Abstract: | Glassy carbon electrode modified with boron oxide nanoparticles supported on multiwall carbon nanotubes was obtained via a facile approach. The as-prepared modified electrode exhibits excellent electrocatalytic activity toward the redox of glucose in pH 7.0 phosphate buffer solution. The electrochemical response of the modified electrode to glucose shows a linear range of 1.5-260 μM with a correlation coefficient of 0.9986 and the calculated detection limit is 0.8 μM at a signal-to-noise ratio of 3, which makes it useful for developing the electrochemical determination of glucose concentrations without using glucose oxidase at physiological pH. |
