“…A typical heavy metal analysis is performed using conventional spectroscopic techniques, such as atomic absorption spectrometry (AAS) and inductively coupled plasma optical mass spectrometry (ICP-MS). However, electrochemical methods offer significant advantages over optical analytical techniques, including low cost, simplicity, and the possibility of field applications [ 54 ]. Several electrochemical biosensors for the quantitative detection of As, Hg 2+ , Cd 2+ , Pb 2+ , Cu 2+ , and Zn 2+ were discussed below ( Table 6 ).…”

Food safety issues are directly related to people’s quality of life, so there is a need to develop efficient and reliable food contaminants’ detection devices to ensure the safety and quality of food. Electrochemical biosensors have the significant advantages of miniaturization, low cost, high sensitivity, high selectivity, rapid detection, and low detection limits using small amounts of samples, which are expected to enable on-site analysis of food products. In this paper, the latest electrochemical biosensors for the detection of biological contaminants, chemical contaminants, and genetically modified crops are reviewed based on the analytes of interest, electrode materials and modification methods, electrochemical methods, and detection limits. This review shows that electrochemical biosensors are poised to provide miniaturized, specific, selective, fast detection, and high-sensitivity sensor platforms for food safety.

“…Analyzing recent literature (because the author has not studied the nervous tissues of fish since 2015 (Gradov, 2015), due to the lack of equipment and infrastructural capabilities to maintain them), we came to a paradoxical, in fact, conclusion. Despite the increase in works postulating the toxic effect of mercury demonstrated on fish (up to its toxicokinetics and biotransformation at various stages of this effect) and works postulating mercury contamination under various hydrochemical conditions (Zheng et al, 2019;Jinadasa and Fowler, 2019;Wang and Wang, 2019;Mendes et al, 2019;Lahrich and El ABSTRACT. The role of mercury in the development of various neuropathologies is well known.…”

Abstract. The role of mercury in the development of various neuropathologies is well known. The biogeochemical cycles of mercury indicate the possibility of its introduction into various organisms (including humans) through the corresponding trophic chains. However, as it turns out from the literature analysis, until recent years, there have been almost no works on the dynamic microscopic study (either in situ or in vivo) of the processes of connectome involution in aquatic organisms (including fishes, marine mammals, etc.) under the action of mercury. In this regard, we attempted to study the dynamics of morphogenesis and breakdown of the emerging connectome under the mercury exposure. A dynamic study of frames with the dynamics of the axonal path search was carried out in a series with an address-time code, on which it is possible to track the vector fields of displacements and reaction-diffusion processes in the cell culture immediately after the introduction of a drop of mercury or a mercury-containing liquid using capillary pipettes. This paper describes the observed effects and the possible mechanisms underlying them.

“…Lead, as one of the greatest toxic heavy metallic pollutants, affects the functions of the central and peripheral nervous system, cardiovascular system, reproductive system and immune system, and causes gastrointestinal tract, liver, kidney and brain diseases. [1][2][3][4] Therefore, different countries, regions and organizations have set various sanitary standards for lead. For example, the World Health Organization (WHO) has designated lead as one of the ten chemicals that have caused major public health concerns, and has set a maximum allowable lead concentration of 48 nmol l −1 in drinking water.…”

Herein, a dual-mode aptasensor for subnanomolar detection of lead ions Pb 2+ based on electrochemiluminescence (ECL) and fast scan voltammetry (FSV) was developed. It could be one-step fabricated using an all-in-one probe Fe 3 O 4 @Au-ssDNA&Ru-NH 2 which has multiple functions: Fe 3 O 4 core achieves one-step preparation of the aptasensor; Au shell provides a place for assembly and electrochemical reactions; ssDNA can selectively recognize and capture target Pb 2+ , and ferrocene labeled on it could provide fast scan voltammetric signal and participate in changes of ECL signals; and Ru-NH 2 is a signal marker for ECL detection. In presence of target Pb 2+ , ssDNA folds to form G-quadruplex, and ferrocene labeled on its end approaches to the Au shell surface resulting in easier electron transfer. So the electrochemical signal is enhanced, and ECL quenching occurs. Electrochemical peak current increased about 1000 times at 100 V s −1 using FSV, making its sensitivity compatible with that of ECL to obtain highly sensitive dual-mode detection. Pb 2+ could be detected in the concentration range from 10 −10 mol l −1 to 10 −6 mol l −1 with a limit of quantitation (LOQ) 10 −10 mol l −1 . Selectivity, stability, reproducibility, accuracy and practicality are good. This extremely simple method provides a valuable idea for developing biosensors for field detection applications.
