Wide selection of surfaces & material types
Each surface imparts unique functional benefits, allowing you to select the surface that works best for your needs. For example, a bare citrate surface is easily displaced by other molecules, PVP offers stability in many polar solvents, and PEG offers good stability in high salt concentrations and biological buffers. For gold and silver nanoparticles, choose from surface options such as Bare (Citrate), PVP or PEG polymers, Tannic Acid, Carboxyl (Lipoic Acid), and Cationic/Amine (BPEI). Platinum is available with a Bare (Citrate) surface and magnetite is offered stabilized with PVP.
