Water compatible imprinted polymer prepared in water for selective solid phase extraction and determination of ciprofloxacin in real samples

Preparation of hydrophilic molecularly imprinted solid‐phase microextraction fiber for the selective removal and extraction of trace tetracyclines residues in animal derived foods

“…The result was illustrated in Figure 2, with the increase of methanol in solvent, the adsorbed TC amount decreased significantly, and also showed poor extraction performance in methanol and acetonitrile, the maximum adsorption capacity was obtained in aqueous solution. The result was consistent with previous reports [33–35], further indicated our homemade MIP‐SPME fiber is a green and environmental friendly sample pretreatment method.…”

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

“…The maximum adsorption capacity for MINs (37 mg g −1 ) was higher than NINs (8.8 mg g −1 ), which verified the important role of template in the creation of specific cavities in the MINs structure. Generally, in the core-shell MIPs, the core capsulated by the MIPs layer and relatively unavailable for template recognition [24]. Even, if a slight amount of analyte penetrated into the core materials, the sorption mechanism is non-specific, since the core materials don't have specific binding sites.…”

Sample Preparation Using Molecularly Imprinted Polymers

“…40 Boronic acid was also used for its ability to form a reversible covalent complex with cis-diol compounds such as luteolin, 48,49 vitamin B12, 50 sialic acid, 51 or for the specific trapping of glycans of glycoproteins as discussed in more detail below. Many works reported the screening of different synthesis conditions by preparing MIPs using different types of monomers, cross-linkers, template/monomer or monomer/cross-linker ratios, natures of the porogen, 28,30,39,43,[52][53][54][55][56][57][58][59][60][61][62][63][64][65] and even the pH when boronic acid is involved. 50,66 The evaluation of the resulting MIPs consists mainly in comparing the binding capacity of the MIP for the target analyte with the one obtained with the corresponding non-imprinted polymer (NIP) synthesized with the same conditions as the MIP but in the absence of the template molecule.…”

“…101,102 To provide a green synthesis process, another approach consists in preventing the direct use of a toxic cross-linking agent by producing it directly in the polymerization solution, such as it was done for formaldehyde through the hydrolysis of hexamethylenetetramine. 55 The use of ionic liquids as monomer 28,73,80,88 or porogen 103,104 can also be considered as a greener approach than the used of conventional monomers. Deep eutectic solvents (DESs) are also considered as a greenlike material.…”

“…MIP-SPE was recently applied to the trace analysis of target analytes, mainly pesticides, industrial contaminants, and drugs, from real waters, 28,81,83,[90][91][92]131,132,134,136 soil and sediment extracts, 67,73 and food extracts or beverages. 38,54,60,72,82,87,123,124,129,130,133,137,138 It was also used to extract natural products from food or plants 39,[55][56][57]70,86,103,121,127,139 to control their occurrence, such as for toxins, or to purify them.…”
