PVP (Polyvinylpyrrolidone) Learn more +
  • Associates very strongly to metal surfaces, giving excellent colloidal stability over a wide range of conditions
  • Nanoparticles can be dispersed in a wide variety of protic and aprotic polar solvents
  • Stable in high ionic strength solutions and at high concentrations
Lipoic Acid Learn more +
  • Dithiol forms a strong, stable bond with metal surfaces and the acid provides a highly negatively charged surface
  • The free carboxylic acid can be used for conjugation or labeling; contact us to discuss your application
PEG (Polyethylene Glycol) Learn more +
  • Provides excellent dispersibility in water and protic solvents and increases compatibility in biological systems
  • Covalently bound to the nanoparticle surface to prevent desorption over time and increase colloidal stability
  • Custom variants available with PEG of different molecular weights and free functional groups for labeling or conjugation
