摘要：A method for electrochemical impedance spectroscopy uses interdigitatedelectrodes functionalized with a first species and nanoparticles functionalized with asecond species that preferentially attaches to the first species. The nanoparticles are
composed of a material with a dielectric constant (k value) greater than 2. The chemicallyfunctionalized electrodes are then exposed to a solution containing the chemicallyfunctionalized nanoparticles which then become immobilized on the electrodes throughthe attachment of the first species to the second species. The impedance spectrum ismeasured and an amount of the first species is then determined from the measuredspectrum. Because the high-k dielectric nanoparticles increase the double-layercapacitive impedance, the sensitivity of determining the amount of the first speciesattached to the second species is enhanced.
