  • Precisely engineered surface with an optimized carboxyl group density for easy conjugation.

Applications

  • Ideal for development of silver conjugates for use in for example:
  • Immunoblotting
  • Lateral Flow Assays
  • LSPR Assays
  • Microscopy Applications (e.g. TEM, Darkfield)

Properties

The carboxyl functionalized silver nanoparticle surface allows for covalent conjugation of antibodies, proteins and other ligands using standard EDC/NHS coupling chemistry.

The precisely engineered silver nanoparticle surface with extended carboxyl groups maximizes conjugation efficiency by minimizing steric hindrance while still maintaining low non-specific protein binding. These features results in reliable and reproducible conjugates.
