“…The laccase-like activity of the nanozyme was so efficient to yield even a four-order higher catalytic efficiency than that of natural laccase, presumably due to the presence of more active sites than natural laccase. Similarly, nanozymes having the active site-mimicking structures coordinated with Cu with cysteine-aspartic acid dipeptide or DNA-copper hybrid nanoflowers were also reported to exhibit laccase-like activity, which was higher and more stable than that of the natural counterpart [ 48 , 49 ].…”

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.

“…However, relying on the self-assembly of copper ions and DNA, the authors have successfully fabricated a novel copper hybrid nanoflower, which induces a new paper-based microfluidic device. This device has displayed effective application for the colorimetric detection of catechol, dopamine, and hydroquinone [20]. In addition, UV/Vis detection of 2,4-dichlorophenol has been successfully performed using an enzyme mimic that has been well-synthesized by Cu ion and adenosine monophosphate [71].…”

“…Recently, various optical sensor techniques have been developed, such as colorimetric [19,20], fluorescence [21,22], LSPR phenomenon [23,24], and plasmon-enhanced surface enhanced Raman scattering (SERS) [25][26][27]. Among these techniques, the SERS method based on plasmonic resonance nanomaterials is promising because of its high specific, selective, and sensitive detection capability.…”

Many scientists are increasingly interested in on-site detection methods of phenol and its derivatives because these substances have been universally used as a significant raw material in the industrial manufacturing of various chemicals of antimicrobials, anti-inflammatory drugs, antioxidants, and so on. The contamination of phenolic compounds in the natural environment is a toxic response that induces harsh impacts on plants, animals, and human health. This mini-review updates recent developments and trends of novel plasmonic resonance nanomaterials, which are assisted by various optical sensors, including colorimetric, fluorescence, localized surface plasmon resonance (LSPR), and plasmon-enhanced Raman spectroscopy. These advanced and powerful analytical tools exhibit potential application for ultrahigh sensitivity, selectivity, and rapid detection of phenol and its derivatives. In this report, we mainly emphasize the recent progress and novel trends in the optical sensors of phenolic compounds. The applications of Raman technologies based on pure noble metals, hybrid nanomaterials, and metal–organic frameworks (MOFs) are presented, in which the remaining establishments and challenges are discussed and summarized to inspire the future improvement of scientific optical sensors into easy-to-operate effective platforms for the rapid and trace detection of phenol and its derivatives.

“…It was determined that NFs obtained by the coordination of Bovine Serum Albumin (BSA) and Zn ion in PBS medium can absorb Cu ions [7]. Tran et al, (2021) suggested that DNAbased Cu NFs could be used as sensors for the detection of phenolic compounds [8]. They also reported that the obtained DNA-NFs could catalyze the neutral red dye.…”

Hybrid nanoflowers (hNFs), which are widely used in enzyme purification and catalytic activity applications, consist of organic and inorganic components. In this study, hNFs were synthesized in PBS buffer (pH: 5-9) by using different volume of Ascoseria mirabilis algae extract (0.65 ml, 1 ml and 1.65 ml) instead of expensive and difficult to obtain molecules such as enzymes and DNA for the synthesis process. According to the FE-SEM images, the morphology and diameters of the petals and NFs differ depend to the pH of the PBS buffer (synthesis did not occur at pH 5) and the volume of extract used. The catalytic and antioxidant properties of NFs synthesized with the used bioextract under optimum conditions (pH: 7.4, 1 ml extract) where a complete flower formation was observed were evaluated. The presence of Cu element and other components was detailed with EDX mapping. The peaks obtained by FT-IR analysis and the existence of functional groups that play a role in the synthesis are discussed. According to the results of the characterization tests, hNFs were synthesized by a cheap and eco-friendly with the coordination of Cu element and A. mirabilis extract in PBS buffer. Cu NFs exhibited peroxidase like catalytic activity against guaiacol, and antioxidant activity. The activities of hNFs is based on a Fenton-like mechanism. It is thought that this study will shed light on hNFs synthesis and catalytic activity application studies with bioextracts instead of biomolecules obtained by expensive and complex processes.
