  A simple colorimetric method has been developed for the detection of lead (Pb2+) in water samples using lipoic acidfunctionalized gold nanoparticles. The lipoic acid-functionalized gold nanoparticles are induced to aggregate in the presence of the Pb2+ which results in a change in the color of the functionalized gold nanoparticles. The change in color and the amount of Pb2+ producing the change could be monitored via UV-visible spectrophotometry. A good correlation coefficient of 0.9927 was obtained for the calibration curve of the colorimetric method. The method was applied in the determination of Pb2+ in water samples and the results compared to that of measurement carried out with Atomic Absorption Spectroscopy. .. View more»
