“…As shown in Figure 3 a, the Bi-MIPs, Bi-NIPs, Si-MIPs and Si-NIPs display a stretching vibration peak of -CH 2 - occurring at 2987 cm −1 , indicating that MAA is contained in polymerization. The stretching vibration peak of the -NH- double bond appeared at 1456 cm −1 , the single-bond vibration region of -CH appeared at 1398 cm −1 , and the stretching vibration peak of -C=O occurred at 1732 cm −1 [ 42 , 43 , 44 , 45 ]. The carbonyl groups tend to have a higher vibration absorption, indicating the successful preparation of the Bi-MIPs, Bi-NIPs, Si-MIPs and Si-NIPs.…”

Chrysin is a natural bioactive molecule with various groups, and it has been a challenge to separate and enrich chrysin from natural products. Molecularly imprinted polymers have been widely used in the extraction of natural products, but the number and type of functional monomers limits the separation effect. The synergistic action of multiple functional monomers can improve the separation effect. In this paper, molecularly imprinted polymers (Bi-MIPs) were prepared using methacrylic acid and acrylamide as binary functional monomers for the separation and enrichment of chrysin. The Bi-MIPs were characterized using thermogravimetric analyzer (TGA), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscope (SEM). The performances of Bi-MIPs were assessed, which included adsorption isotherms, selective recognition and adsorption kinetics. The experimental results show that Bi-MIPs are shaped as a uniform sphere with an abundant pocket structure on its surface. The adsorption of chrysin on the Bi-MIPs followed a pseudo-second-order and adapted Langmuir–Freundlich isotherm models. The adsorption performance of the Bi-MIPs was determined at different temperatures, and the Bi-MIPs showed excellent adsorption performance at 30 °C. The initial decomposition temperature of the Bi-MIPs was 220 °C. After five times of adsorption and desorption, the adsorption performance of the Bi-MIPs decreased by only 7%. In contrast with single functional monomer molecularly imprinted polymers (Si-MIPs), the Bi-MIPs showed excellent specificity, with an imprinting factor of 1.54. The Bi-MIPs are promising materials in the separation and enrichment of chrysin for their high adsorption capacity, low cost and being environmentally friendly.

“…Molecular imprinting is a cost-effective method applying the copolymerization of functional monomers with desired template molecules to create custom-made recognition materials [18,19]. The primary concept is to generate recognition sites within the polymeric matrix for the target analyte, forming speci c recognition cavities upon template removal [20]. Synthetic polymers with these recognition sites exhibit high selectivity for rebinding target molecules and similar structures [21].…”

Saffron is an expensive spice. One of its effective ingredients is crocin, which directly affects the quality and commercial value of saffron. Herein, a simple method has been developed based on magnetic molecularly imprinted polymers (MMIPs) for sensitive and selective extraction of crocin from saffron. MMIPs were prepared using gentiobiose as the template molecule, methacrylic acid as the functional monomer, ethylene glycol dimethacrylate as the cross-linking agent, and Fe3O4@SiO2 as the magnetic support. Nanoparticle characterizations were performed using various techniques, including Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), vibrating sample magnetometry (VSM), and thermogravimetric analysis (TGA). This study investigates different parameters affecting extraction efficiency, isothermal absorption experiments, kinetics absorption experiments, and the selectivity of MMIPs. The analytes were determined by UV-Vis spectrometry and high-performance liquid chromatography (HPLC). The result showed that the sorption of crocin is described by the pseudo-second-order model, and the adsorption equilibrium data fit with the Freundlich model. Also, the sorbent had a homogeneous structure, and that the crocin sorption occurred through multilayer reversible sorption. Under the optimized conditions, the limit of detection and quantification obtained were 0.014 and 0.10 mg L− 1, respectively. The practical utility of the proposed method was evaluated via the extraction of crocin from real samples, with satisfactory results.
