200 nm Magnetic Gold Nanoshells
Customers outside of the US & Canada: please visit your local distributor’s website to purchase this item using its SKU, or contact us here. Thank you!
200 nm magnetic gold nanoshells are useful in a variety of therapeutic and diagnostic applications such as biosensors, lateral flow assays, SERS, drug delivery, and photothermal therapy. These nanoparticles have a superparamagnetic core that enables easy manipulation such as separation or concentration, and the plasmonic optical properties of a gold nanoshell.
BioReady Magnetic Gold Nanoshells utilize a carboxyl ligand (lipoic acid) that is covalently bound to the metal surface enabling subsequent covalent conjugation. Antibodies and other amine-containing biomolecules efficiently bind to carboxyl gold nanoshells using EDC-NHS chemistry to make highly stable conjugates. Review our conjugation protocol or contact our experts for support.
