Silver nanoparticles are being used in numerous technologies and incorporated into a wide array of consumer products that take advantage of their desirable optical, conductive, and antibacterial properties. Diagnostic Applications: Silver nanoparticles are used in biosensors and numerous assays where the silver nanoparticle materials can be used as biological tags for quantitative detection. Conductive Applications: Silver nanoparticles could be utilized in conductive inks and integrated into composites to enhance thermal and electrical conductivity. Antibacterial Applications: Silver nanoparticles are used in apparel, footwear, paints, wound dressings, appliances, cosmetics, and plastics for their antibacterial properties. Optical Applications: Silver nanoparticles could be utilized in efficiently harvest light and enhanced optical spectroscopies including metal-enhanced fluorescence (MEF) and surface-enhanced Raman scattering (SERS). Silver nanoparticles in form of colloid could be more efficiently used in these applications due to homogeneous distributions of particles. Colloidal silver products also remain available in many countries as dietary supplements and homeopathic remedies.
Medical textile Diagnostics Optical Applications


The real average size of spherical particle in this product is about 10 nm, while hydrodynamic particle size resulted by DLS analysis is 90 nm with pdi equal to 0.384. NaNO3 has been resulted as byproduct from the synthesis procedure. This colloid is electro-sterically stable and silver concentration is 5500 ppm in it. Silver particles are stabilized easily in nano-dimension which leads to formation more stable colloids. The most noticeable advantages of silver nanoparticles are in biomedicine. It could be mentioned that in nano-dimension, antibacterial effect of silver increases significantly, so that they are able to destroy over 650 bacterial species. These nanoparticles have significant antifungal activities against some ringworms. Silver nanoparticles disrupt fungal structure and cause significant damage to fungal cells. It is also demonstrated the cytoprotective activity of silver nanoparticles (5-20 nm) toward HIV-1 infected cells. The modified electrochemical properties of silver nanoparticles can also offer faster response times and lower detection limits in nano-scale sensors.

Manufacturer's Description

Colloidal silver is a mineral solution containing silver ions and very small charged silver particles suspended in a liquid medium. As the particles have the same electrostatic charge، they repel each other and this keeps them in uniform suspension throughout the medium. This is why it is called a colloid. Although silver ions are important, a 100% solution of silver ions is not colloidal silver. Various names have been used to describe colloidal silver, such as silver sols. It is sometimes referred to as «Nano Silver» as the particles are in the range of 1 to 100 nm.
