dc.description.abstractThe aim of this work was to further evaluate the effect of colloidal solutions of gold nanoparticles (Au-NPs) on the performance of a carbon rod electrode modified with glucose oxidase. The amperometric response of the system at +0.3 V vs. Ag/AgCl was studied in the absence and in the presence of Au-NPs (6 nm and 13 nm in diameter) and in presence of N-methylphenazonium methyl sulfate (PMS) at pH 6.0. This study shows that the application of < 0.60 nmol 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 0.60 nmol L-1 of Au-NPs (13 nm) and 2 mmol L-1 of PMS linearly depends on the concentration of glucose in the range from 0.1 to 10 mmol L-1, the limit of detection is as low as 0.05 mmol L-1.en_US
