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.
Peak resonance (SPR) gold nanorods combine strong plasmonic optical properties with unique anisotropic morphology. These nanoparticles are compatible with conventional 650 nm lasers and are useful in a broad range of applications from immunodiagnostics, biosensors, sensing, photothermal therapy, SERS, optical filters, and more.
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.
