“…The use of electrospun SnO 2 for detection of atrazine enabled LOD of 0.9 zM [ 82 ]. Lately, several sensors for determination of methyl parathion were also reported, but with typical LODs for electrochemical detection in the submicro to the nanomolar range: 3D flower-like praseodymium molybdate-decorated reduced graphene oxide (LOD 1.8 × 10 −3 μM), MnO 2 /PANI/rGO-A (LOD 7.4 × 10 −3 μM) [ 85 ] and a monolayer of zirconium (IV) phosphonate on glassy carbon electrode (LOD 0.0045 μM) [ 86 ]. Also, the chitosan/magnetic Fe 3 O 4 nanocomposite-modified glassy carbon electrode in combination with square wave voltammetry was used for bendiocarb determination, but the LOD was 2.09 μM with a LOQ of 6.97 μM [ 87 ].…”

Electrochemical sensors play a significant role in detecting chemical ions, molecules, and pathogens in water and other applications. These sensors are sensitive, portable, fast, inexpensive, and suitable for online and in-situ measurements compared to other methods. They can provide the detection for any compound that can undergo certain transformations within a potential window. It enables applications in multiple ion detection, mainly since these sensors are primarily non-specific. In this paper, we provide a survey of electrochemical sensors for the detection of water contaminants, i.e., pesticides, nitrate, nitrite, phosphorus, water hardeners, disinfectant, and other emergent contaminants (phenol, estrogen, gallic acid etc.). We focus on the influence of surface modification of the working electrodes by carbon nanomaterials, metallic nanostructures, imprinted polymers and evaluate the corresponding sensing performance. Especially for pesticides, which are challenging and need special care, we highlight biosensors, such as enzymatic sensors, immunobiosensor, aptasensors, and biomimetic sensors. We discuss the sensors’ overall performance, especially concerning real-sample performance and the capability for actual field application.

“…But frequent pesticide applications could contaminate the environment and enter the food chain, leading to acute or chronic poisoning. , Therefore, it is very important to find cheap, fast, highly selective, and sensitive detection methods to monitor these substances for tracking pesticide residues in the environment. Many well-established methods have been widely reported for detecting MP residues, such as electrochemical, − fluorescence, − gas chromatography (GC), − spectrophotometry, − and immunoassay. − Although the aforementioned methods have outstanding sensitivity and accuracy, their use is still constrained by some inherent limitations, such as complicated preprocessing, high cost, and operational proficiency, which prevents their use in real-time situations.…”

Real-time/field sensing techniques to keep track of methyl parathion (MP) are crucial to human health. In this work, a ratiometric fluorescence probe was constructed by integrating green carbon dots and CdTe quantum dots (CdTe QDs) for highly selective quantitative detection of MP. Under alkaline conditions, MP can be rapidly hydrolyzed to produce pnitrophenol (p-NP); the instantaneous reaction that strengthens the hydrogen bond results in the internal filter effect between the carbon dots and p-NP, which quenches green fluorescence, thus leading to an obvious and immediate change from green to red. The probe displayed a sensitive limit of detection of 8.9 nM and exhibited a significant linear response to MP residue concentrations in the range of 0−100 M. In addition, we have created a brand-new smartphone-based intelligent detection tool by measuring the RGB value of the fluorescent probe solution and the matching paper-based sensor, and we are able to visually and quantitatively identify the levels of MP residues present in water, apples, and vegetables. This ratiometric fluorescence sensing method can realize rapid visual and quantitative detection of MP residues, which provides a more reliable guarantee promising strategy for constructing a risk detection technique for traces without enzymes.

Inorganic nanomaterials have gained significant attention as an efficient electrocatalyst for several electrochemical applications in the past few years. Here, we demonstrate the preparation of hexagonal nanoplate-like zirconium phosphate (ZrP) through a facile hydrothermal technique and its application for the electrochemical detection of furazolidone (FZD). Several characteristic measurements are systematically carried out to confirm the formation of pure-phase ZrP. The hexagonal nanoplate-like ZrP catalyst exhibits excellent electrochemical activities toward FZD detection owing to its highly active centers exposed on the surfaces and site populations. The ZrP-based sensor possesses a low limit of detection (1.2 nM), wide working range (0.009–339 μM), high sensitivity (1.312 μA/(μM cm2)), rapid response (<3 s), excellent stability, and good anti-interference ability toward FZD sensing. Furthermore, the proposed electrochemical sensor is considered competitive compared to the previously reported sensors. Besides, the practicability of the produced electrochemical sensor was successfully applied to accurately detect FZD in food samples. The synthesized nanomaterial delivers a pathway toward the rational construction of electrocatalysts for diverse electrochemical technologies.
