“…Gold (Au), silver (Ag), silica (SiO2), QDs, and iron oxide (Fe3O4) nanoparticles have been extensively used as core materials to support the surface imprinting Decades of research have demonstrated the superior performance of micro-and nanosized MIPs compared to their bulk macroscopic counterparts [29][30][31]. MIPs can be fabricated in various formats such as films [32], membranes [33], hydrogels [34], microparticles [35], multi-walled carbon nanotubes (MWCNTs) [36], or nanoparticles [37]. The overall performance of large and macroscopic bulk materials-based MIPs is compromised due to the heterogeneity of their analyte binding site and the poor accessibility of interior binding sites.…”

Molecularly imprinted polymers (MIPs) continue to gain increasing attention as functional materials due to their unique characteristics such as higher stability, simple preparation, robustness, better binding capacity, and low cost. In particular, MIP-coated inorganic nanoparticles have emerged as a promising platform for various biomedical applications ranging from drug delivery to bioimaging. The integration of MIPs with inorganic nanomaterials such as silica (SiO2), iron oxide (Fe3O4), gold (Au), silver (Ag), and quantum dots (QDs) combines several attributes from both components to yield highly multifunctional materials. These materials with a multicomponent hierarchical structure composed of an inorganic core and an imprinted polymer shell exhibit enhanced properties and new functionalities. This review aims to provide a general overview of key recent advances in the fabrication of MIPs-coated inorganic nanoparticles and highlight their biomedical applications, including drug delivery, biosensor, bioimaging, and bioseparation.

When consumed in excessive amounts, histamine (HIS), a naturally occurring component in seafood, is known to produce an unpleasant inflammatory reaction. Hence, proper histamine measurement and detection in seafood are of utmost importance. Herein, a histamine electrochemical biosensor based on a molecularly imprinted polymer (MIP) was fabricated using a gold (Au) inverse opal (IO) electrode. Prior to the MIP synthesis, the scaffold of Au IO was modified by electropolymerizing 3,4-ethylenedioxythiophene (EDOT), providing a substrate with improved electrical characteristics. The fabrication of the MIP film was achieved by electropolymerizing aniline in circumstances that preserved the chemical structure of HIS. The electron transport properties of a standard redox probe [Fe(CN) 6 ] 3−/4− were evaluated by making use of cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). We describe a synergistic strategy for constructing a hierarchical recognition material using an electrochemical approach that successfully integrates three independent approaches, including semicovalent, molecular imprinting, and inverse opal structure, to enhance selectivity and sensitivity. The fabricated HIS electrochemical biosensor exhibited a linear response from 50 nM to 500 μM, a detection limit of 1.07 nM, and was selective against different analytes as well. Moreover, the fabricated HIS electrochemical biosensor outperforms its contemporary counterparts as it also exhibited low error, high accuracy, specificity, stability, and good relative standard deviation % (RSD %).

“…15,16 The MIPCH sensor structure has recognition cavities that bind specifically to imprinted molecules in the mixture, enabling recognition and detection of the target. 17 At present, MIPCH with high sensitivity and convenient detection has been successfully used to detect a variety of substances, such as simetryn, 18 L-kynurenine, 19 chlorantraniliprole, 20 2chlorophenol, 21 oxytetracycline 22 and sulfaguanidine. 23 Compared with 3D PCs, the fabrication process of 2D PCs is simple.…”

Using polystyrene two-dimensional photonic crystal as template, gatifloxacin (GTFX) as imprinting molecule, methanol as solvent, acrylic acid as functional monomer, ethylene glycol dimethyl acrylate as crosslinking agent and 2,2diethyloxyacetophenone as initiator, after UV initiation polymerization the GTFX molecularly imprinted two-dimensional photonic crystal hydrogel (GTFX-MIPCH) sensor was prepared. The response performance of the hydrogel was investigated by measuring the diameter change of the Debye ring. The experimental results showed that the prepared GTFX-MIPCH has a sensitive response to GTFX. When the concentration of GTFX increases from 0 to 1 × 10 −4 mol L −1 , the diameter of the Debye ring decreases by 8.50 mm, the corresponding particle spacing increases by 29.1 nm, and the color of the sensor changes from purple to orange. Also there was a linear relationship between the change of particle spacing (Δd) and the logarithm of GTFX concentration (lg c) in the range 10 −12 -10 −6 mol L −1 . It is noteworthy that the limit of detection of GTFX-MIPCH is as low as 10 −14 mol L −1 . In addition, in a solution of GTFX analogues enrofloxacin, levofloxacin, ciprofloxacin and norfloxacin, the change of particle spacing of the GTFX-MIPCH sensor is 13.3, 11.6, 11.1 and 10.3 nm respectively, indicating that GTFX-MIPCH has good specific recognition ability for GTFX. Moreover, GTFX-MIPCH shows good reusability and can also be used for the detection of GTFX in water samples. This GTFX-MIPCH can achieve a visual detection effect on GTFX through the Debye ring and color change.
