PEM anchorage on titanium using catechol grafting.

<h4>Background</h4>This study deals with the anchorage of polyelectrolyte films onto titanium surfaces via a cathecol-based linker for biomedical applications.<h4>Methodology</h4>The following study uses a molecule functionalized with a catechol and a carboxylic acid: 3-(3,4-...
