Gold Nanoshells

Gold nanoshells provide an ultrabright label for lateral flow – up to 20× increases in lateral flow diagnostic sensitivity over 40 nm gold.

Carboxyl is covalently bound to the metal surface. The acid provides a highly negatively charged surface for subsequent conjugation to proteins, antibodies or peptides

BioReady products are specially formulated for the attachment of a molecular recognition element such as an antibody for lateral flow and biodiagnostics.

Provided at 20 OD in a .02 mM potassium carbonate solution.

Diameter
150 nm

Concentration
20 OD in aqueous .02 mM potassium carbonate

Gold nanoshells consist of a silica core surrounded by a gold shell. By changing the ratio of the size of the core to the thickness of the shell, the plasmon resonance can be tuned across the visible and infrared.

Polyvinylpyrrolidone (PVP) is a large polymer that offers excellent steric stability. Great choice for particles that may be exposed to a broad range of salt, pH, and solvent conditions.

NanoXact materials are high quality, unagglomerated and monodisperse nanoparticles.

Provided at .05 mg/mL or 1 mg/mL in water.

BioReady Gold Nanoshells – Streptavidin Ultrabright label for lateral flow – up to 20× increases in lateral flow diagnostic sensitivity over 40 nm gold.

Streptavidin tetramer is covalently bound to the particle surface via an amide bond. Streptavidin gold conjugates can be used for convenient conjugation of any biotinylated antibody, protein or oligonucleotide.

BioReady products are specially formulated for the attachment of a molecular recognition element such as an antibody for lateral flow and biodiagnostics.

Provided at 10 OD in an aqueous conjugation buffer composed of .1× PBS, .5% BSA, and .05% azide

Diameter
