Microfluidic Rapid Prototype Enzymatic Biofuel Cell Based on a Nanocomposite

Here, a low-cost glucose/O 2 Y-shaped microfluidic biofuel cell was developed using printed circuit board for microelectrode construction. A double-side tape based on the pressure-sensitive adhesive used microchannel fabrication. nanocomposite that consisted of reduced graphene oxide gold nanoparticles (AuNPs), and poly neutral red connected to enzymes applied copper electrode surface. The Aspergillus niger glucose oxidase enzyme Mytheliophthora thermophile laccase were prepare modified anodic cathodic electrodes. Different procedures such as cyclic voltammetry scanning electron microscope coupled with energy-dispersive x-ray spectroscopy (EDX), atomic force microscopy scan SEM/EDX microanalysis displayed structural morphological properties proposed nanocomposite. performance demonstrated maximum power density 36 μW cm −2 , an open-circuit voltage 0.5 V, flow rate 50 μl min −1 . rapid technique RGO/AuNPs/PNR bioelectrodes is good approach finding cells.
