Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="ppap201400169-sec-0001" sec-type="section"> <p>In the present work, for the first time, nano‐thick peptidomimetic coatings were developed using a LP inductively excited pulsed plasma polymerization of 2‐ethyl‐2‐oxazoline (ppEtOz) to control the cell‐surface interactions for biological applications. The different ppEtOz coated surfaces were investigated by FTIR‐ATR, XPS, Ellipsometric, and WCA analysis. Using Gaussian deconvolution method for IR spectra, we compared the modifications obtained in the chemical compositions for ppEtOz coated samples obtained under different plasma parameters. It was found that the amide I/amide II ratios decreased as the effective plasma power increased, which in turn decreased the surface hydrophilicity for ppEtOz coatings. Cell repellent properties of the ppEtOz coatings deposited at P_eff=1 W and 2.5 W were achieved.<inline-graphic xlink:href="ark:/27927/pgj11pxfd3v" content-type="ppap201400169-gra-0001" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </sec> </abstract>
