Summary: This work presents a molecularly imprinted (MIP) sensor for the determination of ethanethiol. The MIP/GCE sensor showed a linear range of 6.1-32.4 mg L-1 with good detection capability and reproducibility. The sensitivity of the sensor was enhanced by incorporating gold nano-particles. The sensor was successfully applied to determine ethanethiol in spiked wine samples.

Summary: Molecularly imprinted wax (MIW) spheres were successfully prepared using octadecanoic acid as the functional monomer and wax as the matrix. The MIW spheres displayed remarkable molecular recognition ability and high selectivity towards the template. The as-synthesized MIW could be dissolved in n-hexane or melted by heating for subsequent fluorescence and mass spectrum analysis without the target elution process.

Summary: Selective and sensitive determination of Leptin was achieved using a hybrid sensor with dual recognition elements of aptamers and molecularly imprinted polymers (MIPs). The sensor exhibited a linear response in the concentration range of 1.0 fg/mL to 10.0 pg/mL with a limit of detection (LOD) of 0.31 fg/mL. Real samples, including human serum and plasma, were successfully analyzed with satisfactory recovery findings (106.2-109.0%).

Summary: Electrochemical sensors are increasingly important in medicine, environmental monitoring, and industrial process control. However, their development faces challenges such as low target compound concentrations and complex analytical matrices. Mesoporous Thin Films (MTFs) have attracted great interest as electrode modifications due to their high surface area, uniform pore distribution, and electrochemical signal modulation possibilities. To fully exploit the advantages of MTFs, reproducible methods for sensitive and selective MTF-modified electrodes need to be developed, and mass and charge transport processes within the film and on the electrode need to be understood.

Summary: A novel electrochemical sensor based on a screen-printed graphene paste electrode modified with platinum nanoparticles and coated with a molecularly imprinted polymer was proposed for sensitive and cost-effective detection of paraquat herbicide. The sensor showed high sensitivity, selectivity, and a lower detection limit for quantification of paraquat residue on vegetables and fruits. The ready-to-use MIP sensor offers an alternative approach for food safety applications.
