Enhancement of Polymer Cytocompatibility by Nanostructuring of Polymer Surface

Figure 2

Dependence of the contact angle on the plasma exposure time for pristine PE, plasma-treated PE (PE/plasma), plasma-treated and Au nanoparticle-grafted PE (PE/plasma/Au), plasma-treated and biphenyldithiol-grafted PE (PE/plasma/bi), and plasma-treated and biphenyldithiol- and Au nanoparticle-grafted PE (PE/plasma/bi/Au). The measurement was accomplished 20 days after the plasma modification [7].
