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.

This material is highly monodisperse (<12% variability in size and shape); and provides significantly improved surface reactivity. Applications include Surface Enhanced Raman Labels[1], Sensing/Detection[2], Biological Targeting[3], Plasmonics[4] and Electronics[5].
The removal of reactants means that further growth of the nanoparticles is also inhibited leading to a longer lasting material.
