“…The adsorption capacity of ZDM-MIPs for ASP was higher than that reported in other literatures. 40,41 The results also indicated the existence of specific recognition sites on the molecularly imprinted layer in ZDM-MIPs, thus resulting in substantial specific adsorption capacity for the template ASP.…”

“…35 For the water-compatible surface imprinting of 'saccharin sodium' on a silica surface for selective recognition and detection in aqueous solution, it has been reported that the saccharin sodium-MIP lost 12-15% of its adsorption capacity on average over ve cycles. 36 The reusability of our MIP-GN/GCE is compared with other reported methods using MIPs, demonstrating high stability and maintaining almost the same adsorption capacity for the template TMX. In addition, the repeatability of MIP-GN/GCE was determined through replicate testing of the response values for different batch electrodes to the same sample (5 mM TMX).…”

aIn this study, we report a facile method for the preparation of molecularly imprinted polymer based graphene for the electrochemical detection of thiamethoxam residue. We choose p-vinylbenzoic acid as a functional monomer; it can be used to add recognition units and alkenyl units onto the surface of graphene via p-p interactions in just one step, effectively simplifying the reaction process. And an ultrathin imprinting film (2 nm) is formed by reducing the addition step involving the alkenyl modifier. Due to the irreversible electrochemical reduction characteristics of thiamethoxam, the template can be removed easily using cyclic voltammetry scanning, without the need for organic solvents. The performance of the fabricated sensor was evaluated and the results indicated that the sensor exhibited excellent specific recognition abilities for thiamethoxam detection; the imprinting factor is 2.36. The peak current from thiamethoxam is linearly proportional to its concentration over the range from 0.5 to 20 mM, and the detection limit is 0.04 mM. The practical application of the sensor was also realized in the selective detection of thiamethoxam in real samples.

“…The loss observed between 90–100 °C in MMIPs is attributed to residual water molecules and other impurities, while the 53% mass loss occurring between 100–200 °C is caused by the thermal cleavage of the functional monomer 3-aminophenylboronic acid and the cross-linking agent N,N′-methylenebisacrylamide. The mass loss observed after reaching 600 °C is mainly due to the loss of bound water in SiO 2 [ 33 ].…”

In this study, a highly efficient magnetic molecularly imprinted polymer nanocomposite material was prepared using multi-walled carbon nanotubes as carriers. The characterization of the obtained nanocomposite material was conducted using Fourier transform infrared spectroscopy, a vibrating sample magnetometer, a thermogravimetric analyzer, a scanning electron microscope, and a transmission electron microscope. The adsorption properties of the nanocomposite material were evaluated through adsorption experiments, including static adsorption, dynamic adsorption, and selective recognition studies. The prepared nanocomposite material, serving as a selective adsorbent, was applied in magnetic solid-phase extraction. Subsequently, the derivatized samples were analyzed for glucose in fish serum using liquid chromatography–tandem mass spectrometry. Under optimal conditions, the detection limit was 0.30 ng/mL, the quantitation limit was 0.99 ng/mL, satisfactory spiked recovery rates were obtained, and the relative standard deviation was less than 1.1%. Using 2-deoxy-D-ribose as the template molecule and a structural analog of glucose allowed us to eliminate the potential template leakage in qualitative and quantitative analyses, effectively avoiding the issues of false positives and potential quantitative errors, compared to traditional methods. A method for detecting glucose levels in fish serum based on molecularly imprinted polymer technology has been successfully developed to determine the stress and health levels of fish.
