Description
Nanovex Biotechnologies provides Gold Nanoparticles capped with different ligands in order to help our customer to make progress in their specific applications. Nanoparticle surface modification is a key step to develop a reliable application.
Nanovex Biotechnologies offers Carboxyl PEGylated capped gold nanoparticles in sizes ranging from 15 to 100 nm.
Our Carboxyl PEGylated gold nanoparticles are supplied in water media in the absence of additional stabilizing agents or surfactants. Carboxyl PEGylated gold nanoparticles are more stable than conventional citrate capped gold nanopartiles against moderate concentration of salts in solution or handling.
The carboxylic group could be employed to perform a covalent linkage between the carboxylic group of gold nanoparticle and any molecule containing an amine group in their structure via EDC coupling through the formation of an amide group. Gold nanoparticle bioconjugates modified via covalent bond are more stable against desorption process than those obtained by simple passive adsorption.
Furthermore, the covalent conjugation of biomolecules to Nanovex Gold Nanoparticles is an alternative to avoid the loss of biofunctionality due to changes in the tertiary structure of the biomolecule.
Nanovex Carboxy PEGylated Gold Nanoparticles could be employed as a building block structure to perform the immobilization of molecules or biomolecules containing primary amine groups in their structure. Some applications are protein conjugation, western blot/dot blot, microscopy applications, lateral flow assays or ELISA.
Our functionalized Nanovex Gold Nanoparticles are available in different sizes ranging from 15 to 100 nm.
Our carboxyl PEGylated gold nanoparticles are supplied in water media in the absence of additional stabilizing agents or surfactants. Carboxyl PEGylated gold nanoparticles are more stable than conventional citrate capped gold nanopartiles against moderate concentration of salts in solution or handling.
