As a global leader in gold nanoparticle production, nanoComposix specializes in providing high-purity and monodisperse nanomaterials – delivering the quality you need for consistent results.

20 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 biosensors, immunodiagnostics, lateral flow assays, and more.

BioReady™ Gold Nanospheres have carboxyl covalently bound to the metal surface. Antibodies and other amine-containing biomolecules efficiently bind to carboxyl gold nanospheres using EDC-NHS chemistry to make highly stable conjugates. Review our conjugation protocol or contact our experts for support.

nanoComposix provides high quality nanomaterials that are precisely engineered and highly characterized. All products are supplied with batch-specific CoA’s including TEM, DLS, Zeta, and UV-Vis characterization data.
