Gold Nanoparticles and Their Applications

Gold nanoparticles (AuNPs) represent versatile materials extensively employed in biomedical sciences and applications involving electrochemical sensors. These tunable nano-materials exhibit exceptional thermo-mechanical properties, a high surface area, and low toxicity, contributing to their widespread utility in various fields.

Application

Citrate-stabilized gold nanoparticles (AuNPs) offer diverse applications, including:

Neutrophil labeling for monitoring the impact of various drugs

Immobilization of proteins in biosensor applications

Serving as a nano-carrier in drug delivery systems for the controlled release of hydrophobic drugs

This product is well-suited for the adsorption of thiolated ligands, such as oligonucleotides and polyethylene glycols. The increased stability of these gold nanoparticles makes them particularly suitable for use in physical and optical applications.

It is important to note that this product is not recommended for protein adsorption. For gold nanoparticles specifically designed for the adsorption of proteins and other ligands for conjugate development, please refer to Merck's gold nanoparticles stabilized in PBS.

Characterized by high monodispersity (<12% variability in size and shape), this material exhibits significantly improved surface reactivity. Applications include Surface Enhanced Raman Labels, Sensing/Detection, Biological Targeting, Plasmonics, and Electronics.
