"Biofouling, the undesired colonization of surfaces, is a major\r\nproblem for marine-related industries. To prevent unwanted effects caused by\r\nbiofouling, suitable non-toxic coatings for the marine environment are required.\r\nConditioning, i.e. the adsorption of proteins and macromolecules influences, as\r\nsurface chemistry and morphology do, the settlement of fouling oragnisms. Investigating\r\nthe temporal dynamics of conditioning film formation on functionalized\r\nself assembled monolayers (SAMs), it was shown that the obtained film thickness\r\nof about 10Å to 20Å is independent of the surface chemistry but differences\r\noccur concerning the composition of these films. While on hydrophilic surfaces\r\nmore proteinaceous compounds are detectable, the hydrophobic surfaces show a\r\nlower intensity of proteins. Furthermore, is was shown that in standard Ulva linza\r\nspore settlement assays the influence of a molecular conditioning layer is likely\r\nto be small, but by increasing pre-conditioning time this influence gains importance\r\nand should be considered in long term experiments. Preconditioning also\r\nresulted in detectable surface differences in field studies. It was found that preconditioned\r\nsamples which contain more proteinaceous compounds seem to be more\r\nattractive for settlement. Experiments with matured laboratory biofilms formed\r\nby Pseudomonas aeruginosa demonstrated that using a protein-rich medium results\r\nin conditioning film formation. Conversely, surface conditioning is reduced\r\nwhen a media containing a smaller amount of proteins is utilized. Furthermore,\r\nit was observed that surface chemistry has no remarkable effect on the fraction\r\nof inoculated bacteria that adhere to a surface.\r\nFinally, inspired by the nanostructured skin of dolphins, electron-beam lithography\r\nwas utilized to create a honeycomb topography made of poly(N-isopropylacrylamide)\r\n(PNIPAM). The evaluation showed that structures from 0.75 μm to\r\n2.5 μm in diameter reduce Ulva settlement in comparison to a smooth PNIPAM\r\nsurface. It should be noted, that wet polymer structure heights in the range of\r\nonly 0.01 μm do have an effect on spores with a body size of around 5 μm."^^ . "2013" . . . . . . . "Isabel"^^ . "Thome"^^ .
