Description
As a global leader in gold nanoparticle production, AP USA specializes in providing high-purity and monodisperse nanomaterials – delivering the quality you need for consistent results.
80 nm spherical gold nanoparticles for covalent conjugation combine strong plasmonic optical properties with readily biofunctionalized surface chemistry. These nanoparticles are used in applications such as immunodiagnostics, lateral flow assays, biosensors, and more.
BioReady Gold Nanospheres have carboxyl covalently bound to the metal surface. Antibodies and other amine-containing biomolecules efficiently bind to carboxyl gold nanopheres using EDC-NHS chemistry to make highly stable conjugates. Review our conjugation protocol or contact our experts for support.
AP USA provides high quality nanomaterials that are precisely engineered and highly characterized. All our products are supplied with a batch-specific Certificate of Analysis including characterization data such as TEM, DLS, Zeta, and UV-Vis.
