The enzymatic biofuel cells (EBFCs) are considered as an attractive candidate for powering future implantable medical devices. In this study, a computational model of EBFCs based on three-dimensional (3-D) interdigitated microelectrode arrays was conducted. The main focus of this research is to investigate the effect of different designs and spatial distributions of the microelectrode arrays on...

Biofuel cells (BFCs), which use enzymes as catalysts to harvest energy from green and sustainable fuels abundantly producible from biological systems, are promising next-generation energy devices. However, the poor stability and high specificity to only one fuel type of these bio-catalysts largely limits the practical use of current BFCs. In this contribution, we demonstrate a unique fuel cell ...

conclusions the results of the present investigation suggest that sac could be used as a food supplement in the treatment of diabetes characterized by provoked antioxidant status, altered blood glucose, and hormones level. results the levels of glucose, cyp2e1 activity, thiobarbituric acid reactive substances (tbars), hydroperoxide, and ceruloplasmin were increased significantly; whereas, the l...

Transgenic Panicum virgatum L. silencing (KD) or overexpressing (OE) specific genes or a small RNA (GAUT4-KD, miRNA156-OE, MYB4-OE, COMT-KD and FPGS-KD) was grown in the field and aerial tissue analysed for biofuel production traits. Clones representing independent transgenic lines were established and senesced tissue was sampled after year 1 and 2 growth cycles. Biomass was analysed for wall s...

The determination of cholesterol is greatly important because high concentrations this biomarker are associated to heart disease. Moreover, can be used as a fuel in enzymatic cells operating under physiological conditions. Here, we present biosensor and peroxide-free biofuel cell based on the electrocatalytic oxidation NADH generated during reaction dehydrogenase (ChDH) an alternative H2O2 bios...

A simple energy harvesting strategy has been developed to selectively catalyze glucose in the presence of oxygen in a glucose/O2 fuel cell. The anode consists of an abiotic catalyst Al/Au/ZnO, in which ZnO seed layer was deposited on the surface of Al/Au substrate using hydrothermal method. The cathode is constructed from a single rod of platinumwith an outer diameter of 500 mm. The abiotic glu...

The use of plant biomass for biofuel production will require efficient utilization of the sugars in lignocellulose, primarily glucose and xylose. However, strains of Saccharomyces cerevisiae presently used in bioethanol production ferment glucose but not xylose. Yeasts engineered to ferment xylose do so slowly, and cannot utilize xylose until glucose is completely consumed. To overcome these bo...

The enzyme-based keypad lock was integrated with a biofuel cell yielding a self-powered biomolecular information security system. The correct "password" introduced into the keypad lock resulted in the activation of the biofuel cell, while all other "wrong" permutations of the enzyme inputs preserved the "OFF" state of the biofuel cell.
