摘要
A composite electrode was prepared by modifying glassy carbon micro particles with gold nanoparticles and glucose oxidase enzyme for glucose detection. In terms of analytical characteristics, a linearity was obtained in the concentration range between 50.0 and 1000.0 mu M with equation of y = 0.0015x + 0.2336 with the correlation coefficient of R-2 = 0.9801. R.S.D. value was calculated for 400 mu M glucose (n = 6) and found to be 4.89%. LOD and LOQ values were also calculated and revealed to be 52.9 mu M and 176.3 mu M, respectively. The developed system was also applied for detection of glucose in four types of alcoholic beverages.
