“…Screen-printed electrodes have also been used to enhance the attachment of microorganisms on the surface of working electrodes . For instance, Hua and co-workers recently reported a disposable electrochemical enzymatic biosensor utilizing screen-printed carbon electrodes for the amperometric detection of organophosphorus pesticides . Acetylcholine esterase was immobilized onto a screen-printed carbon electrode modified with multiwalled carbon nanotubes, chitosan, and gold nanoparticles, achieving high sensitivity due to synergistic effects between carbon nanotubes and gold nanoparticles.…”

Bioelectrocatalysis is an interdisciplinary research field combining biocatalysis and electrocatalysis via the utilization of materials derived from biological systems as catalysts to catalyze the redox reactions occurring at an electrode. Bioelectrocatalysis synergistically couples the merits of both biocatalysis and electrocatalysis. The advantages of biocatalysis include high activity, high selectivity, wide substrate scope, and mild reaction conditions. The advantages of electrocatalysis include the possible utilization of renewable electricity as an electron source and high energy conversion efficiency. These properties are integrated to achieve selective biosensing, efficient energy conversion, and the production of diverse products. This review seeks to systematically and comprehensively detail the fundamentals, analyze the existing problems, summarize the development status and applications, and look toward the future development directions of bioelectrocatalysis. First, the structure, function, and modification of bioelectrocatalysts are discussed. Second, the essentials of bioelectrocatalytic systems, including electron transfer mechanisms, electrode materials, and reaction medium, are described. Third, the application of bioelectrocatalysis in the fields of biosensors, fuel cells, solar cells, catalytic mechanism studies, and bioelectrosyntheses of high-value chemicals are systematically summarized. Finally, future developments and a perspective on bioelectrocatalysis are suggested.

“…In recent years, AuNPs have been used for electrochemical sensors for the detection of pesticides as shown in Table 4 . Several AuNPs based electrochemical biosensors have been described in the literature by using AChE enzyme [ 154 , 155 ]. Dong et al [ 154 ] developed an AChE sensor for the detection of malathion and parathion methyl in cabbage and water samples based on a film of AuNPs/three-dimensional graphene.…”

Pesticides are a family of non-biodegradable chemical compounds which widely used in agriculture to control pests and increase yield production. However, overuse or abuse of pesticides and their metabolites may cause potential toxicity for the environment as well as human health and all other living organisms, even at deficient concentrations. Consequently, the development of sensors for monitoring these compounds is significant. Recently, nanoparticles-based sensors have been extensively employed as a potential alternative or complementary analytical tool to conventional detection methods for pesticides. Among them, gold nanoparticles (AuNPs) owing to their unique optical properties have been developed as smart sensors with high selectivity, sensitivity, simplicity, and portability. These comprehensive reviews have summarized various studies performed based on different detection strategies, i.e., colorimetric, fluorescence, surface-enhanced Raman scattering, and electrochemical, using AuNPs as sensing probes for pesticide analysis in various matrices. Additionally, the current challenges and future trends for developing novel AuNPs-based sensors for the detection of pesticides are also discussed.

“…Hua, Ruecha, Hiruta, and Citterio (2019) developed a disposable enzymatic electrochemical biosensor based on a screen‐printed carbon electrode platform to analyze amperometric organophosphorus pesticide (OPs). Two linear dynamic response ranges were observed for paraoxon‐ethyl, from 0.01 to 10 μg/L and from 10 to 100 μg/L, with an LOD of 0.03 μg/L.…”
