An effective method for the synthesis of yolk–shell magnetic mesoporous carbon-surface molecularly imprinted microspheres

Abstract

Uniform and monodisperse Fe3O4@void@C-MIP nanospheres were obtained by surface polymerisation onto the carboxyl modified Fe3O4@void@C carbon materials.

Hydrophilic molecularly imprinted nanospheres for the extraction of rhodamine B followed by HPLC analysis: A green approach and hazardous waste elimination

“…Surface imprinting is a creative strategy in which the specific cavities are located onto or near the surface of the imprinted polymers and could significantly dominate MIPs' limitations. Usually, thin MIPs layer is anchored on the surface of diverse materials [6][7][8][9][10] which are selected according to the functionality, cost, specific surface area, and toxicity. Carbon sphere (CS) has attracted wide interest as an excellent support material due to its exceptional properties such as cheap and wide available natural precursor, multifunctionality, high surface area, low density, physical and chemical stability, eco-friendliness, and excellent biocompatibility [11].…”

Construction of stable core–shell imprinted Ag-(poly-o-phenylenediamine)/CoFe2O4 photocatalyst endowed with the specific recognition capability for selective photodegradation of ciprofloxacin

“…Surface imprinting is an effective approach for synthesizing materials with the specic recognition capability towards the target molecule. [28][29][30][31][32][33][34] Nevertheless, when these common photocatalysts are coated with an imprinted layer, although the selectivity will increase, the photocatalytic activity will greatly decrease due to the coating of the imprinted layer. Therefore, to improve selectivity without reducing photocatalytic activity is a major challenge.…”

Designing and controlling the morphology of spherical molecularly imprinted polymers

“…Therefore, the solid core-mesoporous shell MIPs are widely applied for construction of chemical sensors or target enrichment. Generally Fe 3 O 4 217,218 and SiO 2 [219][220][221][222][223][224][225] are employed as the solid core and the mesoporous shell layer is formed during the molecular imprinting process. The preparation process is similar to that of core-shell MIPs.…”

“…The worm-like channels indicated the mesoporous channels. Inspired by the pioneering work, core-mesoporous shell structured ratiometric fluorescent MIPs were prepared for determination of malachite green, 223 2,4,6-trinitrophenol, 224 diniconazole, 225 etc. Solid Fe 3 O 4 core-mesoporous shell MIPs are usually used for extraction of target from complicated samples.…”
