“…Without acetamiprid, AuNP-conjugated antigen can combine with UCNP-conjugated mAb, quenching the fluorescence. The fluorescence recovery was observed after acetamiprid inhibited the combination of antigen-AuNPs and UCNPs through the interaction between antibodies and acetamiprid ( Figure 4 d) [ 41 ].…”

“…As acetamiprid triggers the aggregation of AuNPs, thus inhibiting their fluorescence quenching activity, the concentration of acetamiprid can be determined by the photoluminescence intensity of QDs with a LOD of 16.8 μg/L using IFE. In addition, Wang et al [ 41 ] increased the specificity of the detection of acetamiprid by introducing monoclonal antibodies. In this method, by using AuNPs-coupled antigen as a fluorescence closing reagent and UCNPs-coupled monoclonal antibody as a fluorescent light source, the LOD towards acetamiprid was as low as 0.04 μg/L and it showed no cross-reactivity with other pesticides.…”

The excessive and unreasonable use of pesticides has adversely affected the environment and human health. The soil, one of the most critical natural resources supporting human survival and development, accumulates large amounts of pesticide residues. Compared to traditional spectrophotometry analytical methods, nanoparticle-based sensors stand out for their simplicity of operation as well as their high sensitivity and low detection limits. In this review, we focus primarily on the functions that various nanoparticles have and how they can be used to detect various pesticide residues in soil. A detailed discussion was conducted on the properties of nanoparticles, including their color changeability, Raman enhancement, fluorescence enhancement and quenching, and catalysis. We have also systematically reviewed the methodology for detecting insecticides, herbicides, and fungicides in soil by using nanoparticles.

“…However, these methods are time-consuming, tedious, and require expensive instruments and professional operators, which makes them unsuitable for on-site detection. Hence, more innovative and reliable sensing methods including electrochemical method, 7 fluorescence method, 8 immunoassay, 9 and colorimetric method 10 have been developed, which greatly reduce the dependence on large instruments through assistant equipment is still needed. Among them, the colorimetric method has great potential in the rapid detection of pesticide residues due to its unique characteristics such as simple operation, cost-effectiveness, fast response, and so on.…”

“…However, many studies have proved that ACP can harm other non-target organisms including invertebrates and vertebrates, especially pollinators. 6 In general, the excessive and uncontrolled use of neonicotinoids represents a risk to the entire ecosystem due to their high polarity, solubility, and photostability. For this reason, the European Union has placed five neonicotinoid insecticides, including ACP, on the Watch List, i.e., the list of potentially hazardous pollutants.…”

Acetamiprid (ACP) is a systemic insecticide widely used as a replacement for organophosphorus compounds to control sucking-type insects on leafy vegetables, fruits, and tea trees. In this work, bulk polymerized molecularly imprinted polymer was developed using ACP as template, 4-Vinyl pyridine as monomer and ethylene glycol dimethyl acrylate (EGDMA) as cross-linker in the presence of acetone as porogen. After evaluation of five polymeric ratios according to their equilibrium rebinding assay, the MIP comprising 1:3:50 (template: monomer: cross-linker) was found to show the best binding capacity, and thus was chosen as a template recognition for carbon paste electrode in cooperation with multiwalled carbon nanotubes as a signal enhancer. The developed electrode was morphologically and electrochemically characterized and was found to show a linear response for differential pulse voltammetry of 1 × 10-12 – 5 × 10-6 M equivalent to 0.222 – 111.3 ×104 ng/L with limits of detection and quantification of 7.35 × 10-3 and 0.022 ng/L, respectively. The electrode was efficiently applied for ACP detection in its pure solutions, commercial insecticide and spiked apple, tomato, and watermelon samples with recoveries from 95.55 -101.66% indicating its efficiency for application in regulatory units for hazardous food contaminants.
