Metal Dispersion

Silver Colloidal Applications include molecular diagnostics and photonic devices, which take advantage of the novel optical properties of these nanomaterials. An increasingly common application is the use of silver nanoparticles for antimicrobial coatings, and many textiles, keyboards, wound dressings, and biomedical devices now contain silver nanoparticles that continuously release a low level of silver ions to provide protection against bacteria.

Silver Colloidal is invaluable to solder and brazing alloys, batteries, dentistry, glass coatings, LED chips, medicine, nuclear reactors, photography, photovoltaic (or solar) energy, RFID chips (for tracking parcels or shipments worldwide), semiconductors, touch screens, water purification, wood preservatives and many other industrial uses. Washington-based industry group the Silver Institute calls it “the indispensable metal.

Silver Colloidal sensitivity to light has found fast-growing use in the photovoltaic, or solar energy, industry. Using silver as a conductive ink, photovoltaic cells transform sunlight into electricity. Silver nanoparticles are an effective antibacterial substance and are found as additive in various medical applications.

Silver Colloidal, Cylindrical colloidal-silver-impregnated ceramic filters for household (point-of-use) water treatment were manufactured and tested for performance in the laboratory with respect to flow rate and bacteria transport. Colloidal silver was appliedto filters in different quantities and ways dipping and painting. Filters were also tested without any colloidal-silver application. colloidal silver by either painting with, or dipping in, a colloidal-silver solution. The colloidal silver is hypothesized to act as a microbial disinfectant.

Silver Colloidal, The solute- and bacteria-transport experimentsprovide improved understanding of the relative affects of filtration and colloidal-silver disinfection on bacteria removal by the ceramic filters. Bacteria transport data for the three filters prior to application of colloidal silver support the hypothesis that steric rejection or size exclusion chromatography is a significant mechanism of bacteria removal in the ceramic filters. Filters with smaller pores caused higher rejection of bacteria.
