We have used friction force microscopy to study the boundary friction of thiophenol and 2-napthalenethiol monolayers on gold. The strength of the adhesion was altered by working in dry N2 gas or in ethanol. A contact mechanics model developed by Sridhar, Johnson and Fleck1,2 (SJF) for a thin, compliant elastic film confined between stiffer substrates was used to evaluate the data in systems with higher adhesion.

Plasma treatment is one of the most promising tools to control surface properties of materials tailored for biomedical application. Among a variety of processing conditions, such as the nature of the working gas and time of treatment, discharge type is rarely studied, because it is mainly fixed by equipment used. This study aimed to investigate the effect of discharge type (direct vs. alternated current) using air as the working gas on plasma treatment of poly(ethylene terephthalate) films, in terms of their surface chemical structure, morphology and properties using X-ray photoelectron spectroscopy, scanning electron microscopy, atomic force microscopy and contact angle measurements. The effect of the observed changes in terms of subsequent chitosan immobilization on plasma-treated films was also evaluated. The ability of native, plasma-treated and chitosan-coated films to support adhesion and growth of mesenchymal stem cells was studied to determine the practicability of this approach for the biomedical application of poly(ethylene terephthalate) films.
