“…The pirimicarb binding to polymer caused the turn-on fluorescent intensity that is generally related to the transition from π to π* of the C=C bonds and benzene rings or from n to π* of C=O bonds or others, respectively. The fluorescence intensity was increased via π–π interaction, and exhibits stable solid-state photo-luminescence (PL) to monitor the pirimicarb loading and releasing through the Förster resonance energy transfer with the pirimicarb like tramadol and doxorubicin 54 – 56 . The absorbance experiment showed that an interaction exists between pirimicarb and MIP polymer that turns on the absorbance behavior of MIP dependent on pirimicarb 57 .…”

In this study, a sensitive and selective fluorescent chemosensor was developed for the determination of pirimicarb pesticide by adopting the surface molecular imprinting approach. The magnetic molecularly imprinted polymer (MIP) nanocomposite was prepared using pirimicarb as the template molecule, CuFe2O4 nanoparticles, and graphene quantum dots as a fluorophore (MIP-CuFe2O4/GQDs). It was then characterized using X-ray diffraction (XRD) technique, Fourier transforms infrared (FT-IR) spectroscopy, scanning electron microscope (SEM), and transmission electron microscopy (TEM). The response surface methodology (RSM) was also employed to optimize and estimate the effective parameters of pirimicarb adsorption by this polymer. According to the experimental results, the average particle size and imprinting factor (IF) of this polymer are 53.61 nm and 2.48, respectively. Moreover, this polymer has an excellent ability to adsorb pirimicarb with a removal percentage of 99.92 at pH = 7.54, initial pirimicarb concentration = 10.17 mg/L, polymer dosage = 840 mg/L, and contact time = 6.15 min. The detection of pirimicarb was performed by fluorescence spectroscopy at a concentration range of 0–50 mg/L, and a sensitivity of 15.808 a.u/mg and a limit of detection of 1.79 mg/L were obtained. Real samples with RSD less than 2 were measured using this chemosensor. Besides, the proposed chemosensor demonstrated remarkable selectivity by checking some other insecticides with similar and different molecular structures to pirimicarb, such as diazinon, deltamethrin, and chlorpyrifos.

We describe a simple hydrothermal method for preparing a nanocomposite of reduced graphene oxide/Mn3O4 (rGO/Mn3O4), and its use in electrochemically detecting tramadol (TRA). The sensor was constructed by using a glassy carbon electrode modified with a rGO/Mn3O4 nanocomposite (rGO/Mn3O4/GCE) as an electro‐catalyst. The electrochemical properties of TRA at rGO/Mn3O4/GCE were studied using cyclic voltammetry (CV), chronoamperometry, and differential pulse voltammetry (DPV) in a phosphate buffer solution (PBS) with a pH of 8.0. The oxidation peak currents of TRA on rGO/Mn3O4/GCE increased compared to the bare GCE. This enhancement was attributed to the high surface area and excellent electron transfer performance of the rGO/Mn3O4 nanocomposite on the surface of the electrode. Under optimal conditions, the oxidation peak currents exhibited a linear increase with the concentration of TRA within the range of 0.5 to 700.0 μM, and a detection limit (LOD) of 0.16 μM was achieved. This study has shown that the rGO/Mn3O4/GCE can effectively be used to analyze TRA in real specimens.
