“…A suitable electrolyte separates both electrodes. The presence of a target analyte generates electrochemical signals which are used to monitor the concentration of the analyte ( Kaya et al, 2021 ). These types of sensing systems provide high selectivity, low power requirements, linear and stable output, excellent accuracy, repeatability, and economical sensing.…”

Endocrine-disrupting chemicals (EDCs) are a class of man-made substances with potential to disrupt the standard function of the endocrine system. These EDCs include phthalates, perchlorates, phenols, some heavy metals, furans, dimethoate, aromatic hydrocarbons, some pesticides, and per- and polyfluoroalkyl substances (PFAS). EDCs are widespread in the environment given their frequent use in daily life. Their production, usage, and consumption have increased many-fold in recent years. Their ability to interact and mimic normal endocrine functions makes them a potential threat to human health, aquatics, and wild life. Detection of these toxins has predominantly been done by mass spectroscopy and/or chromatography-based methods and to a lesser extent by advanced sensing approaches such as electrochemical and/or colorimetric methods. Instrument-based analytical techniques are often not amenable for onsite detection due to the lab-based nature of these detecting systems. Alternatively, analytical approaches based on sensor/biosensor techniques are more attractive because they are rapid, portable, equally sensitive, and eco-friendly. Advanced sensing systems have been adopted to detect a range of EDCs in the environment and food production systems. This review will focus on advances and developments in portable sensing techniques for EDCs, encompassing electrochemical, colorimetric, optical, aptamer-based, and microbial sensing approaches. We have also delineated the advantages and limitations of some of these sensing techniques and discussed future developments in sensor technology for the environmental sensing of EDCs.

“…Neutrophil forms vary greatly, comprising serotonin, glutamate, DM, aminobutyric acid, epinephrine, acetylcholine, and norepinephrine, to name just a few. In many physical exercises, the relevance of DM in maintaining health, including hormonal, cardiovascular, mood, mobility, memory, and behavior, is essential. − Stress, emotional processes in human metabolism, neurological issues, paraganglioma tumors, and neuroblastoma tumors are only a few of the pathological conditions that the monoamine of DM is used to treat. Human blood typically contains from 0.01 to 1.00 μM of DM .…”

The spinel type of metal oxide decoration with a heteroatom (N)-doped mesoporous carbon hollow sphere offers an excellent electrocatalyst and increases the probability of survival in detection of sensor applications. Here, we develop a single-step and effective hard template strategy for the excellent detection of dopamine (DM) with the utilization of the cobalt precursor cobalt phthalocyanine (CoPc). The optimum 0.2 g-loaded CoPc and the resulting cobalt oxide (Co 3 O 4 )-anchored nitrogen-doped hollow carbon sphere (Co 3 O 4 /NDHCS-0.2) material demonstrate the admirable sensing performance toward DM detection. The remarkable sensing performance is mainly ascribed to the stable mesoporous hollow carbon sphere and its better thickness, large surface area, defect sites, higher decoration of Co content, and higher concentrations of octahedral Co 3+ and pyridine N centers, and its Co 3+ /Co 2+ ratio. The obtained Co 3 O 4 /NDHCS-0.2/GCE material achieves wide linear ranges from 1.0 to 900 and 1500 to 6500 μM, low limits of detection of 11 nM and 0.516 μM, and high sensitivities (871 and 103 μA mM −1 cm −2 ). The proposed sensor was also employed to test the practical application of the real samples. The dopamine sensor has also shown long-term stability and acceptable reproducibility.

“…Regardless of the difference in electrodes, the MIECs can be divided into two groups according to different preparation methods of MIPs, which are (i) MIPs generated by an in-situ method such as electropolymerization of the monomer and (ii) the preformed MIPs will be coated on the electrode, also named as an ex-situ method [ 38 , 39 ]. For the in-situ method, MIPs can be directly obtained by electropolymerization without any processing requirement.…”

Towards Development of Molecularly Imprinted Electrochemical Sensors for Food and Drug Safety: Progress and Trends

Due to their advantages of good flexibility, low cost, simple operations, and small equipment size, electrochemical sensors have been commonly employed in food safety. However, when they are applied to detect various food or drug samples, their stability and specificity can be greatly influenced by the complex matrix. By combining electrochemical sensors with molecular imprinting techniques (MIT), they will be endowed with new functions of specific recognition and separation, which make them powerful tools in analytical fields. MIT-based electrochemical sensors (MIECs) require preparing or modifying molecularly imprinted polymers (MIPs) on the electrode surface. In this review, we explored different MIECs regarding the design, working principle and functions. Additionally, the applications of MIECs in food and drug safety were discussed, as well as the challenges and prospects for developing new electrochemical methods. The strengths and weaknesses of MIECs including low stability and electrode fouling are discussed to indicate the research direction for future electrochemical sensors.
