报告摘要： Nanoparticles and nanomaterials are widely employed in electroanalytical sensors, particularly in amperometric devices, with significant improvements in performance often claimed, if not demonstrated. This lecture will present a critical overview seeking to identify where authentic changed behaviour exists between the macro- and micro-scale on the one hand and the nano-scale on the other. The following areas may be addressed. 1) Adsorption on nanoparticles and nanotubes; 2) The use of carbon nanotubes (CNTs) as electrode modifiers and the roles of (i) impurities in the CNTs arising from their manufacture via CVD, and (ii) the role of the CNTs in changing the mass transport regime to the electrode by virtue of altering a flat surface to a nanoporous one; 3) The role of nanomaterial porosity in general; 4)The investigation of electrode kinetics at nanoparticulate materials where the heterogeneity of the surface must be considered for correct mechanisms and kinetics to be inferred; 5) The modelling of transport to nano-sized electrodes where the diffusion and diffuse layers are of comparable size.
