Abstract

The use of tomato seeds as a source for alcohol dehydrogenase (ADH) for the determination of alcohols is described. The unique reactivity pattern of the tomato ADH is coupled with the speed and sensitivity of the mixed tissue/carbon paste configuration. The effect of experimental variables, such as pH, cofactor concentration, applied potential, or paste composition, is explored. In accordance to the substrate specificity, the lowest detection limits (in the micromolar level) are obtained for allyl alcohol and ethanol.

A mitochondria based amperometric biosensor was developed for the determination of L-glutamic acid. The biosensor was characterized using hexacyanoferrate(III) as the electrochemical mediator. The electrochemical behavior of the redox couple hexacyanoferrate(II)a(III) was improved by incorporating o

A number of tetrathiafulvalene (TTF) derivatives have been synthesized and tested as electron transfer niediators i n glucose oxidase-based amperornetric biosensors. Using cyclic voltanzmetry and stationary potential experiments, it is shown that several of these derivatives can effectively mediate
