150 nm Gold Nanoshells for Conjugation
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!
150 nm gold nanoshells for conjugation are useful in applications such as immunodiagnostics, lateral flow assays, nanomedicine, drug delivery, and biosensors. BioReady™ Gold Nanoshells enable enhanced sensitivity in lateral flow assays (LFA) due to their intense optical signal. Integration of these nanoparticles into LFAs can provide increased signal-to-noise ratios and lowered limits of detection for your target of interest.
BioReady Gold Nanoshells are available with the following surfaces:
- Carboxyl - for covalent conjugation
- Citrate - for passive adsorption
-
Streptavidin - for high-affinity binding to biotin-labeled molecules
