“…This leads to the precipitation of magnetite with co-precipitates such as maghemite, hematite, or even goethite, decreasing the magnetic saturation values of nanomaterials and tuning interface properties [ 164 , 165 , 166 ]. Taking into account a magnetic saturation value of magnetic molecularly imprinted composites as a comparable parameter, it was found that the magnetic saturation of nanoparticles formed when only the same system was applied varied significantly from 37.5 emu g −1 [ 167 ] to 82.2 emu g −1 [ 130 ]. The surface disorders, spin canting, and random orientation of spin moments on the surface could explain the variations [ 168 ].…”

Molecular imprinting technology is a well-known strategy to synthesize materials with a predetermined specificity. For fifty years, the “classical” approach assumed the creation of “memory sites” in the organic polymer matrix by a template molecule that interacts with the functional monomer prior to the polymerization and template removal. However, the phenomenon of a material’s “memory” provided by the “footprint” of the chemical entity was first observed on silica-based materials nearly a century ago. Through the years, molecular imprinting technology has attracted the attention of many scientists. Different forms of molecularly imprinted materials, even on the nanoscale, were elaborated, predominantly using organic polymers to induce the “memory”. This field has expanded quickly in recent years, providing versatile tools for the separation or detection of numerous chemical compounds or even macromolecules. In this review, we would like to emphasize the role of the molecular imprinting process in the formation of highly specific siloxane-based nanomaterials. The distinct chemistry of siloxanes provides an opportunity for the facile functionalization of the surfaces of nanomaterials, enabling us to introduce additional properties and providing a way for vast applications such as detectors or separators. It also allows for catalyzing chemical reactions providing microreactors to facilitate organic synthesis. Finally, it determines the properties of siloxanes such as biocompatibility, which opens the way to applications in drug delivery and nanomedicine. Thus, a brief outlook on the chemistry of siloxanes prior to the discussion of the current state of the art of siloxane-based imprinted nanomaterials will be provided. Those aspects will be presented in the context of practical applications in various areas of chemistry and medicine. Finally, a brief outlook of future perspectives for the field will be pointed out.

“…Furthermore, there is evidence from the literature that magnetic DESs are more effective extraction media than traditional DESs. , From the separation of the solute after extraction point of view, deep eutectic solvent molecularly imprinted polymers (DES-MMIPs) have great potential. For example, MMIPs with choline choride/caffeic acid/formic acid used as functional monomers were obtained and successfully used in the extraction and determination of hormones from lotion . When new deep eutectic systems are designed for extraction, their price must be taken into account.…”

There is growing interest in reducing the number of synthetic products or additives and replacing them with natural ones. The pharmaceutical, cosmetic, and food industries are especially focused on natural and bioactive chemicals isolated from plants or microorganisms. The main challenge here is to develop efficient and ecological methods for their isolation. According to the strategies and rules of sustainable development and green chemistry, green solvents and environmentally friendly technologies must be used. The application of deep eutectic solvents as efficient and biodegradable solvents seems to be a promising alternative to traditional methods. They are classified as being green and ecological but, most importantly, very efficient extraction media compared to organic solvents. The aim of this review is to present the recent findings on green extraction, as well as the biological activities and the possible applications of natural plant ingredients, namely, phenolics, flavonoids, terpenes, saponins, and some others. This paper thoroughly reviews modern, ecological, and efficient extraction methods with the use of deep eutectic solvents (DESs). The newest findings, as well as the factors influencing the efficiency of extraction, such as water content, and hydrogen bond donor and acceptor types, as well as the extraction systems, are also discussed. New solutions to the major problem of separating DESs from the extract and for solvent recycling are also presented.
