Application

Owing to their plasmonic properties nanoparticles of gold and silver find broad range of applications extending from diagnostics to molecular detection, photothermal and microwave-based therapies, and nanotoxicology. Colloidal silver nanoparticles also find applications in antimicrobial coatings, electronics and photovoltaics, and surface enhanced Raman spectroscopy (SERS) whereas the colloidal gold nanoparticles find applications in lateral flow assays (immunochromatographic assays) and as TEM labels and size standards.

Our silica shelled gold nanoparticles possess robust surface and exhibit high stability in variety of solvents. The silica shell offers a versatile surface for attaching functional groups or creating hydrophobic & hydrophilic surfaces. The presence of silica shell on the surface of gold nanoparticles also allows their easier deposition onto substrates and incorporation into different solvents, resins, and curable materials while protecting them from aggregation and preserving their optical properties.

Storage and Stability

DO NOT FREEZE. Store at 2-8C when not in use to maximize shelf life. Nanomaterials can be sensitive to high and low pH conditions and high salt concentrations. Use caution when changing environmental conditions as particles may aggregate.
