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 ‘Ultra Uniform Gold Nanospheres′ are ideal for applications requiring the highest uniformity in size and shape. These particles have nearly perfect spherical shape, smooth surfaces, and extremely narrow size distributions (CV < 5-6%). These gold nanospheres are available in sizes varying from 10 nm to 100 nm at a concentration of 0.05 mg/mL (gold content) in a 2 mM sodium citrate solution and their surface is stabilized with a carboxyl-terminated ligand.

Due to their high uniformity in size and shape, these Au nanospheres scatter a single color of light under dark field microscope imaging. The high purity of their light scattering signatures makes them perfect scattering labels for imaging and building blocks for plasmonic nanostructures and devices.

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.
