Increasing patient safety through the use of silver-coated 100% silicone Foley catheter system

Anti-bacterial performances and biocompatibility of bacterial cellulose/graphene oxide composites

“…The electrostatic double-layer interaction DE EL between bacterium 1 and a at solid surface 2 can be described as: 53,54…”

“…According to the extended DLVO theory, if the total interaction energy DE TOT is negative, adhesion is favorable. [53][54][55] If DE TOT is positive, adhesion is unfavorable. Bacterial adhesion should decrease with DE TOT increasing.…”

“…Zeta potentials and diameters of tested bacteriaThis journal is © The Royal Society of Chemistry 2015 zeta potential of solid materials, which was taken as À25 mV in this calculation. 3 and 3 0 are relative dielectric permittivity of water (78.55 for water at 25 C) and the permittivity under vacuum (8.854 Â 10 À12 C V À1 m À1 ) respectively, k is Debye-Hǔckel length and also an estimation of the effective thickness of the electrical double layer (1/k ¼ 1.1 nm) 53,54. …”

Influence of reducers on nanostructure and surface energy of silver coatings and bacterial adhesion

“…The silver-coated medical devices, such as dressings, heart valves, central venous catheters and urinary catheters, have been proved to reduce the infections effectively. The silver-coated silicone Foley catheters are effective at reducing the incidence of catheter-associated urinary tract infections and resistant organisms in an acute care hospital [8]. It has been reported that the surface energy of coatings also has significant influence on initial bacterial adhesion [9][10][11].…”
