Functionalized Gold Nanoparticles

Biomolecule functionalized gold nanoparticles offer a broad range of applications in biomedical and bioanalytical areas. In this work, we investigated the spectroscopy behavior of gold nanoparticles modified with mercapto amino acid, cysteine. We found that the interaction of gold nanoparticles with cysteine resulted in a shift in the plasmon bands to higher wavelengths at the lower concentration of cysteine and in acidity solution.

Insight Into

Antibody-functionalized gold nanoparticle constitutes a powerful interface biosystem for biomedical applications where the properties of gold nanoparticles and the specificity of antibody–antigen interactions are combined. This study provides insight into the key factors for the development of antibody functionalized gold nanoparticles focusing on the immobilization of the antibody. Here, we address an oriented antibody immobilization procedure on gold nanoparticles. It comprises chelatemodified gold nanoparticles that are designed for oriented immobilization of IgG antibodies (end on spatial orientation) through the metal-chelation to histidine-rich metal binding site in the heavy chain (Fc) of the antibody.
