Description

General description

Gold nanoparticles (AuNPs) are versatile materials widely used in biomedical sciences and electrochemical sensor based applications. AuNPs are tunable nano-materials with excellent thermo-mechanical properties, high surface area, and low toxicity.

Application

Citrate stabilized AuNPs can be used for a variety of applications such as:

• neutrophil labeling for monitoring the effect of different drugs
• immobilization of proteins for biosensor applications
• nano-carrier for drug delivery system for the release of hydrophobic drugs.

Ideal for adsorption of thiolated ligands such as oligonucleotides and polyethylene glycols. Also, due to the increased stability, these gold nanoparticles are ideal for use in physical and optical applications. Note: This product is not ideal for protein adsorption. For gold nanoparticles suitable for adsorption of proteins and other ligands for conjugate development, please see our gold nanoparticles stabilized in PBS.

This material is highly monodisperse (<12% variability in size and shape), and provides significantly improved surface reactivity. Applications include Surface Enhanced Raman Lables, Sensing/Detection, Biological Targeting, Plasmonics and Electronics.
