After an extensive period of product research and stability tests we are proud to announce the introduction of a series of Carboxyl-functionalized Gold Nanoparticles. This product has been developed to facilitate conjugating gold nanoparticles to molecules that cannot be conjugated via the classic direct adsorption method. The product is especially suited for covalent conjugation of small ligands. Detailed information can be found here and in the Newsletter dedicated to this topic.
