“…The speci c recognition performance of MIPs@SiO 2 @CdTe for NOR can accurately detect the linear concentration range of NOR from 3.82 nmol/L to 150 nmol/L, and the detection limit of NOR is 3.82 nmol/L, which has been successfully applied to the detection and analysis of actual samples. Chen et al (Chen et al 2021) developed a new probe for rapid detection of NOR residues in food substrates. Using magnetic roomtemperature phosphorescent quantum dots and MIPs (MQD-MIPs) as raw materials, the detection limit of this new probe can reach 0.80 µg/L.…”

Fluoroquinolones are a new class of synthetic antimicrobials, which have been widely used in clinical treatment. However, their irrational use can lead to allergic reactions, adverse reactions of the heart system and damage of the liver system. Due to the urgency of the safety risk of fluoroquinolones, it is of great significance to establish rapid, sensitive and accurate detection methods for fluoroquinolones. Molecularly imprinted polymers with specific structures synthesized by molecular imprinting technology are widely used for the detection of fluoroquinolones due to their high specificity, high sensitivity and stable performance. Besides, new functional nanomaterials with different morphology and size can provide rich sites for surface chemical reactions, thus greatly promoting the sensitivity and innovation of molecular imprinted polymer. This review summarizes the application status and development prospects of molecular imprinting technology based on novel nanomaterials labeling in the adsorption and detection of fluoroquinolones, in order to provide references for the future research on the adsorption and removal of fluoroquinolones, analysis and detection fluoroquinolones.

“…This will achieve better recognition efficiency. Chen et al developed a novel room-temperature phosphorescence MNPs@QDs-MIPs probe for tracing norfloxacin residue in milk and fish [160]. The MNPs@QDs-MIPs realized a highly specific fluorescence response to norfloxacin, and linearity ranged from 1 to 90 µg/mL with a LOD of 0.8 µg/mL.…”

The presence of food contaminants can cause foodborne illnesses, posing a severe threat to human health. Therefore, a rapid, sensitive, and convenient method for monitoring food contaminants is eagerly needed. The complex matrix interferences of food samples and poor performance of existing sensing probes bring significant challenges to improving detection performances. Nanocomposites with multifunctional features provide a solution to these problems. The combination of the superior characteristics of magnetic nanoparticles (MNPs) and quantum dots (QDs) to fabricate magnetic fluorescent quantum dots (MNPs@QDs) nanocomposites are regarded as an ideal multifunctional probe for food contaminants analysis. The high-efficiency pretreatment and rapid fluorescence detection are concurrently integrated into one sensing platform using MNPs@QDs nanocomposites. In this review, the contemporary synthetic strategies to fabricate MNPs@QDs, including hetero-crystalline growth, template embedding, layer-by-layer assembly, microemulsion technique, and one-pot method, are described in detail, and their advantages and limitations are discussed. The recent advances of MNPs@QDs nanocomposites in detecting metal ions, foodborne pathogens, toxins, pesticides, antibiotics, and illegal additives are comprehensively introduced from the perspectives of modes and detection performances. The review ends with current challenges and opportunities in practical applications and prospects in food contaminants analysis, aiming to promote the enthusiasm for multifunctional sensing platform research.
