Description générale

Gold nanoparticles (AuNPs) are colloidal nanoparticles with multiple surface functionalities that can be used in the development of new biomaterials. AuNP has a spherical structure with a large surface to volume ratio and excellent biocompatibility. It is majorly used in a variety of biomedical applications ranging from diagnostics to drug delivery.

Application

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.
