Magnetic molecularly imprinted polymer for the selective extraction of quercetagetin from Calendula officinalis extract

Biocoacervation extraction combined with dispersive solid phase extraction using a reversed-phase core–shell magnetic molecularly imprinted sorbent for 2,4-dichlorophenoxyacetic acid prior to its determination by HPLC

“…Coating the Fe 3 O 4 @SiO 2 MNPs with molecularly imprinted polymers and synthesis of magnetic molecularly imprinted polymers (ma-MIPs) was performed according to the instruction Ma and Shi [23] with modification. Initially, synthesized Fe 3 O 4 @SiO 2 nanoparticles (250 mg) dispersed in anhydrous toluene solution (50 mL, containing 5 mL of MPS).…”

Synthesis, characterization and in vivo drug delivery study of a biodegradable nano-structured molecularly imprinted polymer based on cross-linker of fructose

“…MIPs are highly efficient artificially fabricated receptors which have already found more widespread potential to assist at various field of application such as analytical separation [14] , sensors and biosensor systems [11,15], enantioseparation [16], enzyme like catalysts [17], capillary electrophoresis [18], and many other areas due to their outstanding advantages such as chemical and physical robustness [19], long shelf life [20], reusability [21], predesigned selectivity [22], tailor-made recognition [23], low cost, ease of preparation [24] and so on. MIPs have demonstrated significant extraction capacity due to providing accessibility to recognition sites, fast mass transferring and relatively complete removal of template [25].…”

Selective extraction of Bactrocera oleae sexual pheromone from olive oil by dispersive magnetic microsolid phase extraction using a molecularly imprinted nanocomposite

“…The encapsulation of MNPs into MIPs can create a selective composite polymer with magnetically susceptible characteristics [15]. Hence, they have attracted considerable attention for sample pretreatment [15][16][17][18][19]. Since the sorbent material combines the selectivity of MIPs with the efficiency of NPs, which is based on the increased contact surface of the extraction phase with the sample, an enhanced the extraction rates is obtained.…”

“…This is a simpler alternative compared to filtration or centrifugation. These hybrid sorbent material has allowed the analysis of complex samples, such as seawater [16], fish [17] or spice [18,19], among others.…”
