“…An alternative method to enhance the properties of silver-based materials is the incorporation of silver ions or nanoparticles into hydrogels. Many groups have successfully developed such hydrogels that allow a slow and controlled release of silver ions, 309 as, for instance, a PET surface modified by silver ion implantation, 332 silver nitrate-catalyzed polyacrylamide gels, 333 and PET-based hollow fibers containing silver particles. 334 Slow and controlled silver release could also be achieved from polymers.…”

“…Biofilm infections are thus difficult to treat with conventional antibiotics, almost all of which have been developed to combat bacteria in their planktonic state. Therefore, this public health problem requires multifaceted approaches ranging from developing biomaterials that can prevent bacterial adhesion (Furno et al 2004;Zhao and Liu 2006;Li et al 2007) to exploring entirely new therapeutic concepts (Reddy and Ross 2001;Harris and Richards 2006;Donelli et al 2007).…”

Microfluidic devices were used to study the influences of hydrodynamics of local microenvironments on Staphylococcus epidermidis (S. epidermidis) biofilm formation and the effects of a poly(beta-1,6-N-acetyl glucosamine)-hydrolyzing enzyme (dispersin B) and/or an antibiotic (rifampicin) on the detachment of the biofilm. Elongated, monolayered biofilm morphologies were observed at high flow velocity and fluid shear locations whereas large clump-like, multilayered biofilm structures were produced at low flow velocity and fluid shear locations. Upon dispersin B treatment, most of the biofilm was detached from the microchannel surface. However, a trace amount of bacterial cells could not be removed from corner locations most likely due to the insufficient wall shear stress of the fluid at these locations. Dispersin B or rifampicin treatment was effective in delaying the dispersal behavior of bacterial cells, but could not completely remove the biofilm. Combined dynamic delivery of dispersin B and rifampicin was found to be effective for complete removal of the S. epidermidis biofilm.

“…An increased number of functional groups on the PET surface could enhance binding and reduce binder consumption in coating with PVC, a bulk application for the production of for example, truck tarpaulins [27] . Increased hydrophilicity of PET (i.e., a 15 ° lower contact angle) has been demonstrated to reduce bacterial adhesion and consequently infections of cardiovascular implants, such as artifi cial heart valve sewing rings and artifi cial blood vessels [28] . Similarly, in the production of fl exible electronic device s ( FED s) such as displays or photovoltaic cells, surface hydrophilization is required for the attachment of functional layers [29] .…”
