“…As immobilization matrixes for laccase‐based biosensors and bioreactors, carbon nanomaterials (Liu et al, 2007), metal nanoparticles (Chen et al, 2015), metal oxides (Chawla et al, 2012), electroconductive polymers (Rahman et al, 2008), and ionic liquids (Franzoi et al, 2009) are successfully used. The peculiarity of nanocomposite materials as carriers for laccase immobilization is their large specific surface area and good biocompatibility, which resulted in improved sensitivity, good selectivity, stability, repeatability, and reproducibility of biosensors (Castrovilli et al, 2019; Zerva et al, 2019; Zhang et al, 2020). In particular, electrode construction with carbon nanotubes, fullerene (C 60 ), graphene, and other carbon materials to increase surface area and conductivity has been attempted (Dong et al, 2017).…”

“…Laccase, being multi‐copper oxidase with simple structure and specific function, is a promising biocatalyst for bioreactors and electrochemical devices—biosensors and enzymatic biofuel cells. The enzyme play a special role as biorecognition element in biosensors for detection of toxic pollutants of phenolic nature (Rodríguez‐Delgado et al, 2015; Yashas et al, 2018; Zhang et al, 2018; Campaсa et al, 2019; Kavetskyy et al, 2019; Mohtar et al, 2019; Patel et al, 2019; Zhang et al, 2020) and designing of biofuel cells (Kudanga and Le Roes‐Hill, 2014; Kang et al, 2018; Ghosh et al, 2019; Han et al, 2019; Zerva et al, 2019; Zhang et al, 2019).…”

Laccases are enzymes belonging to the family of blue copper oxidases. Due to their broad substrate specificity, they are widely used in many industrial processes and environmental bioremediations for removal of a large number of pollutants. During last decades, laccases attracted scientific interest also as highly promising enzymes to be used in bioanalytics. The aim of this study is to obtain a highly purified laccase from an efficient fungal producer and to demonstrate the applicability of this enzyme for analytics and bioremediation. To select the best microbial source of laccase, a screening of fungal strains was carried out and the fungus Monilinia fructicola was chosen as a producer of an extracellular enzyme. Optimal cultivation conditions for the highest yield of laccase were established; the enzyme was purified by a column chromatography and partially characterized. Molecular mass of the laccase subunit was determined to be near 35 kDa; the optimal pH ranges for the highest activity and stability are 4.5–5.0 and 3.0–5.0, respectively; the optimal temperature for laccase activity is 30°C. Laccase preparation was successfully used as a biocatalyst in the amperometric biosensor for bisphenol A assay and in the bioreactor for bioremediation of some xenobiotics.

The research field of glucose biosensing has shown remarkable growth and development since the first reported enzyme electrode in 1962. Extensive research on various immobilization methods and the improvement of electron transfer efficiency between the enzyme and the electrode have led to the development of various sensing platforms that have been constantly evolving with the invention of advanced nanostructures and their nano-composites. Examples of such nanomaterials or composites include gold nanoparticles, carbon nanotubes, carbon/graphene quantum dots and chitosan hydrogel composites, all of which have been exploited due to their contributions as components of a biosensor either for improving the immobilization process or for their electrocatalytic activity towards glucose. This review aims to summarize the evolution of the biosensing aspect of these glucose sensors in terms of the various generations and recent trends based on the use of applied nanostructures for glucose detection in the presence and absence of the enzyme. We describe the history of these biosensors based on commercialized systems, improvements in the understanding of the surface science for enhanced electron transfer, the various sensing platforms developed in the presence of the nanomaterials and their performances.

“…prepared aloe‐like ZnO nanocrystals using a hydrothermal method and subsequently deposited AuNPs on the ZnO surface to form aloe‐like Au−ZnO arrays. The synergic effect of the prepared nanocomposite promoted the immobilization of laccase (Lac) for the specific sensing of CT. Zhang and co‐workers [99] prepared a biosensor based on laccase, Nafion, MoS 2 , and AuNPs, for CT detection. The proposed biosensor (AuNPs‐MoS 2 ‐Lac/GCE) displayed good selectivity and enhanced peak current toward CT (Figure 9).…”

The high surface‐to‐volume ratio and desirable chemical, thermal, and catalytic properties of nanomaterials have made them promising electrode materials for sensing applications. As such, different nanomaterials and their nanocomposite‐based individual and/or simultaneous detection of dihydroxybenzene (DHB) have been reported in recent years. Due to the low degradation rate and high toxicity of DHB isomers, the development of innovative and robust sensors for their simultaneous detection has received considerable attention. In this review, applications of different nanomaterials (with the exception of carbon nanotubes, graphene, and their derivatives) for individual and/or simultaneous detection of DHB are briefly discussed. The focal point is on the characteristic features of the modified electrodes that improve their electrocatalytic activities toward DHB. Real sample analysis and electrolyte media are also summarized. This review includes studies published from 2011 to 2020.
