Product Description

Description:

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.The BioReady gold nanospheres are well suited for passive conjugation of antibodies, proteins, peptides, and other biomolecules.

The BioReady citrate gold nanoparticles have a “naked” particle surface which contains a weakly bound citrate molecule as stabilizer. The citrate is readily displaced in presence of proteins and allows passive adsorption (also referred to as physisorption). The mechanism of adsorption is based on Van der Waals interactions between the proteins (e.g. antibodies) and the surface of the particles. The resulting forces between the antibody and the nanoparticle are influenced by the coupling environment. Our BioReady citrate gold is provided at an optical density (OD) of 20 at pH ~8.0–8.5. A pH titration should be performed to optimize the pH of conjugation.
