Fast sonochemical molecularly imprinted polymer synthesis for selective electrochemical determination of maleic hydrazide

Study on Molecularly Imprinted Polymers Obtained Sonochemically for the Determination of Aflatoxins in Food

“…Different routes have been employed to produce MIPs, exploiting different approaches to promote polymerization, such as thermal heating [ 23 , 24 ], photoinduction, microwave [ 25 ], and sonication in ultrasonic baths [ 26 , 27 ]. In the last few years, researchers have explored the rapid synthesis of MIPs by high-power ultrasound probes, which enables the speeding up of the polymerization process [ 28 , 29 , 30 ]; this strategy has also allowed the production of effective MIPs for analytes in those cases where conventional techniques were not successful. To the best of our knowledge, there are only a few works regarding MIPs for AFs and the proposed strategies are based on long procedures ( Table S1 ).…”

Green Synthesis of Molecularly Imprinted Polymers for Dispersive Magnetic Solid-Phase Extraction of Erythrosine B Associated with Smartphone Detection in Food Samples

“…Recently, molecularly imprinted polymers (MIPs) have attracted considerable attention as promising elements for specific recognition in chemical and biological sensors [ 18 ]. Molecular imprinting is a technique that generates molecular recognition sites that are chemically and sterically complementary to the target molecule [ 18 , 19 , 20 ]. In particular, the surface molecular printing technique combined with magnetic nanomaterials has attracted considerable interest because magnetic MIPs can be easily moved/separated by using an external magnet [ 21 ].…”

“…Recently, dopamine (DA), a biomolecule containing catechol and amine functional groups, has attracted the attention of researchers, particularly for its ability to self-polymerize in an aqueous alkaline or oxidizing solution without crosslinking or initiating agents [ 22 ], allowing the realization of different nanomaterial-based devices, sensing systems [ 23 , 24 , 25 , 26 ], and MIPs [ 27 , 28 ]. In addition to their use for sample extractions, the other major contribution that has led to improvements in the quantitative application of MIPs regards their combination with non-chromatographic techniques as UV–visible spectroscopy [ 19 ], Raman, fluorescence spectroscopy, and electrochemical techniques [ 20 ]. Considering the intense color provided by ERT-B in the visible spectrum, it is clearly expected that cost-effective and sensitive measurements with smartphone-based camera technology should lead to successful detection.…”
