Real-time measurement of molecular adsorption on the gold-coated AAO. (a) Interference spectrum for the gold-coated AAO before and after exposure to 0.5 mM MUA with a single fringe signal representing a wavelength shift of interference maxima (on the right). (b) Changes of the EOT signal by continuous addition of different concentrations (0.01 to 1 mM) of MUA. The scheme of assembly of thiol molecules on gold surface is presented.
