“…It has been observed that bacterial cells have a greater tendency to attach to hydrophobic surfaces than hydrophilic surfaces. However, in some cases the surface tension of the suspending medium and the bacteria can change this expectation [62,64]. So, the relationship between the number of adhering microorganisms in relation to the surface hydrophobicity still seems to be controversial [65,66].…”

“…Gram-negative bacterium is composed of an outer membrane with lipids and lipopolysaccharides with high ratio of nitrogen/carbon due to the presence of proteins, which cause the surface to be more hydrophobic [64]. Figure 2A qualitatively demonstrates the different response of these bacterial strains exposed to a set of different polymer surfaces.…”

A novel rapid method for bacterial differentiation is explored based on the specific adhesion pattern of bacterial strains to tunable polymer surfaces. Different types of counter ions were used to electrochemically fabricate dissimilar polypyrrole (PPy) films with diverse physicochemical properties such as hydrophobicity, thickness and roughness. These were then modulated into three different oxidation states in each case. The dissimilar sets of conducting polymers were Principal Component Analysis showed that each strain of bacteria had its own specific adhesion pattern. Hence, they could be discriminated by this simple, label-free method. , based on tunable polymer arrays combined with pattern recognition.

“…Targeting bacterial adhesion to solid surfaces is a promising approach to prevent biofilm-related disease [1][2][3]. This particularly holds true for the oral cavity where the long-standing presence of biofilms on teeth is the main cause of dental caries and periodontitis [4,5].…”

The bovine milk protein osteopontin (OPN) may be an efficient means to prevent bacterial adhesion to dental tissues and control biofilm formation. This study sought to determine to what extent OPN impacts adhesion forces and surface attachment of different bacterial strains involved in dental caries or medical device-related infections. It further investigated if OPN's effect on adhesion is caused by blocking the accessibility of glycoconjugates on bacterial surfaces. Bacterial adhesion was determined in a shear-controlled flow cell system in the presence of different concentrations of OPN, and interaction forces of single bacteria were quantified using single-cell force spectroscopy before and after OPN exposure. Moreover, the study investigated OPN's effect on the accessibility of cell surface glycoconjugates through fluorescence lectin-binding analysis. OPN strongly affected bacterial adhesion in a dose-dependent manner for all investigated species (Actinomyces naeslundii, Actinomyces viscosus, Lactobacillus paracasei subsp. paracasei, Staphylococcus epidermidis, Streptococcus mitis, and Streptococcus oralis). Likewise, adhesion forces decreased after OPN treatment. No effect of OPN on the lectin-accessibility to glycoconjugates was found. OPN reduces the adhesion and adhesion force/energy of a variety of bacteria and has a potential therapeutic use for biofilm control. OPN acts upon bacterial adhesion without blocking cell surface glycoconjugates. ARTICLE HISTORY

“…Therefore, the latest approaches concern the designing of new devices with surfaces that are capable of limiting bacterial adhesion and/or viability (for a review see Desrousseaux et al, 2013). The majority of the new nanotechnological approaches to combat biofilm formation are based on the use of NPs to functionalize the surface of biomaterials by coating (Roe et al, 2008;Applerot et al, 2012), impregnation (Shi et al, 2006), or by embedding nanomaterials (Beyth et al, 2008).…”
