Molecularly imprinted membrane of β-caryophyllene (MIM-βCP) was fabricated incorporating β-caryophyllene molecularly imprinted polymer nanoparticles (βCP-NP) into polycaprolactone (PCL) fibers via electrospinning. The βCP-NP were synthesized by precipitation polymerization using the βCP as a template molecule and acrylic acid as a functional monomer in the proportion of 1:4 mol, respectively. Atomic force microscopy images and X-ray diffraction confirmed the nanoparticles' incorporation into MIM-βCP. MIM-βCP functionalization was evaluated by gas chromatography. The binding capacity was 1.80 ± 0.05 μmol/cm, and the selectivity test was performed with a mixing solution of βCP and caryophyllene oxide, as an analog compound, that extracted 77% of the βCP in 5 min. The electrospun MIM-βCP can be used to detect and extract the βCP, applications in the molecular sieve, and biosensor production and may also contribute as an initial methodology to enhance versatile applications in the future, such as in the treatment of skin diseases, filters for extraction, and detection of βCP to prevent counterfeiting of commercial products, and smart clothing with insect-repellent properties.

Surface plasmon resonance (SPR) sensors have emerged as a powerful tool in biosensing applications due to their ability to provide sensitive and real-time detection of chemical and biological analytes. This review focuses on the development and application of molecularly imprinted polymer (MIP)-based SPR sensors for food analysis. By combining the high selectivity of molecular imprinting techniques with the sensitivity of SPR, these sensors offer significant advantages in detecting food contaminants and other target molecules.

A molecularly imprinted fluorescent aptasensor was designed for selective detection of quinine (Qn) based on dual functional monomers. In the sol-gel polymerization of molecularly imprinted polymers (MIPs), 3-aminopropyltriethoxysilane (APTES) and quinine aptamer (Apt) were employed as dual functional monomers, and Qn was the template molecule. Near-infrared carbon dots (RCDs) were used as fluorescence signal probe, and effectively avoided the interference of fluorescence emitted by Qn.

The concentration of chlorpyrifos (CPF) in aqueous samples was determined using a novel molecularly imprinted dispersive solid-phase extraction (MISPE) approach that was presented in this research. Using a non-covalent molecular imprinting technique, a biochar (BC)-functionalized molecularly imprinted polymers (MIPs) (BC-MIPs) was created. These MIPs were used in dispersive solid-phase extraction (DSPE) in conjunction with high-performance liquid chromatography with photodiode array detection (HPLC-PDA) to detect CPF in aqueous samples with high sensitivity.

In this work, magnetic molecularly imprinted polymer (MMIP) capable of selectively recognizing and adsorbing cordycepin was prepared. The MMIP was prepared using cordycepin as the template molecule, methacrylic acid and acrylamide as the functional monomer and ethylene glycol dimethacrylate as the crosslinker. The MMIP was analyzed using various techniques including transmission electron microscopy, thermogravimetric analysis, Fourier transform infrared spectroscopy, vibrating sample magnetometer and x-ray diffraction.
