“…The absorption peak at 1104 cm −1 corresponds to the antisymmetric stretching vibration of the Si-O-Si bonds [ 30 ]. The peak at 582 cm −1 corresponds to the absorption peak of the Fe-O bond in the magnet [ 31 ]. The peak at 1632 cm −1 corresponds to the carbon–carbon double bond (C=C) and the skeleton vibration of the benzene ring [ 32 ].…”

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.

“…Additionally, 2 mL phosphate buffer solution (PBS, 0.01 M, pH 7.4) was added to the precipitates and mixed thoroughly. Then, anti−OLA−mAb (10,20,40, and 60 μg/mL) was added and incubated at room temperature for 2 h. For inhibiting the nonspecific locus, 500 μL 1% BSA (w/v) was added to the aforementioned solution. The diluent of BSA was PBS (0.01 M, pH 7.4).…”

Olaquindox (OLA) and quinocetone (QCT) have been prohibited in aquatic products due to their significant toxicity and side effects. In this study, rapid and visual europium nanoparticle (EuNP)−based lateral flow strip biosensors (LFSBs) were developed for the simultaneous quantitative detection of OLA, QCT, and 3−methyl−quinoxaline−2−carboxylic acid (MQCA) in fish feed and tissue. The EuNP−LFSBs enabled sensitive detection for OLA, QCT, and MQCA with a limit of detection of 0.067, 0.017, and 0.099 ng/mL (R2 ≥ 0.9776) within 10 min. The average recovery of the EuNP−LFSBs was 95.13%, and relative standard deviations were below 9.38%. The method was verified by high−performance liquid chromatography (HPLC), and the test results were consistent. Therefore, the proposed LFSBs serve as a powerful tool to monitor quinoxalines in fish feeds and their residues in fish tissues.

“…Compared with the traditional solid phase extraction method, MSPE can effectively solve or alleviate the problems of long extraction time, poor trace extraction effect, and weak anti-interference ability. In a previous study, Professor Tang 21 synthesized a core–shell magnetic molecular imprinting polymer (MMIP) Fe 3 O 4 @SiO 2 @MIPs for enrichment of olaquindox and its metabolic marker. Based on this material, a magnetic solid phase extraction HPLC method was developed.…”
