A novel green hydrophilic levofloxacin imprinted polymer was presented via one-step polymerization in water using ionic liquid 1,6-hexa-3,3'-bis-1-vinylimidazolium bromine with multiple hydrophilic groups and 2-hydroxyethyl methacrylate as a co-functional monomer. Adsorption experiment revealed that the ionic liquid significantly improved the water compatible of imprinted polymer, and the excellent recognition of molecularly imprinted polymer for levofloxacin in water corresponds to the synergetic effect of H-bonding and the electrostatic and π-π interactions between the levofloxacin and co-functional monomer. Furthermore, the adsorption process of the imprinted material towards levofloxacin fitted the Langmuir model, and the maximum binding amount of levofloxacin onto the imprinted and corresponding non-imprinted polymer were 16.45 and 6.82 mg/g at 25°C, respectively. After optimizing the parameters affecting solid phase extraction performance, an enrichment and determination system was achieved to separate and detect levofloxacin from water and sediment samples with recoveries that ranged from 83.67 to 101.33% and relative standard deviation of less than 5.59%.

An ultrasensitive and selective voltammetric platform combined a molecularly imprinted poly(pyrrole) membrane with Ag-nanoparticle-functionalized black phosphorus nanosheets (MIP/BPNS-AgNPs) was developed for trace GAT detection. The physicochemical properties of the MIP/BPNS-AgNPs were studied by various spectroscopic and electrochemical techniques. BPNS-AgNPs improved the ambient stability and electrochemical activity of the BPNS and possessed a large surface area for accommodating abundant templates to produce specific imprinted sites.

In this study, a mimetic fluorescence nanosensor based on a molecularly imprinted polymer was designed for the detection of amygdalin (AMG). Its characteristics and functional performance were investigated and recorded using ATR-FTIR, AFM and porosity tests. This designed sensor is considered superior to other reported techniques due to its low material consumption during both manufacturing and operation as well as its low cost and desirable performance characteristics, such as short response time, high stability and an appropriate detection limit.

Conventional carbon dots (CDs) typically exhibit substantial variations in fluorescence intensity across different pH. This limitation underscores the pressing need for advancements in their stability and performance under diverse environmental conditions. Herein, l-cysteine and neutral red are selected as precursors, and three kinds of CDs, which can emit red, orange, and green fluorescent light (assigned as r-CD, o-CD, g-CD, respectively), are synthesized by simply changing the reaction conditions.

The large-scale production of glycyrrhizic acid inevitably generates a large amount of licorice residues waste, which contains a wealth of active ingredients, especially glabridin, a natural preservative. However, traditional extraction methods for glabridin are often limited by bottlenecks such as time-consuming, inefficient, and insufficient specificity. To overcome these challenges, this study innovatively introduced 2-phenylimidazole as a functional monomer by computer simulations and successfully developed magnetic molecularly imprinted polymers (MMIPs) for glabridin.

Glycolysis provides tumors with abundant nutrients through glucose (Glu) metabolism. As a therapeutic target, precise targeting and effective inhibition of the glycolysis process remains a major challenge in anti-metabolic therapy. In this study, a novel dual-template molecularly imprinted polymer (D-MIP), capable of specifically recognizing glucose transporter member 1 (GLUT1) and hexokinase-2 (HK2) was prepared for anti-glycolytic tumor therapy.
