“…Indeed, recent advances in the eld of EBFCs have been driven mainly by the design and assembly of three-dimensional (3D) porous and high surface-area electrode materials. 13,14 However, these bioelectrodes can hardly be integrated into blood or other biological vessels. Additionally, for biological tests they require a membrane to prevent clogging by blood cells and possible formation of cholesterol plaques or other structures that could affect the blood circulation and induce thrombosis or embolism.…”

The proposed work intended to make an intellectual contribution to the domain of green nanotechnology which emphasizes the chemical synthesis of a conducting nanocomposite based on the incorporation of gold nanoparticles (Au) into the redox matrix of polyindole (PIn) along with the subsequent improvement in the overall properties of the composite by the addition of sulfonated graphene oxide (SGO). The bioanode was developed by the deposition of the PIn-Au-SGO nanocomposite with subsequent immobilization of ferritin (Frt) and glucose oxidase (GOx) on the glassy carbon electrode (GC). The successful application of the PIn-Au-SGO nanocomposite toward the development of a ferritin-mediated glucose biofuel cell anode was studied by the electrochemical characterization of the constructed bioanode (GC-PIn-Au-SGO/Frt/GOx) for the bioelectrocatalytic oxidation of glucose. The maximum current density obtained by the modified bioanode was found to be 17.8 mA cm−2 at the limiting glucose concentration of 50 mM in 0.1 M K4Fe(CN)6 at a scan rate of 100 mVs−1. The lifetime of the concerned bioelectrode when stored at 4 °C was estimated to be 53 days approximately. The appreciable results of the structural and electrochemical characterization of the PIn-Au-SGO based bioelectrode reveal its potential applications exclusively in implantable medical devices.

The key challenge for the broad application of implantable biofuel cells (BFCs) is to achieve inorganicorganic composite biocompatibility while improving the activity and selectivity of the catalysts.W eh ave fabricated nanoengineered red blood cells (NERBCs) by an environmentally friendly method by using red blood cells as the raw material and hemoglobin (Hb) embedded with ultrasmall hydroxyapatite (HAP,C a 10 (PO 4 ) 6 (OH) 2 )a st he functional BFC cathode material. The NERBCs showed greatly enhanced cell performance with high electrocatalytic activity,s tability, and selectivity.T he NERBCs maintained the original biological properties of the natural cell, while enhancing the catalytic oxygen reduction reaction (ORR) through the interaction between À OH groups in HAP and the Hb in RBCs.They also enabled direct electron transportation, eliminating the need for an electron-transfer mediator,a nd showed catalytic inactivity for glucose oxidation, thus potentially enabling the development of separator-free BFCs.Enzyme biofuel cells (EBFCs) [1] have attracted considerable attention as micro- [2] or even nanoscale power [3] sources for implantable biomedical devices,s uch as cardiac pacemakers, [4] implantable self-powered sensors, [5] and biosensors for monitoring physiological parameters. [6] There are two types of EBFCs,w hich differ in the operating mechanism;n amely, mediated electron transfer (MET) [7] and direct electron transfer (DET) [8] EBFCs.M ET EBFCs rely heavily on redox mediators to shuttle electrons between biocatalytic active sites and electrode surfaces,w hereas DET EBFCs enable electron transfer from the enzyme active sites directly to the electrode. [9] In either case,t he other electrode (cathode) requires an oxygen-reduction catalyst, such as laccase [10] or bilirubin oxide (BOD), [11] to facilitate the oxygen reduction reaction (ORR). Unfortunately,i ng eneral, the current catalysts under investigation show very low catalytic performance as well as poor adhesion to the electrode surface. Such drawbacks drastically limit the practical application of EBFCs. [12] Although approaches such as electrode nanomodification, [1b] enzyme immobilization, [13] and redox-mediator addition [14] have been intensively investigated to facilitate electron transfer between enzymes and electrodes,t hey usually face some challenges,s uch as avoiding the deformation and inactivation of enzymes, [15] preventing nanotoxicity, [16] or improving the stability of the cell.
