“…Indeed, NIPs themselves are interesting for some applications [67,68] or have comparable performance to MIPs [69][70][71][72]. Usually they have their own selectivity [73][74][75][76][77] and during the imprinting process, this selectivity and/or their adsorption ability is only slightly improved (if at all). These data from the literature make it likely that MIPs can occasionally be replaced by NIPs in practical applications.…”

A simple and efficient method is presented for assessing molecularly imprinted polymers (MIP) and other sorbents from the point of view of practical applications. The adsorption isotherms of the compounds, which need to be separated or detected in an application, are constructed from a small number of measured points on a log-log chart and then are compared graphically. Despite its simplicity and robustness this method reveals the information needed for optimal selection between MIPs and alternative sorbents. The design of separation or detection methods with MIPs is also supported by the proposed graphical isotherm comparison. Many experimental isotherms are presented supporting the proposed method.

“…Therefore, this approach is well suited for imprinting of biomacromolecules like proteins . Depending on application modes, the solid supports subjected to surface imprinting of proteins can be nanomaterials , electrodes , microspheres , membranes , and monoliths. Molecular imprinting of proteins in polymers attached to the surface of nanomaterials is currently a hot topic; however, this application mainly focuses on the fabrication of biosensors since the nanomaterials exhibit a remarkably large surface‐to‐volume ratio and size‐related physical and chemical properties.…”

A new thermally switchable molecularly imprinted monolith for the selective capture and release of proteins has been designed. First, a generic poly(glycidyl methacrylate-co-ethylene dimethacrylate) monolith reacted with ethylenediamine followed by functionalization with 2-bromoisobutyryl bromide to introduce the initiator for atom transfer radical polymerization. Subsequently, a protein-imprinted poly(N-isopropylacrylamide) layer was grafted onto the surface of the monolithic matrix by atom transfer radical polymerization. Scanning electron microscopy and energy-dispersive X-ray spectroscopy of the cross-sections of imprinted monoliths confirmed the formation of dense poly(N-isopropylacrylamide) brushes on the pore surface. The imprinted monolith exhibited high specificity and selectivity toward its template protein myoglobin over competing proteins and a remarkably large maximum adsorption capacity of 1641 mg/g. Moreover, this "smart" imprinted monolith featured thermally responsive characteristics that enabled selective capture and easy release of proteins triggered only by change in temperature with water as the mobile phase and avoided use of stronger organic solvents or change in ionic strength and pH.

“…These wrinkles may be important for preventing the aggregation of GO and maintaining a high surface area. 37 As observed in Fig. 5b and c, the approximate GO sheets were decorated by the MIPs, which indicated that the imprinted sites were generated in the GO-MIPs hybrid and that the GO-MIPs particles had been successfully synthesized.…”

“…Compared with the morphology of the GO-NIP particles, the GO-MIPs particles showed a high degree of cross-linking because the target molecules provided sites for the polymerization reaction. 37 Fig. 4b-d shows SEM images of the GO-NIPs and GO-MIPs before and aer template elution.…”
