Abstract

Carbohydrate detectors employing abiotic fuel cell designs are disclosed. The detectors produce current output using reactions between chemical dyes in alkaline solutions and carbohydrates, such as glucose. A linear relationship between current output of the detector and glucose concentration has been observed. This relationship may be used with measurements of current output when the glucose concentration is unknown to determine the unknown glucose concentration. In certain embodiments, the abiotic detectors may further employ electrodes, such as high surface area carbon materials and commercial air breathing electrodes, without the use of catalysts (i.e., precious metals or biocatalytic species) for glucose detection Organic dyes, such as methyl viologen (MV), methylene blue, methylene green, Meldola's blue, indigo carmine, safranin O, and the like, may serve as the electron mediators.
