“…The sensor can be characterized by high sensitivity and selectivity for rutin (LR of 1 to 120 µM and LOD of 0.4 µM) and catechol (LR of 10 to 600 µM) (Table 11) that is better compared to laccase-based biosensors. Garcia and coauthors [272] reported the construction of a CPS2 (copper oxide-based carbon paste) biomimetic sensor for phenol, rutin and catechol determination in natural samples, such as dried extracts of red fruits and coffee. The enhanced sensitivity towards catechol as a model substrate correlated to the amount of incorporated copper oxide, resulting in improvement of electroactive surface area and electrocatalytic ability os the sensor.…”

The current review is devoted to nanozymes, i.e., nanostructured artificial enzymes which mimic the catalytic properties of natural enzymes. Use of the term “nanozyme” in the literature as indicating an enzyme is not always justified. For example, it is used inappropriately for nanomaterials bound with electrodes that possess catalytic activity only when applying an electric potential. If the enzyme-like activity of such a material is not proven in solution (without applying the potential), such a catalyst should be named an “electronanocatalyst”, not a nanozyme. This paper presents a review of the classification of the nanozymes, their advantages vs. natural enzymes, and potential practical applications. Special attention is paid to nanozyme synthesis methods (hydrothermal and solvothermal, chemical reduction, sol-gel method, co-precipitation, polymerization/polycondensation, electrochemical deposition). The catalytic performance of nanozymes is characterized, a critical point of view on catalytic parameters of nanozymes described in scientific papers is presented and typical mistakes are analyzed. The central part of the review relates to characterization of nanozymes which mimic natural enzymes with analytical importance (“nanoperoxidase”, “nanooxidases”, “nanolaccase”) and their use in the construction of electro-chemical (bio)sensors (“nanosensors”).

“…The immobilization of laccase enzymes on the surfaces of different materials to constitute a biosensing platform is however, a critical factor in the development of bioelectrochemical sensing devices. In this sense, copper oxide nanoparticles, nanocomposites containing molybdenum disulfide, graphene quantum dots and ionic liquid membranes have become compatible matrices for laccase immobilization in biosensing devices.…”

The application of enzymes offers an enormous potential in the improvement of existing industrial procedures and in the establishment of new processes for obtaining high-added value products. Enzymes provide cleaner and more efficient industrial processes and contribute to the sustainability concept. In this sense, laccases are very versatile biocatalysts currently used in food, textile and pulp and paper sectors among others. During the last years, scientific efforts have been diverted to the exploitation of such interesting enzymes in novel fields like lignocellulosic biorefineries, biosensors or enzymatic biofuel cells. This review provides a general vision of the use of laccase enzymes describing their main characteristics and mode of action. Furthermore, their current uses in industrial processes are summarized and the most novel potential application of laccases are revealed. The increasing interest on laccases is also demonstrated by the research efforts on enzyme engineering as it is detailed in this review. wileyonlinelibrary.com/jctb www.soci.org AD Moreno et al.

Natural products (NPs) are a valuable source in the food, pharmaceutical, agricultural, environmental, and many other industrial sectors. Their beneficial properties along with their potential toxicities make the detection, determination or quantification of NPs essential for their application. The advanced instrumental methods require time-consuming sample preparation and analysis. In contrast, biosensors allow rapid detection of NPs, especially in complex media, and are the preferred choice of detection when speed and high throughput are intended. Here, we review diverse biosensors reported for the detection of NPs. The emerging approaches for improving the efficiency of biosensors, such as microfluidics, nanotechnology, and magnetic beads, are also discussed. The simultaneous use of two detection techniques is suggested as a robust strategy for precise detection of a specific NP with structural complexity in complicated matrices. The parallel detection of a variety of NPs structures or biological activities in a mixture of extract in a single detection phase is among the anticipated future advancements in this field which can be achieved using multisystem biosensors applying multiple flow cells, sensing elements, and detection mechanisms on miniaturized folded chips.
