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).

A simple route is presented for the fabrication of a magnetic β-cyclodextrin/graphene oxide nanocomposite (MCGN). The characteristic results of FTIR, SEM, TEM, VSM and XRD showed that MCGN was prepared. The large saturation magnetization (50.13 emu g−1) of the synthesized nanoparticles allows fast separation of the MCGN from liquid suspension. The MCGN demonstrates extremely fast Cr-removal from wastewater with a high removal efficiency within 60 min. The adsorption kinetic data were best described by a pseudo-second-order model. The Cr-removal capability is more than 120 mg g−1, which is much higher than the previously reported values of other nanomaterials, as Cr-removal adsorbents. The MCGN was stable and easily recovered. The adsorption isotherms were investigated, and indicate that the equilibrium adsorptions are well-described by the Langmuir isotherm mode. The MCGN could be a good candidate for efficient Cr-removal from wastewater and for the deep-purification of polluted water.
