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 silver nanospheres 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 silver nanospheres 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 and away from light 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.

Advances of Noble Bimetallic Nanoparticles in Detection of Glucose Level

Dr. David Medina Cruz et. al. investigate advances in noble bimetallic nanoparticles (BMNP) to more precisely measure and monitor glucose levels in the blood. They focus on the use of enzyme-free silver and gold nanoparticles, such as Ag-Au, Ag-Pt, Ag-Pd, and Au-Pt, and how their structures contribute to biosensor detection.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
