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.
