| Abstract: | Alcohol dehydrogenase(ADH) and the oxidized form of nicotinamide adenine dinucleotide(NAD+) were cross-linked directly in aid of the reaction of thionine and toluene diisocyanate(TDI) on the surface of glassy carbon electrode to yield a reagentless alcohol sensor. The NAD+ was converted to NADH by oxidation of alcohol catalyzed by ADH and the NADH formed was oxidized electrochemically to the original NAD+ by thionine-TDI mediator, thus giving the catalytic current for target analysis. The peak current was linearly related to the concentration of alcohol in the range of 1-15 mmol/L. The influence of various experimental conditions was also explored for optimum analytical performance.The sensor remains relatively stable for about 15 days. |
