Overview
Surface Citrate BPEI Carboxyl PEG Polystyrene PVP PVP (dried) Silica Shelled Silica Shelled, Aminated
Description Easiest standard surface to displace with other molecules. Covalently bound. Conjugatable surface. Covalently bound. Conjugatable surface. Highest stability in aqueous buffers and polar organic solvents. Hydrophobic surface that allows for dispersion in a wide range of polar organic solvents. Large polymer surface. Stable in a wide variety of solvents. Powder format allows greater flexibility with solvent choice and concentration. Greatest solvent compatibility. Preserves plasmonic properties upon deposition. Conjugatable surface. Greatest solvent compatibility. Preserves plasmonic properties upon deposition.
