“…However, in a recent study using sonication as an accelerator mechanism, An et al ( 2015) [253] reduced this time to just 5 minutes. Many authors used this method to confirm the proposed protocol's efficiency and efficacy [253,254,[256][257][258]. Figure 7 shows how the process for enzyme immobilization by hybrid nanoflowers occurs: Figure 7.…”

“…In addition to this aspect, there is usually an increase in enzyme tolerance by various reactional media, such as organic solvents, and also the primary foundation of immobilization facilitated reuse of the biocatalyst in several reactions cycles [247,248,250]. The synthesis of hybrid nanoflowers is usually straightforward, composed of a reaction of active organic enzymes/molecules and metal ions in aqueous phosphate buffer, usually at pH 7 and 25 • C, generating a hierarchically structured compound with a wide surfaceto-volume ratio, retaining a large part of the biomolecules without severe mass transfer limitations [249,250,256]. The preparation typically takes three to five days.…”

The market for industrial enzymes has witnessed constant growth, which is currently around 7% a year, projected to reach $10.5 billion in 2024. Lipases are hydrolase enzymes naturally responsible for triglyceride hydrolysis. They are the most expansively used industrial biocatalysts, with wide application in a broad range of industries. However, these biocatalytic processes are usually limited by the low stability of the enzyme, the half-life time, and the processes required to solve these problems are complex and lack application feasibility at the industrial scale. Emerging technologies create new materials for enzyme carriers and sophisticate the well-known immobilization principles to produce more robust, eco-friendlier, and cheaper biocatalysts. Therefore, this review discusses the trending studies and industrial applications of the materials and protocols for lipase immobilization, analyzing their advantages and disadvantages. Finally, it summarizes the current challenges and potential alternatives for lipases at the industrial level.

“…Catalase-like nanozymes cannot be utilized solely for glucose biofuel cell development; however, bi-enzymatic nanozymes showing GOx and catalase have been reported to serve as an anode in glucose biofuel cells [ 45 , 46 ]. In this regard, finding efficient catalase-like nanozymes or bi-enzymatic nanozymes showing both GOx and catalase-like activity, for preparing an efficient anode in glucose biofuel cells is crucial for decomposing the byproduct H 2 O 2 and enhancing the power output and extending the lifetime of glucose-based NBFCs.…”

The appearance and evolution of biofuel cells can be categorized into three groups: microbial biofuel cells (MBFCs), enzymatic biofuel cells (EBFCs), and enzyme-like nanomaterial (nanozyme)-based biofuel cells (NBFCs). MBFCs can produce electricity from waste; however, they have significantly low power output as well as difficulty in controlling electron transfer and microbial growth. EBFCs are more productive in generating electricity with the assistance of natural enzymes, but their vulnerability under diverse environmental conditions has critically hindered practical applications. In contrast, because of the intrinsic advantages of nanozymes, such as high stability and robustness even in harsh conditions, low synthesis cost through facile scale-up, and tunable catalytic activity, NBFCs have attracted attention, particularly for developing wearable and implantable devices to generate electricity from glucose in the physiological fluids of plants, animals, and humans. In this review, recent studies on NBFCs, including the synthetic strategies and catalytic activities of metal and metal oxide-based nanozymes, the mechanism of electricity generation from glucose, and representative studies are reviewed and discussed. Current challenges and prospects for the utilization of nanozymes in glucose biofuel cells are also discussed.

“…Because CNTs demonstrated high mechanical strength, high thermal and electrical conductivity and adsorption, unique nanostructure, mechanical and thermal properties, and hydrophobicity, many researchers applied CNTs as templates to support for heterogeneous catalysts [29]. Hybrid nanoflower composites mixed with CNTs showed high enzyme wiring efficiency and electron transfer rate which could be used in the field of fabricating enzymatic biofuel cells [30]. In addition, Esumi’s group explored the dendrimer-encapsulated Au NPs for 4-NP reduction, but the results showed the process influenced by the concentration and generation of the dendrimers [13, 31–33].…”

The effective synthesis and self-assembly of nanocomposites were of key importance for a broad range of nanomaterial applications. In this work, new carbon nanotube (CNT)-Cu 2 O nanocomposites were successfully synthesized via a facile approach. CNT was selected as the anchoring substrate to load Cu 2 O nanoparticles to prepare composite catalysts with well stability and good reusability. It is discovered that the prepared CNT-Cu 2 O nanocomposite materials could be effectively controlled via regulating preparation temperature and time without the use of any stabilizing agents. The nanostructures of synthesized composites were well characterized by many techniques, such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). And the prepared CNT-Cu 2 O nanocomposites with optimized preparation conditions as new catalyst displayed excellent catalytic performance on the reduction reaction of p-nitrophenol, demonstrating potential applications for environmental governance and composite materials.
