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.
