Bacterial adhesion to surface hydrophilic and hydrophobic contact lenses.
The aim of this paper was to determine the adhesion of two physico-chemically characterized bacterial strains to a surface hydrophilic (CL A, water contact angle 57 degrees) and hydrophobic (CL B, water contact angle 106 degrees) hydrogel contact lens (CL) with and without an adsorbed tear film in a parallel plate flow chamber. Hydrophobicity (by water contact angles), charge (by particulate mi...
متن کاملFrom hydration repulsion to dry adhesion between asymmetric hydrophilic and hydrophobic surfaces.
Using all-atom molecular dynamics (MD) simulations at constant water chemical potential in combination with basic theoretical arguments, we study hydration-induced interactions between two overall charge-neutral yet polar planar surfaces with different wetting properties. Whether the water film between the two surfaces becomes unstable below a threshold separation and cavitation gives rise to l...
متن کاملEarly osseointegration to hydrophilic and hydrophobic implant surfaces in humans.
OBJECTIVE To evaluate the rate and degree of osseointegration at chemically modified moderately rough, hydrophilic (SLActive) and moderately rough, hydrophobic (SLA) implant surfaces during early phases of healing in a human model. MATERIAL AND METHODS The devices used for this study of early healing were 4 mm long and 2.8 mm in diameter and had either an SLActive chemically modified or a mod...
متن کاملFibronectin Adsorption on Hydrophilic and Hydrophobic Surfaces
Studies have been carried out on the adsorption properties of plasma fibronectin (FN) on hydrophobic and hydrophilic surfaces. The hydrophobic and hydrophilic surfaces used were nonwettable bacteriological dishes and wettable tissue culture dishes, respectively. At low plasma FN concentrations, there was more plasma FN binding to hydrophobic surfaces than to hydrophilic surfaces. Under these co...
متن کاملColloidal adhesion to hydrophilic membrane surfaces
Colloidal adhesion to membrane surfaces is an important parameter in determining membrane fouling propensity and in optimizing membrane cleaning strategies. It has previously been demonstrated that acid–base interactions can significantly affect colloid–membrane interaction as a colloid approaches a membrane surface, however, the effect of acid–base interactions on adhesion has received less at...
