“…Along with MIP NPs, other examples of the fruitful coupling of nanotechnology and imprinting technology have been illustrated in several works exploiting the integration of MIP film with both metallic [ 92 , 123 , 168 ] and carbon-based [ 55 , 88 , 169 , 170 ] nanomaterials in order to exploit their well-known properties in signal transduction, due to their increased surface area, remarkable conductivity, and excellent catalytic activity, all key elements in the design of an electrochemical sensor. The documented multifunctional properties of these nanomaterials, including high conductivity, interactive functions at the surface, and large surface-to-volume ratios, have indeed proved to increase sensing sensitivity [ 97 , 98 , 171 – 173 ].…”

Looking at the literature focused on molecularly imprinted polymers (MIPs) for protein, it soon becomes apparent that a remarkable increase in scientific interest and exploration of new applications has been recorded in the last several years, from 42 documents in 2011 to 128 just 10 years later, in 2021 (Scopus, December 2021). Such a rapid threefold increase in the number of works in this field is evidence that the imprinting of macromolecules no longer represents a distant dream of optimistic imprinters, as it was perceived until only a few years ago, but is rapidly becoming an ever more promising and reliable technology, due to the significant achievements in the field. The present critical review aims to summarize some of them, evidencing the aspects that have contributed to the success of the most widely used strategies in the field. At the same time, limitations and drawbacks of less frequently used approaches are critically discussed. Particular focus is given to the use of a MIP for protein in the assembly of electrochemical sensors. Sensor design indeed represents one of the most active application fields of imprinting technology, with electrochemical MIP sensors providing the broadest spectrum of protein analytes among the different sensor configurations.

“…MIPs can be customized according to the molecular structure of the target to have specific recognition characteristics, which are very suitable for the identification of sensor components [39,40]. MIPs were created through the polymerization of a functional monomer in the presence of an analyte template [41], such as pyrrole, ethyl 3-coumarincarboxylate, p-aminobenzoic acid, etc.…”

Carbon-based nanomaterials have become the subject of intensive interest because their intriguing physical and chemical properties are different from those of their bulk counterparts, leading to novel applications in smart sensors. Mycotoxins are secondary metabolites with different structures and toxic effects produced by fungi. Mycotoxins have low molecular weights and highly diverse molecular structures, which can induce a spectrum of biological effects in humans and animals even at low concentrations. A tremendous amount of biosensor platforms based on various carbon nanocomposites have been developed for the determination of mycotoxins. Therefore, the contents of this review are based on a balanced combination of our own studies and selected research studies performed by academic groups worldwide. We first address the vital preparation methods of biorecognition unit (antibodies, aptamers, molecularly imprinted polymers)-functionalized carbon-based nanomaterials for sensing mycotoxins. Then, we summarize various types of smart sensors for the detection of mycotoxins. We expect future research on smart sensors to show a significant impact on the detection of mycotoxins in food products.
