“…A few types of extraction method are used routinely in analytical toxicology such as liquid-liquid extraction (LLE), 1 liquidliquid micro-extraction (LLE), 2,3 solid phase extraction (SPE), 4 solid-phase micro-extraction (SPME), 5 and molecularly imprinted solid phase extraction (MISPE). [6][7][8] Currently, the most convenient method for extraction of drugs in biological fluids is SPE due to its simplicity and versatility which leaves LLE, which is labor intensive and solvent consuming, far behind in analytical methodologies. MISPE is currently a growing field in clean up techniques for the analysis of biological samples.…”

Herein, we report a magnetic molecularly imprinted polymers (m-MIPs) using Fe 3 O 4 as a magnetic component, carvedilol as a template molecule for the solid-phase extraction (MISPE) as the sample clean-up technique combined with high-performance liquid chromatography (HPLC) and for the controlled release of carvedilol at different pH values of 1.0 (simulated gastric fluid), 6.8 (simulated intestinal fluid), and 7.4 (simulated biological fluid). The adsorption kinetics was modeled with the pseudo-first-order and pseudosecond-order kinetics, and the adsorption isotherms were fitted with Langmuir and Freundlich models. The performance of the m-MIPs for the controlled release of carvedilol was assessed and results indicated that the magnetic MIPs also have potential applications in controlled drug release. Furthermore, the m-MIPs were applied to the extraction of carvedilol from human blood plasma samples. Carvedilol can be quantified by this method in the 2-350 lg L 21 concentration range. The limit of detection and limit of quantification in plasma samples are 0.13 and 0.45 lg L 21. The results from HPLC showed good precision (3.5% for 50.0 lg L 21 ) and recoveries (between 85 and 93) using m-MIP from human plasma samples.
