“…Compared to bulk polymerization, precipitation polymerization needs a large amount of organic solvents and a very strict control of reaction conditions since a few factors like the polarity of solvents, polymerization temperature and stirring speed have great effects on the polymer particle size. [67][68][69] Monolithic MIPs have also been prepared by a simple, onestep, in situ, free-radical polymerization process within the confines of a chromatographic column without the need for grinding, sieving and column packing. 70,71 By using silane chemistry or surface ''grafting to'' approaches, membranes and molecularly imprinted monolayers are generally formed on an appropriate support of fibers or films.…”

a Molecular imprinting technology (MIT), often described as a method of making a molecular lock to match a molecular key, is a technique for the creation of molecularly imprinted polymers (MIPs) with tailor-made binding sites complementary to the template molecules in shape, size and functional groups. Owing to their unique features of structure predictability, recognition specificity and application universality, MIPs have found a wide range of applications in various fields. Herein, we propose to comprehensively review the recent advances in molecular imprinting including versatile perspectives and applications, concerning novel preparation technologies and strategies of MIT, and highlight the applications of MIPs. The fundamentals of MIPs involving essential elements, preparation procedures and characterization methods are briefly outlined.Smart MIT for MIPs is especially highlighted including ingenious MIT (surface imprinting, nanoimprinting, etc.), special strategies of MIT (dummy imprinting, segment imprinting, etc.) and stimuli-responsive MIT (single/dual/ multi-responsive technology). By virtue of smart MIT, new formatted MIPs gain popularity for versatile applications, including sample pretreatment/chromatographic separation (solid phase extraction, monolithic column chromatography, etc.) and chemical/biological sensing (electrochemical sensing, fluorescence sensing, etc.). Finally, we propose the remaining challenges and future perspectives to accelerate the development of MIT, and to utilize it for further developing versatile MIPs with a wide range of applications (650 references).

“…The advantage of this approach lies in the fact that there is no need for a stabilizer as the MIP particles show no coalescence by virtue of their cross-linking and rigidity [98]. Several factors such as solvent polarity, temperature and stirring speed have a great impact on the MIP particle size [100][101][102]. The main problem associated with this method is the requirement for a large quantity of template dissolved in the excess of solvent [12,27,44].…”

Materials that can mimic the molecular recognition-based functions found in biology are a significant goal for science and technology. Molecular imprinting is a technology that addresses this challenge by providing polymeric materials with antibody-like recognition characteristics. Recently, significant progress has been achieved in solving many of the practical problems traditionally associated with molecularly imprinted polymers (MIPs), such as difficulties with imprinting of proteins, poor compatibility with aqueous environments, template leakage, and the presence of heterogeneous populations of binding sites in the polymers that contribute to high levels of non-specific binding. This success is closely related to the technology-driven shift in MIP research from traditional bulk polymer formats into the nanomaterial domain. The aim of this article is to throw light on recent developments in this field and to present a critical discussion of the current state of molecular imprinting and its potential in real world applications.

“…This approach uses a molecular template to create binding sites in cross-linked polymers by means of free radical polymerization reactions [30][31][32][33][34]. This technology can also be used for preparation of polymers containing inorganic cations selective sites as so-called ion imprinted polymers (IIP).…”
