20.500.12556/RUL-131280 Influence of polyelectrolyte multilayer properties on bacterial adhesion capacity Bacterial adhesion can be controlled by different material surface properties, such as surface charge, on which we concentrate in our study. We use a silica surface on which poly(allylamine hydrochloride)/sodium poly(4-styrenesulfonate) (PAH/PSS) polyelectrolyte multilayers were formed. The corresponding surface roughness and hydrophobicity were determined by atomic force microscopy and tensiometry. The surface charge was examined by the zeta potential measurements of silica particles covered with polyelectrolyte multilayers, whereby ionic strength and polyelectrolyte concentrations significantly influenced the build-up process. For adhesion experiments, we used the bacterium Pseudomonas aeruginosa. The extent of adhered bacteria on the surface was determined by scanning electron microscopy. The results showed that the extent of adhered bacteria mostly depends on the type of terminating polyelectrolyte layer, since relatively low differences in surface roughness and hydrophobicity were obtained. In the case of polyelectrolyte multilayers terminating with a positively charged layer, bacterial adhesion was more pronounced than in the case when the polyelectrolyte layer was negatively charged. bacterial adhesion Pseudomonas aeruginosa polyelectrolyte multilayers poly(allylamine hydrochloride) poly(4-styrenesulfonate) scanning electron microscopy zeta potential true false true Angleški jezik Ni določen Članek v reviji 2021-09-24 14:35:41 2021-09-24 14:35:42 2022-09-10 04:11:06 0000-00-00 00:00:00 2016 0 0 12 str. iss. 10, art. 345 Vol. 8 2016 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 53 2073-4360 10.3390/polym8100345 29783591 RAZ_Kovacevic_Davor_2016.pdf RAZ_Kovacevic_Davor_2016.pdf 1 514A200BBB6FD2296C0F134E2D1230E1 030ab59aa45dca04295bd841a6fe442be56334ac60ead304b6233c7e43b6c084 0cd005df-1d34-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=148588 http://www.mdpi.com/2073-4360/8/10/345 1 a8cc4168-1d33-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=148587 Zdravstvena fakulteta 0 0 0
