Our 40nm gold nanoparticle Biotin conjugate is manufactured using our InnovaCoat® technology. We have coated our high quality gold nanoparticles with a proprietary surface coat that covalently binds the Streptavidin molecule forming ultra stable conjugates. The resulting InnovaCoat® GOLD-Biotin nanoparticles can irreversibly bind Streptavidin or Avidin, meaning that there is no desorption of the antibody from the gold particle, which is a common problem associated with gold conjugates developed using passive adsorption techniques.
