“…It is a typical method and often uses readily reversible condensation reactions involving boronate esters, 31 ketals/acetals, 32 and Schiff's base. 33 However, covalent imprinting is regarded as a less flexible method since the reversible condensation reactions are limited. Moreover, it is very difficult to reach thermodynamic equilibrium since the strong covalent interactions will result in slow binding and dissociation.…”

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).

“…An ideal template should satisfy three essential conditions: the template should not have functional groups which restrict its polymerization; it should show high chemical stability during the polymerization process and should contain functional groups which can create complexes with functional monomers. Several types of templates such as ions [ 101 , 102 ], organic molecules (pesticides, pharmaceuticals, amino acids, sugars, endocrine disrupting chemicals, etc.) [ 103 , 104 , 105 ], bio-macromolecules, cells and viruses [ 90 , 106 ] have been reported in MIPs, but the imprinting of proteins and a few bio-macromolecules is still a great challenge for researchers [ 107 ].…”

Molecular imprinting is earning worldwide attention from researchers in the field of sensing and diagnostic applications, due to its properties of inevitable specific affinity for the template molecule. The fabrication of complementary template imprints allows this technique to achieve high selectivity for the analyte to be sensed. Sensors incorporating this technique along with surface plasmon or localized surface plasmon resonance (SPR/LSPR) provide highly sensitive real time detection with quick response times. Unfolding these techniques with optical fiber provide the additional advantages of miniaturized probes with ease of handling, online monitoring and remote sensing. In this review a summary of optical fiber sensors using the combined approaches of molecularly imprinted polymer (MIP) and the SPR/LSPR technique is discussed. An overview of the fundamentals of SPR/LSPR implementation on optical fiber is provided. The review also covers the molecular imprinting technology (MIT) with its elementary study, synthesis procedures and its applications for chemical and biological anlayte detection with different sensing methods. In conclusion, we explore the advantages, challenges and the future perspectives of developing highly sensitive and selective methods for the detection of analytes utilizing MIT with the SPR/LSPR phenomenon on optical fiber platforms.

Molecularly imprinted polymers (MIPs) are functional materials capable of molecular recognition and other biorelevant functions and can be prepared with ease in a tailor-made fashion by copolymerization in the presence of a crosslinker and a template molecule (the target molecule or its analog) conjugated with a functional monomer(s). These robust and affordable synthetic polymer receptors are highly accepted as favorable alternatives to biomacromolecules such as antibodies and enzymes. This article provides a critical review of the present state of MIPs to establish perspectives on this technique via a survey of early to contemporary work, mainly conducted by the authors, covering new principles and methodology to generate MIPs. These include the design and synthesis of new functional monomers and crosslinkers to develop and/or introduce new functionalities, new polymerization methods to improve the imprint effect, and highly sensitive MIP-based assays and sensors.
