“…Fructose dehydrogenase is an example of enzyme working at the anode in a mediatorless regime as we demonstrated in a recent communication. 35 At present, the system lifetime, shorter than that of common batteries, is limited primarily by the inability of the enzymes to regenerate sufficiently fast. Additionally, the enzymes are prone to denaturation under constant load conditions.…”

Carbon paper covered with side-naphthylated multi-walled carbon nanotubes was used as the conducting support for the construction of a biocathode in a hybrid biofuel cell (biobattery). Laccase Cerrena unicolor enzyme was employed as the catalyst for the 4e reduction of oxygen and a zinc disc covered with hopeite was used as the anode. Derivatized carbon nanotubes increase the working surface of the electrode and provide direct contact with the active sites of laccase. Biobattery characteristics under externally applied resistance, and power-time dependencies under flow cell conditions were evaluated. The system including the sandwich biobattery powering a dedicated two-electrode minipotentiostat with a simple sensor electrode was employed for monitoring a model neurotransmitter-catechol. The biobattery-powered sensor yielded the oxidation currents linearly dependent on catechol concentration in the range 0-2 mM and with a correlation coefficient of 0.998. This type of biobattery with laccase as the cathode catalyst can be integrated with analytical devices and power them even in long-time monitoring experiments. Biofuel cells (BFC) and hybrid biofuel cells (biobatteries) have several advantages over conventional fuel cells, e.g. they use enzymesvery efficient catalysts to transform chemical energy to electrical energy. The attractiveness of biofuel cells is due to possibilities of variety of applications of high energy density biofuels such as ethanol, glycerol and carbohydrates, work at room temperatures, at pH close to neutral and the products of reactions are environmentally-friendly. [1][2][3][4] Enzymes are also less expensive than metallic catalysts used in conventional fuel cells and additionally are specific and selective, therefore do not require membrane separating electrode compartments. The biofuel cell can work as open-type device, and can be easily miniaturized. 4 Initial market opportunities for biofuel cells are likely to be where there is a need for large amounts of energy but low power demands. This is because biofuel cells can achieve high efficiencies for oxidizing a given fuel, providing high energy density, but have lower power densities due to lower catalytic activity compared to metal catalyst based fuel cells.3 An important area of applications of the biofuel cells is powering electronic devices, e.g. clocks, timers or toys, small medical devices such as biosensors and drug delivery systems. 5-9The number of enzyme molecules that can be directly bound to the conductive support is rather low, due to their large size leading to small surface concentration of catalytic active sites per electrode geometric area. Therefore application of a three dimensional conductive matrix is required. Carbon nanotubes increase the working surface area of the electrode and improve conductivity of the film. Furthermore, carbon nanotubes modified with different aryl groups provide easier access to the enzyme active sites and allow working in the direct electron transfer regime without any mediators.

“…It has been demonstrated that polypyrrole can be homogeneously coated on nanocellulose fibers by a chemical polymerization‐induced adsorption process. Recently, it was recorded that the nanocellulose–polypyrrole composites can be fabricated by in situ polymerization on the individual nanocellulose fibers . The large surface area of nanocellulose ensured the attainment of a relatively high specific charge capacity, whereas the continuous nano‐metric layer of polypyrrole on the individual nanocellulose enabled the polypyrrole layers to undergo oxidation and reduction at high rates (Fig.…”

In this review, a recent prospect on application of nanocellulose in energy application has been highlighted. To achieve high capacities that are essential for effective extraction of interesting ions and for faster charging and discharging in the energy storage devices, nanocellulose in the conducting matrix must obviously assist the dual purpose of mechanically improving and reinforcing the specific charge capacity. The abundant number of nanocellulose hydroxyl groups on the surface favors the formation of hydrogen bonding in an ordered structure and lead to it having high strength and stiffness properties at low density. This brought up the idea of utilizing nanocellulose as a reinforcement and energy adsorption agent originating from the possibility of exploiting the high strength and stiffness of cellulose crystals in composite applications.

“…The modification of nanocellulose was performed by oxidation using the dehydrogenase enzyme. Nanocellulose/polypyrrole composites provide large catalytic oxidation currents, due to the large effective surface area of the composite material, and enables storing of the charge . Furthermore, direct oxidation of nanocellulose has been performed using the enzyme galactose oxidase (EC 1.1.3.9) followed by selective carboxylation (Fig.…”

Nanocellulose is an emerging sustainable biomaterial with exceptional physicochemical properties. It can be isolated from inexpensive renewable cellulosic biomass. Wood cellulose is the most extensively used biomass for the isolation of nanocellulose. Yet, owing to their hydrophilic nature, their utilization is restricted to applications involving hydrophilic or polar media, which limits their exploitation. With the presence of a large number of chemical functionalities within their structure, these building blocks provide a unique platform for significant surface modification through various methods. On the other hand, significantly used hazardous chemicals make the process environmentally unfriendly. Furthermore, recovery of used chemicals and toxicity of final products are the biggest challenges. To overcome these problems, the enzymatic approach is an emerging trend for isolation and surface modification of nanocellulose. This review assembles current knowledge in the research and development of nanocelluloses from cellulosic biomass and emphasizes the enzymatic routes developed so far for isolation, production, and functionalization.
