Abstract:
1. A method of analyzing a sample comprising the steps of: adding one or more metal nanoparticles to a liquid sample to form a nanoparticle solution within a sample chamber comprising at least 2 electrodes individually have a diameter of between about 1 μm and about 2 mm; adding an indicator species capable of undergoing a heterogeneous electrocatalytic redox reaction in the nanoparticle solution; detecting a discrete electrocatalytic property from the electrochemical amplification which correlates to an individual discrete nanoparticle collision; and wherein the discrete electrocatalytic property is a discrete step or spike selected from at least one of electrical current, potential, charge, resistance, capacitance, inductance, impedance, light, and color.
