30 nm Gold Nanospheres
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!
30 nm spherical gold nanoparticles are useful in applications such as biosensors, plasmonic optical effects, and drug delivery systems. For cell culture and other sensitive biological applications, a low-endotoxin formulation filtered through a 0.22 µm membrane is available at 1 mg/mL.
nanoComposix provides high quality, monodisperse, and aggregation-free nanomaterials. All our products are supplied with a batch-specific Certificate of Analysis including characterization data such as TEM, DLS, Zeta, and UV-Vis.
Intended for Research Use Only. Not for use in diagnostic procedures. Contact us for custom formulations and ISO 13485/cGMP compliant materials, or bulk supply requirements.
