“…In a recent paper, the antimicrobial activities /of AgN03, AgCl and Ag ions obtained through electrochemipal methods were compared. We demonstrated that anodic silver ions showed highest activity also when challenged with large inocula (Simonetti et al 1992). This rnicrobicidal activity appeared particularly enhanced at higher temperatures.…”

“…Electrochemical silver solutions were prepared using a 4.5-V battery connected to two cylindrical silver electrodes (length, 8 cm; cross section, 4 mm'; distance between electrodes, 3cm) in a 100-mL glass cylinder. In all samples, the Ag+ concentration was determined, as previously reported (Simonetti et al 1992), by a potentiometric method using an Ag,S electrode. Silver ion concentration was adjusted to M in each experiment.…”

The microbicidal effectiveness against Gram-positive and Gram-negative bacteria and Candida albicans of electrochemical silver ions in aqueous solutions containing nonionic surfactants was investigated. From the perspective of the possible use of anodic silver as a preservative in cosmetic or pharmaceutical preparations, microbicidal efficacy was also studied in oil/water model dispersions. Surfactants and botanical extracts partially inhibited the microbicidal effectiveness of anodic silver. Nevertheless in all the experimental conditions, silver ions reduced the microbial concentration up to 4 log units of the starting inoculum in less than 6 h. The wide microbicidal spectrum and the high rate of kill of silver ions appear, therefore, attractive enough to suggest a possible utilization of anodic silver as a preserving agent.

“…12 Ag nitrated coatings have also been studied for years because Ag ion is known to exhibit antibacterial properties. 13 Stainless steel pins coated with Ag have been found to decrease the adhesion and colonization of S. aureus, Staphylococcus epidermidis, and P. aeruginosa around the coated implant. 14,15 However, there are also reports that Ag is toxic to host cells, causing severe toxic reactions.…”

Protein-resistant coatings have been studied for inhibiting biofilm formation on implant devices. In this study, titanium (Ti) surfaces were biofunctionalized with poly(ethylene glycol) (PEG) by electrodeposition and were evaluated as biofilm substrates under an oral simulated environment. Streptococcus gordonii, an early colonizer of oral biofilms, was inoculated on Ti and PEG-electrodeposited Ti (PEG-Ti) surfaces and was analyzed quantitatively and topographically. Streptococcus mutans supplemented with sucrose, a late colonizer mainly found in dental plaque, was also used to form biofilms on the surfaces of Ti and PEG-Ti for 20 h followed by sonication as a means of detaching the biofilms. The results indicated that the attachment of S. gordonii on PEG-Ti surfaces was inhibited compared with Ti, and the S. mutans biofilm was easier to be detached from the surface of PEG-Ti than that of Ti. Moreover, the presence of PEG electrodeposited on Ti surface inhibited salivary protein adsorption. The degree of detachment of biofilms from PEG-Ti was associated with the inhibition of the salivary protein adsorption, suggesting weak basal attachment of the biofilms to the electrodeposited surfaces. Therefore, controlling protein adsorption at the initial stage of biofilm formation may be an effective strategy to protect metal surfaces from bacterial contamination not only in dental manipulations but also in orthopedic applications.

“…8 -10 Colloidal silver is a completely nontoxic, tasteless, internally and externally applicable, broad-spectrum germ fighter and disinfectant, which can significantly reduce the length and severity of many bacterial infections. [11][12][13] Silver is used as coating 14,15 and also as particulate filler 16,17 in various polymers to generate antimicrobial property. Many commercial fillers (containing silver) available in the markets rely on certain carrier materials, such as titanium dioxide, sodium hydrogen zirconium phosphate, or some zeolite, as carriers of silver whose presence will improve the water permeability of the composite specimen.…”

The efficiency of various silver-based antimicrobial fillers (elementary silver and silver substituted materials) in polyamide (PA) toward their silver ion (Ag+) release characteristics in an aqueous medium was investigated and discussed. Anode stripping voltammetry (ASV) was used for the quantitative estimation of Ag+ release from these composites. The biocidal (Ag+) release from the composites was found to be dependent on the time of soaking in water and the nature of the filler. The long-term Ag+ release capability of the elementary silver-based PA/Ag composite is promising compared with the commercial counterparts. The silver ion release potential of polyamide composites where the silver filling was performed by using supercritical carbon dioxide (scCO2) is also discussed. The composites release Ag+ at a concentration level capable of rendering antimicrobial efficacy and proved to be active against the microbes. A good agreement exists between the Ag+ release experiments and antimicrobial test results. The observed results on the influence of the nature of the filler and crystallinity on the biocidal release and the varying long-term release properties could be helpful in the design of industrially relevant biomaterials.
