A novel optical biosensor assembled with gold colloidal nanoparticles on gold plate surface has been constructed via 1,4dithiothreitol and L-cysteic acid for detection of bio-molecules like antigen, antibody protein and DNA plasmid, which exhibited distinct optical properties of localized surface plasmon resonance (LSPR). The prepared nano gold sol were characterized by using UV-Vis absorption spectroscopy, transmission electron microscopy (TEM), and cyclic voltammetry (CV), indicating that the… CONTINUE READING
