“…The detection limit was less than in previous reports, and the linear range of detection was higher 4.5 to 90 µM. Alizadeh et al [ 6 ] synthesized CuO nanorods to mimic laccase activity and obtained a biosensor that could oxidize EP to a colored product with a LOD of 0.31 µM and linear range of 0.6–18 µM. No interference from ascorbic acid, dopamine, and uric acid was observed.…”

The use of sensors in critical areas for human development such as water, food, and health has increased in recent decades. When the sensor uses biological recognition, it is known as a biosensor. Nowadays, the development of biosensors has been increased due to the need for reliable, fast, and sensitive techniques for the detection of multiple analytes. In recent years, with the advancement in nanotechnology within biocatalysis, enzyme-based biosensors have been emerging as reliable, sensitive, and selectively tools. A wide variety of enzyme biosensors has been developed by detecting multiple analytes. In this way, together with technological advances in areas such as biotechnology and materials sciences, different modalities of biosensors have been developed, such as bi-enzymatic biosensors and nanozyme biosensors. Furthermore, the use of more than one enzyme within the same detection system leads to bi-enzymatic biosensors or multi-enzyme sensors. The development and synthesis of new materials with enzyme-like properties have been growing, giving rise to nanozymes, considered a promising tool in the biosensor field due to their multiple advantages. In this review, general views and a comparison describing the advantages and disadvantages of each enzyme-based biosensor modality, their possible trends and the principal reported applications will be presented.

“…The active centers of natural laccase are copper ions. Recently, a number of copper-based nanomaterials, such as copper-nucleotide/DNA coordination compounds, 46–51 copper-amino acid/peptide/protein coordination compounds, 52–56 and other copper-based nanomaterials, 57–62 have been developed to simulate laccase activity. Besides copper-containing nanomaterials, other metal-based nanomaterials have been found to have laccase activity, for example, platinum nanoparticles, 63 manganese oxides, 64 etc.…”
