Which Surface Should I Choose?

  • Maximizes sensitivity
  • More cost effective at large production scales
  • Requires additional EDC/Sulfo-NHS activation step

BioReady carboxyl (–COOH) gold is an effective and economical nanoparticle for covalent conjugations to proteins through carbodiimide crosslinker chemistry. Covalent coupling of proteins (e.g. antibodies) to a gold nanoparticle surface yields robust and stable gold particle conjugates. The nanoparticles are surface functionalized with a tightly bound monolayer that contains terminal carboxylic acid functional groups which can be activated through EDC/Sulfo-NHS chemistry to generate gold nanoparticle-antibody amide bonds. The EDC/Sulfo-NHS chemistry requires an extra step to activate the carboxyl group but can be performed at scale at reasonable cost, making carboxyl gold the most cost-effective method of covalently binding antibodies to gold.
