Abstract
NAD+-dependent dehydrogenase-based biosensors usually suffer from the low accuracy due to the interference of cofactors in the complex environment, such as fermentation samples. Herein, we demonstrate the example of an integrated biosensor device that can be applied for analyzing xylose fermentation samples. The device is composed of one chamber for the elimination of NAD+ and NADH in the fermentation broth and another chamber for the sample analysis. In the first chamber, a cyclic voltammetry method coupled with Ni foam as a working electrode was proven to be effective in removing NAD+ and NADH in the fermentation broth. In the other chamber, xylose dehydrogenase, as the recognition element, and diaphorase, used for the regeneration of bioactive NAD+ mediated by vitamin K3, were co-immobilized on the surface of the magnetic nanoparticles, which was further coated onto a magnetic glassy carbon electrode. The detection range of the constructed biosensor was from 0.5 to 10 g L-1 with a detection limit of 0.01 g L-1 at a signal-to-noise ratio of 3. Moreover, the biosensor achieved high selectivity, recovery, reproducibility, and good long-time stability when analyzing real xylose fermentation samples, suggesting its promising application potential.

Abstract
The wide application of xylose in the food, beverage, and pharmaceutical industries, as well as in the booming field of biorefinery, raises the demand for a rapid, accurate, and real-time xylose-sensing technique to rival the conventional methods based on chromatography, spectroscopy, and electrochemical analysis using non-specific enzymes or abiotic catalysts. Herein, a hybrid system comprising polyethylene glycerol swing-arm-tethered NAD+ and xylose dehydrogenase (XDH), coupled with platinum nanoparticles deposited on carbon nanotubes (PtNPs@MWCNTs), was constructed for the real-time sensing of xylose. The use of the PtNPs@MWCNTs composite enhanced the sensitivity of the electric response and reduced the oxidation potential of NADH significantly. Further, the NAD+ immobilization allowed an increase in its microenvironment concentration and facilitated cofactor regeneration. The screen-printed electrode cast with the hybrid system showed a wide xylose detection range of 0.5 to 10 mM or 3.33 to 66.61 mM, and a low detection limit of 0.01 mM or 3.33 mM (S/N = 3), when connected to a potentiostat or a homemade portable biosensor, respectively. The biosensor also exhibited excellent working stability as it retained 82% of its initial performance after 30 days. The analysis of various xylose-containing samples further revealed the merits of our portable xylose biosensor in real-time sensing, including its rapid response, inexpensive instrumentation, and high selectivity, suggesting its great potential in practical applications.
