NanoXact Gold Nanoshells – PEG·

Gold nanoshells consist of a silica core surrounded by a gold shell. By changing the ratio of the size of the core to the thickness of the shell, the plasmon resonance can be tuned across the visible and infrared. Learn more ❯

Polyethylene glycol (PEG) is a 5 kDa ligand that is covalently bound to the particle’s surface. The PEG surface provides the highest stability in aqueous buffers and protic solvents. Learn more ❯

NanoXact materials are high quality, unagglomerated and monodisperse nanoparticles. Learn more ❯
