Silver Nanoparticle Applications
Silver nanoparticles are one of the most commonly utilized nanomaterials due to their anti-microbial properties, high electrical conductivity, and optical properties.
Silver nanopaticles are widely incorporated into wound dressings, and are used as an antiseptic and disinfectant in medical applications and in consumer goods. Silver nanoparticles have a high surface area per unit mass and release a continuous level of silver ions into their environment. The silver ions are bioactive and have broad spectrum antimicrobial properties against a wide range of bacteria. By controlling the size, shape, surface and agglomeration state of the nanoparticles, specific silver ion release profiles can be developed for a given application.
Incorporation of silver particles into plastics, composites, and adhesives increases the electrical conductivity of the material. Silver pastes and epoxies are widely utilized in the electronics industries. Silver nanoparticle based inks are used to print flexible electronics and have the advantage that the melting point of the small silver nanoparticles in the ink is reduced by hundreds of degrees compared to bulk silver. When scintered, these silver nanoparticle based inks have excellent conductivity.
Silver nanoparticles have unique optical properties because they support surface plasmons. At specific wavelengths of light the surface plasmons are driven into resonance and strongly absorb or scatter incident light. This effect is so strong that it allows for individual nanoparticles as small as 20 nm in diameter to be imaged using a conventional dark field microscope. This strong coupling of metal nanostructures with light is the basis for the new field of plasmonics. Applications of plasmonic silver nanoparticles include biomedical labels, sensors, and detectors. It is also the basis for analysis techniques such as Surface Enhanced Raman Spectroscopy (SERS) and Surface Enhanced Fluorescent Spectroscopy.
There is increasing interest in utilizing the large scattering and absorption cross sections of plasmonic silver nanoparticles for solar applications. Since the nanoparticles act as efficient optical antennas, very high efficiencies can be obtained when the nanoparticles are incorporated into collectors.

Spherical Silver Nanoparticles
Size: In addition to the wide range of standard sizes of silver nanospheres that we have in stock, we have fabricated additional sizes of uniform, unagglomerated particles on demand for customers. NanoComposix has successfully manufactured sizes spherical silver nanoparticles for customers ranging from 300 nm up to 2 μm, as shown below.
Surface Chemistry & Coatings: Our standard silver nanoparticles have a variety of different anionic and cationic capping ligands available, ranging from displaceable small molecules to polymer coatings. In addition, we can fabricate nanomaterials with specific functional groups, polymers, biomolecules, and inorganic coatings. Examples of custom aqueous solvent compatible surfaces that we have fabricated include polyvinyl alcohol (PVA), polyethylene glycol (PEG) of different molecular weights and different terminal functional groups, or biomolecules such as streptavidin. We have coated particles with inorganic coatings like titania (TiO2) and applied our uniform and precisely controlled silica coatings to a wide range of sizes beyond our standard products. We have also successfully fabricated hydrophobic organic solvent compatible surfaces such as alkylsilane-, phenyl- and cyclic azasilane-functionalized silica groups.
