“…The precision was evaluated via RSDs% of analytical results obtained in intra-and interday tests using two different concentrations (2 and 20 ng/g). The intraday precision was determined by analyzing five replicate samples spiked with seven triazines on the same day (n = 5), while the interday precision was achieved by analyzing these samples once a day 0.010-0.080 0.05-0.28 [35] for 5 consecutive days. The recoveries obtained by the intraand interday analyses were in the range of 79.3-111 and 84.4-110.4%, with the RSDs lower than 4 and 9.6%, respectively.…”

The magnetic metal‐organic framework MIL‐101(Cr) material‐based solid‐phase extraction method coupled with high‐performance liquid chromatography and tandem mass spectrometry was applied to extract seven triazine herbicides in rices. Fe3O4/MIL‐101(Cr) was synthesized using reduction‐precipitation method, in which steps including pre‐synthesis and modification of Fe3O4 nanoparticles were by‐passed. Various parameters including extraction solvent type and volume, ultrasonic extraction time, amount of Fe3O4/MIL‐101(Cr) microspheres, adsorption time, desorption volume and time were investigated. Under optimal conditions, the proposed method had the limit of detection (S/N = 3) and the limit of quantification (S/N = 10) of 1.08–18.10 and 3.60–60.20 pg/g, respectively. Relative standard deviations calculated for all herbicides with concentrations of 2 and 20 ng/g were in the range of 0.5 to 13% (n = 3). In addition, at the two above‐mentioned concentrations, the method achieved relative recoveries percentages of 79.3 to 116.7% when applied to determine the triazine herbicides in real samples spiked. This rapid, green, non‐polluting, pre‐concentrated extraction method was successfully developed and applied to analyze herbicides in rice samples.

The accelerated rising of the world's population increased the consumption of food, thus demanding more rigors in the control of residue and contaminants in food-based products marketed for human consumption. In view of the complexity of most food matrices, including fruits, vegetables, different types of meat, beverages, among others, a sample preparation step is important to provide more reliable results when combined with HPLC separations. An adequate sample preparation step before the chromatographic analysis is mandatory in obtaining higher precision and accuracy in order to improve the extraction of the target analytes, one of the priorities in analytical chemistry. The recent discovery of new materials such as ionic liquids, graphene-derived materials, molecularly imprinted polymers, restricted access media, magnetic nanoparticles, and carbonaceous nanomaterials, provided high sensitivity and selectivity results in an extensive variety of applications. These materials, as well as their several possible combinations, have been demonstrated to be highly appropriate for the extraction of different analytes in complex samples such as food products. The main characteristics and application of these new materials in food analysis will be presented and discussed in this paper. Another topic discussed in this review covers the main advantages and limitations of sample preparation microtechniques, as well as their off-line and on-line combination with HPLC for food analysis.

“…Molecular imprinting technology is a method to synthesis molecularly imprinted polymers (MIPs) which have the recognition sites complementary to the shape and functional groups of the template molecule [1]. With the advantages of easy synthesis, high selectivity and low cost, MIPs have been applied for selective recognition [2,3], solid phase extraction [4,5], liquid chromatography [6][7][8][9], sensing [10,11], catalysis, degradation and drug delivery [12]. Although the molecular imprinting in the field of small molecule was successful, the biomacromolecule including protein [7,13], peptide [14], cell [15] and viruse [16] imprinting technique has been limited due to their large dimensions, chemical and structural complexity, slow mass transfer and environmental instability [17].…”

Magnetic mesoporous silica/graphene oxide based molecularly imprinted polymers for fast selective separation of bovine hemoglobin

et al. 2020

In this work, a facile protein imprinted polymer based on magnetic rich-amine mesoporous silica/graphene oxide was synthesized using dopamine as the functional monomer and bovine hemoglobin as the template molecule. Fe 3 O 4 nanoparticles were introduced onto graphene oxide by an inverse microemulsion method for facilitating surface polymerization dopamine imprinted layer. The protein adsorption test showed that the imprinted layer based on magnetic rich-amine mesoporous silica/graphene oxide can significantly shorten the adsorption equilibrium time of the imprinted polymer toward bovine hemoglobin. Under optimized conditions, the imprinting factor and maximum adsorption capacity of the magnetic imprinted polymer toward bovine hemoglobin was 2.09 and 164.5 mg g −1 , respectively. Several experimental parameters including temperature and pH of solution, type and volume of elution solvent, washing solvent, extraction time were investigated in detail. Combined with magnetic solid phase extraction and high performance liquid chromatography, the magnetic imprinted polymers was successfully applied to rapid separate and enrich bovine hemoglobin from bovine serum with the recoveries of 84.6-102.5%.
