Preparation of peptide functionalized gold nanoparticles using one pot EDC/sulfo-NHS coupling
Preparation of peptide functionalized gold nanoparticles using one pot EDC/sulfo-NHS coupling
Although carbodiimides and succinimides are broadly employed for the formation of amide bonds (i.e. in aminoacid coupling), their use in the coupling of peptides to water-soluble carboxylic terminated colloidal gold nanoparticles remains challenging. In this paper, we present an optimization study for the successful coupling of the KPQPRPLS peptideto spherical and rod-like colloidal gold nanoparticles. We show that the concentration, reaction time and the chemical environment are all critical to achieve the formation of robust, peptide-coated colloidal nanoparticles. Agarose gel electrophoresis was used for the characterization of conjugates.

Abstract
Although carbodiimides and succinimides are broadly employed for the formation of amide bonds (i.e. in aminoacid coupling), their use in the coupling of peptides to water-soluble carboxylic terminated colloidal gold nanoparticles remains challenging. In this paper, we present an optimization study for the successful coupling of the KPQPRPLS peptideto spherical and rod-like colloidal gold nanoparticles. We show that the concentration, reaction time and the chemical environment are all critical to achieve the formation of robust, peptide-coated colloidal nanoparticles. Agarose gel electrophoresis was used for the characterization of conjugates.
