The amperometric response of the system at +0.3V vs. Ag/AgCl was studied in the absence and in the presence of Au-NPs (6nm and 13nm in diameter) and in presence of N-methylphenazonium methyl sulfate (PMS) at pH6.0. This study shows that the application of <0.60nmol L−1 concentrations of Au-NPs increases the rate of mediated electron transfer, and this effect does not depend on the diameter of Au-NPs. The analytical signal in the presence 0.60nmol L−1 of Au-NPs (13nm) and 2mmol L−1 of PMS linearly depends on the concentration of glucose in the range from 0.1 to 10mmol L−1, the limit of detection is as low as 0.05mmol L−1.
