The ability of microorganisms to 'recognise' a change in the hydrophobicity/hydrophilicity balance of the surface was demonstrated using thermoresponsive poly(N-isopropylacrylamide) co-polymers with different Lower Critical Solution Temperatures. The polymers were grafted onto hydrolysed glass under well controlled conditions and the adhesion was followed using C-13-labelled Listeria monocytogenes. Attachment of the bacteria was found to be directly affected by the polymer transition from a hydrophilic to a hydrophobic state but by less than one order of magnitude.
