then cross-linked and bonded irreversibly to the substrate. The chemical composition of the PDMS structures deposited by DPN was characterised by Raman microspectroscopy to provide an insight into the ink transfer process. This technique offers a significant advance in the ability to rapidly and easily produce programmable surface features from a widely used polymer for use in a variety of applications.
