“…Despite the inherent lower sensitivity of linear sweep voltammetry (LSV) vs. DPV or SWV some authors report the use of LSV coupled to MIP sensors. Xie et al [ 152 ] and Zhang et al [ 153 ] proposed two MIP sensors exploiting the LSV for the detection of pesticides in brown rice. The MIPs were obtained by free-radical polymerization of p -vinylbenzoic acid (VBA) on the surface of a GCE modified with graphene (GN).…”

“…Xie et al [ 152 ] reported a facile synthesis of a MIP sensor for detection of thiamethoxam residue; the detection limit was 4.00 × 10 −8 M and the recovery range was 88.7–94.0%. Zhang et al [ 153 ] proposed a sensor for the determination of imidacloprid (IMI) residue. The detection limit was 1.00 × 10 −7 M and the method gave acceptable recoveries from 75.0% to 78.0%.…”

This is a review of recent affinity-based approaches that detect pesticides in food. The importance of the quantification and monitoring of pesticides is firstly discussed, followed by a description of the different approaches reported in the literature. The different sensing approaches are reported according to the different recognition element used: antibodies, aptamers, or molecularly imprinted polymers. Schemes of detection and the main features of the assays are reported and commented upon. The large number of affinity sensors recently developed and tested on real samples demonstrate that this approach is ready to be validated to monitor the amount of pesticides used in food commodities.

“…Electrochemical sensors have emerged in recent years as alternatives for pesticides detection, with benefits related to the low cost, simplicity, high sensitivity and waste reduction, among others 16,17 . The redox properties of IMD and other pesticides allow their detection through electrochemical measurements [18][19][20] .…”

“…MIPs' excellent high thermal and chemical stability and selectivity made them a promising alternative to natural bioreceptors for analysis in complex matrices. MIPs have been widely used in chromatography 10 , solid-phase extraction (SPE) 16 , drug delivery 17 , water treatment 18 , membrane separations 19 , and chemical sensors 20,21 . MIPs have been used as receptors in many electrochemical platforms.…”

“…Nearly all the previously synthesized MIPs toward IMD were primarily used for SPE and focused mainly on foodstuffs 10,16,27,28 . However, there are a few reports on the application of MIPs in electrochemical sensing for IMD detection in vegetables 20,29 , fruits 29,30 , rice 31 , celery juice 32 and water samples 33 . However, those sensors show a low limit of detection, and removal of the template after polymerisation is a general drawback for in-situ-synthesized MIPs-based sensors 34 .…”

this manuscript reports on the development of a capacitive sensor for the detection of imidacloprid (IMD) in water samples based on molecularly imprinted polymers (MIPs). MIPs used as recognition elements were synthesized via a photo-initiated emulsion polymerization. The particles were carefully washed using a methanol (MeOH) /acetic acid mixture to ensure complete template removal and were then dried. The average size of the obtained particles was less than 1 µm. The imprinting factor (IF) for IMD was 6 and the selectivity factor (α) for acetamiprid, clothianidin, thiacloprid and thiamethoxam were 14.8, 6.8, 7.1 and 8.2, respectively. The particles were immobilized on the surface of a gold electrode by electropolymerization. The immobilized electrode could be spontaneously regenerated using a mixture of MeOH/10 mM of phosphate buffer (pH = 7.2)/triethylamine before each measurement and could be reused for 32 times. This is the first-time that automated regeneration was introduced as part of a sensing platform for IMD detection. The developed sensor was validated by the analysis of artificially spiked water samples. Under the optimal conditions, the linearity was in the range of 5-100 µM, with a limit of detection (LOD) of 4.61 µM. Nowadays, neonicotinoids (neonics) are the most important class of pesticides in the global market. Their "success" story started in 1991 by introducing imidacloprid (IMD) on the market. Since then, for many years IMD has become the world's largest selling pesticide with the registered uses for over 140 crops in 120 countries 1,2. It is extensively used at a large scale with applications ranging from plant protection, veterinary products, and seed coating. As a result of its extensive usage, IMD can be found as a pollutant in all environmental compartments (soil, water and air) 3. Neonics act by binding to the nicotinic acetylcholine receptors (nAChRs) in their target invertebrates. They mimic the action of neurotransmitters, leading to the continuous stimulation of neurons. In doing so, they could cause the death of their target invertebrates 3. Neonics are highly water soluble, persistent in water, soil, minimally degraded by light and not volatile, which make them easily transported from an area of application to different environmental compartments 4. In addition to that, it was found that like other pesticides they have a negative impact on non-target organisms. IMD and other members of the first generation are highly toxic to bees 5,6. These chemical properties in addition to their negative environmental impacts have raised EU concern 7. Pesticides in general could easily contaminate supplies of drinking water via surface or ground water systems. Depending on the quantity and toxicity level of a pesticide together with the frequency of exposure to the contaminated drinking water, pesticides in water could negatively affect human health and environment. It was found that neonics could have lethal and sublethal effects on many aquatic invertebrates. The acute and chronic neonics t...
