Showed decreased specificity. A carbon dot functionalized fluorescent MIP was fabricated for the detection of dinitrotoluene in groundwater with AA because the functional monomer, EDGMA, and AIBN [247]. The sensor was tested in spiked lake water and tap water samples, with all round 1-Oleoyl-2-palmitoyl-sn-glycero-3-PC site acceptable efficiency,Molecules 2021, 26,19 ofalthough organic matter interfered together with the fluorescence signal. This drawback was partially overcome by a non-labeled photonic MIP sensor, with all the optical active structure obtained by conducting the polymerization in the pore space of a sacrificial colloidal crystal: the system permitted the detection of 2-butoxyethanol wastewater from hydraulic fracking operations. The sensor performed well, but the polyacrylic acid polymer was severely damaged by the wastewater soon after every single use and could not be recycled [220]. Bisphenol A (BPA) is another chemical of concern that was the target of a number of MIP-sensors. A fluorescence MIP sensor was fabricated combining silica-coated fluorescent carbon dots through sol-gel polymerization to become used in river water samples [239]. Xue et al. [279] fabricated surface-imprinted core-shell Au nanoparticles of BPA for detection by SERS in surface water and plastic bottled beverages. Both sensors showed fantastic functionality in laboratory prepared normal solutions, and acceptable measurements within a handful of true samples, despite the fact that low pH beverages resulted in incredibly low recoveries. A photonic sensor was proposed by Kadhem at al. [221] for the detection of testosterone in organic water, one more instance of endocrine disrupting chemical compounds in the atmosphere. A mixture of AA, EDGMA, AIBN, along with the target was polymerized inside a silica particles crystal that offered the optically active morphology. Rebinding with the target developed swelling on the polymer and consequent change inside the wavelength from the reflected light. The sensor showed minimal non-specific adsorption and great reusability in laboratory-made test samples. Quite a few optical TG6-129 Prostaglandin Receptor MIP-based sensors have already been reported for the detection of pesticides and veterinary antibiotics. Zhao et al. [212] fabricated a MIP for atrazine extraction from apple juice by bulk polymerization of MAA, EGDMA, chloroform, and AIBN, reacted in an oil bath at 60 C for 24 h. The obtained monolith was ground and sieved, the template removed by Soxhlet extraction, and particles were packed into a solid-phase-extraction cartridge. The pretreated option was analyzed by a colorimetric system determined by Au nanoparticles for rapid detection by SERS, nevertheless it didn’t attain a low LOD nor a linearity within the response. A sensor for the herbicide 2,4-dichlorophenoxyacetic acid was developed by Wagner et al. [231] employing fluorescent core-shell MIP particles in a 3-dimensional microfluidic method for droplet extraction from the water matrix and mixture using the MIP, that reached a LOD under the drinking water guideline. However, nonspecific binding as a consequence of matrix effects have been observed. Electrochemiluminescent graphene quantum dots have been proposed for the detection of the herbicide 2-methyl-4-chlorophenoxyacetic acid [254]. A layer of hybrid nanocomposite of graphene quantum dots and MoS2 , within a mass ratio of 2:3, was coated on a GCE upon which the MIP was synthetized by cyclic voltammetry with 2methyl-4-chlorophenoxyacetic acid as the selected template and also the functional monomer o-PD. The template removal was achieved by shaking in methanol and acetic acid. Samples have been subjected to an extensive.
