“…Tani et al utilized carbon nanotube gel, which was composed of a mixture of single-walled carbon nanotube (CNT), an ionic liquid, and a thermostable Dproline dehydrogenase (D-ProDH) immobilized on the electrode for the determination of D-amino acids in wine and vinegar samples. When a critical comparison with CNT, Ketjen Black, and carbon powder was also carried out, the CNT/D-ProDH immobilized electrode showed the highest sensitivity and the lowest detection limit for Dproline (Tani et al 2009). …”

The importance of analyses of different parameters in food products and monitoring of a production process requires quick and reliable analytical methods and devices. For this purpose, biosensors can be a suitable option, whereas most of the current quality control techniques are time consuming, expensive, and unpractical. In this paper, we describe biosensors developed for analysis of different components present in food samples, namely, glucose, fructose, sucrose, lactose, lactic, malic, acetic, ascorbic, citric and amino acids, ethanol, glycerol, and triglyceride. Biosensors showed desirable sensitivity, selectivity, and response time required for various applications. They are often designed to avoid interference from components present in a complex sample to be analyzed.

“…It was expected that the current response of the carbon-material immobilized electrodes would correlate with the surface area of the electrode. A modification of the carbon materials on the electrode increased the surface area of those electrodes, in comparison with GC electrode (0.067 cm 2 ) 17 . The surface area of the carbon material electrodes was summarized in Fig.…”

Direct oxidation of tryptophan on multi-wall carbon nanotubes modified glassy carbon electrode was examined. Surface poisoning, which was suppression of oxidative current caused from adsorption of oxidized compounds of amino acids through multiple redox scan, was observed on carbon material electrodes (multi-wall carbon nano tube(CNT), carbon powder(CP), Ketjen Black (KB) and glassy carbon(GC). It was found that CNT showed a highly inhibitory effect on the surface poisoning and high current value in the direct oxidation of tryptophan because of a π-π interaction between CNT and indole ring of tryptophan results from orbital mixing. This CNT modified GC electrode was applied to an anode in a fuel cell used with amino acids as fuel. As a result, the maximum of the power density showed 0.36 mW cm -2 at 2.5 mA cm -2 of the current density and 140 mV of the cell voltage.
