“…The interactions between the substrate and particulate contaminants need to be better understood in order to reduce equipment fouling, to improve the efficiency of cleaning and disinfection, or to develop easy-to-clean surfaces (Podczeck, 1999). Chemical compounds present in food and pharmaceutical mixtures may influence interactions with surfaces and adhesion processes (Speranza et al, 2004). Proteins at the outer surface of bacteria are known to play an important role in the initial attachment to solid surfaces in water (Dufrêne et al, 1996;Flint et al, 1997;Caccavo, 1999;Boonaert and Rouxhet, 2000;Lower et al, 2005;Mercier-Bonin et al, 2009).…”

AbbreviationsBSA: bovine serum albumin RFC: radial flow cell XPS: X-ray photoelectron spectroscopy 2 ABSTRACTThe influence of substrate hydrophobicity and biomacromolecules (dextran, bovine serum albumin -BSA) adsorption on the cleanability of surfaces soiled by spraying aqueous suspensions of quartz particles (10 to 30 µm size), then dried, was investigated using glass and polystyrene as substrates. The cleanability was evaluated using radial flow cell (RFC).The surface composition was determined by X-ray photoelectron spectroscopy (XPS). The interpretation of XPS data allowed the complexity due to the ubiquitous presence of organic contaminants to be coped with, and the surface composition to be expressed in terms of both the amount of adlayer and the mass concentration of adlayer constituents.When soiled with a suspension of particles in water, glass was much less cleanable than polystyrene, which was attributed to its much lower water contact angle, in agreement with previous observations on starch soil. Dextran was easily desorbed and did not affect the cleanability. The presence of BSA at the interface strongly improved the cleanability of glass while the contact angle did not change appreciably. In contrast, soiling polystyrene with quartz particles suspended in a BSA solution instead of water did not change markedly the cleanability, while the contact angle was much lower and the aggregates of soiling particles were more flat. These observations are explained by the major role of capillary forces developed upon drying, which influence the closeness of the contact between the soiling particles and the substrate and, thereby, the adherence of particles. The capillary forces are proportional to the liquid surface tension and depend in a more complex way on contact angles of the particles and of the substrate. The dependence of cleanability on capillary forces, and in particular on the liquid surface tension, is predominant as compared with its dependence on the size and shape of the soiling aggregates, which influence the efficiency of shear forces exerted by the flowing water upon cleaning.

“…Various strains of bacteria are capable of adherence and proliferation on biomedical polymers leading to serious nosocomial contaminations [1,2]. In this situation, the implant has to be taken away because of the poor success of the treatment; hence, much emphasis has been laid on practical ways to thwart device-related infections via delivering anti-infective polymeric implants [3].…”

A B S T R A C TMedical-grade polyvinyl chloride was surface modified by a multistep physicochemical approach to improve bacterial adhesion prevention properties. This was fulfilled via surface activation by diffuse coplanar surface barrier discharge plasma followed by radical graft copolymerization of acrylic acid through surfaceinitiated pathway to render a structured high density brush. Three known antibacterial agents, bronopol, benzalkonium chloride, and chlorhexidine, were then individually coated onto functionalized surface to induce biological properties. Various modern surface probe techniques were employed to explore the effects of the modification steps. In vitro bacterial adhesion and biofilm formation assay was performed. Escherichia coli strain was found to be more susceptible to modifications rather than Staphylococcus aureus as up to 85% reduction in adherence degree of the former was observed upon treating with above antibacterial agents, while only chlorhexidine could retard the adhesion of the latter by 50%. Also, plasma treated and graft copolymerized samples were remarkably effective to diminish the adherence of E. coli.
