13 nm spherical gold nanoparticles for passive adsorption are useful in applications such as spherical nucleic acid therapeutics and diagnostics

20 nm BioReady Gold Nanospheres for Covalent Conjugation 40 nm Endotoxin contamination can come from20 nm spherical gold nanoparticles for covalent conjugation are useful in applications such as biosensors, immunodiagnostics, and lateral flow assays. BioReady Gold Nanospheres have carboxyl covalently bound to the metal surface. Antibodies and other amine containing biomolecules efficiently bind to carboxyl gold nanospheres using EDC NHS chemistry to make highly stable conjugates.
