“…Pellicer et al reported on MIPs using Ni (II)-phtalocyanine, a known surface modifier with excellent conducting properties, for the voltammetric detection of the pesticide, fenitrothion [ 103 ]. A highly selective sensor for the veterinary drug, oxfendazole, was developed by the direct electrodeposition of pyrrole onto SPEs [ 104 ]. The sensitivity of the MIP-modified SPE sensors can be enhanced by including fillers, such as conductive polymers, graphene, and AuNPs [ 105 ].…”

The accurate detection of biological materials has remained at the forefront of scientific research for decades. This includes the detection of molecules, proteins, and bacteria. Biomimetic sensors look to replicate the sensitive and selective mechanisms that are found in biological systems and incorporate these properties into functional sensing platforms. Molecularly imprinted polymers (MIPs) are synthetic receptors that can form high affinity binding sites complementary to the specific analyte of interest. They utilise the shape, size, and functionality to produce sensitive and selective recognition of target analytes. One route of synthesizing MIPs is through electropolymerization, utilising predominantly constant potential methods or cyclic voltammetry. This methodology allows for the formation of a polymer directly onto the surface of a transducer. The thickness, morphology, and topography of the films can be manipulated specifically for each template. Recently, numerous reviews have been published in the production and sensing applications of MIPs; however, there are few reports on the use of electrosynthesized MIPs (eMIPs). The number of publications and citations utilising eMIPs is increasing each year, with a review produced on the topic in 2012. This review will primarily focus on advancements from 2012 in the use of eMIPs in sensing platforms for the detection of biologically relevant materials, including the development of increased polymer layer dimensions for whole bacteria detection and the use of mixed monomer compositions to increase selectivity toward analytes.

“…On the other hand, UV spectrophotometry [12] and non-aqueous titrimetry [13] respectively, for small and large amounts of these drugs are methods that eventually fail by lack of the suitable accuracy, precision, sensibility and selectivity. In turn, the electroanalytical methods, are recognized by their great sensitivity, modular selectivity, creativity due to no need for pre-treatment or preseparation, reduced cost for acquisition and/or maintenance of equipment and accessories and eco friendly low consume of reagents [8,9,14].…”

“…The sensors can selectively recognize the template molecule with specificity based on the cavities in the spatial structure and binding sites in molecularly imprinted polymer membrane. When the template molecules are removed, the cavities that match with the spatial configuration of the template are obtained, and then the electrochemical response is obtained when the MIP is combined with the specific template, based on the cavities in the spatial structure and binding sites the electrosignal can be recorded, and the concentration of target molecules can be determined .…”

Computational Design, Synthesis and Application of a New Selective Molecularly Imprinted Polymer for Electrochemical Detection

A computational approach was developed to find a suitable functional monomer to design a new molecularly imprinted polymer (MIP), based on which methacyrlic acid (MAA) was selected as a functional monomer to synthesize the molecular imprinted and non‐imprinted polymers. All calculations were carried out using Gaussian 03 software based on the application of Hartree−Fock (HF) method with 6‐31G (d) basis set. The performance of the MIPs prepared with different ratios of MAA was then evaluated using equilibrium rebinding assays. The MIP with the highest binding capacity was chosen as recognition material for the fabrication of new PVC sensors and their responses were compared with each other and with previously reported modifiers in literature. The addition of the ionic surfactant (TFPB) was found to have a synergistic effect on the response mechanism of the electrodes. The results of the MIP modified sensors show that they provide an improved electrode slope, wider pH range and a highly extended life time reaching 7 months compared to 2–4 weeks in case of traditional ion‐exchangers reported in literature, besides, being successfully applied for measurements in biological samples.
