“…In addition to UV and MS detection, other detection systems have been used in CE in the period of time reviewed in this article with the aim of determining different types of antibiotics. LIF , light emitting diode‐induced fluorescence detector (LED‐FLD), , photoluminescence , chemiluminescence , ECL , amperometric detection (AD) , and C 4 D were employed (see Table ).…”

“…Photoluminescence as selective sensing in CE was investigated by Khan et al. who studied the kanamycin effect on thioglycolic acid modified CdTe quantum dots (TGA‐CdTe QDs) . A borate buffer at pH 8.0 was selected in order to obtain intense signal measured from the QDs and to provide good buffer capacity at low concentration (in this case 5 mM).…”

Natural, synthetic or semisynthetic antibiotics are highly used to prevent or treat diseases in humans and animals, and to promote animal growth. This fact makes that antibiotics residues or their transformation products may be present in food or in the environment after human or animal excretion. For this reason, it is imperative to develop reliable and sensitive analytical methodologies for their analysis. The main aim of this work is to present and discuss the most recent applications of capillary electromigration methods for the analysis of antibiotics, including the developments and applications of their use as chiral selectors in CE. The literature published from June 2015 to June 2017 is included following the previous review by Domínguez‐Vega et al. (Electrophoresis, 2016, 37, 189–211). Information about the use of different detection systems, off‐line and on‐line strategies to improve sensitivity, and microchip devices for the analysis of antibiotics is provided and properly discussed.

“…The synthesis of the molecularly imprinted polymer (using kanamycin sulfate as template) was made using the sol-gel process [110]. Initially an amount of 500 mg of kanamycin sulfate was dissolved in 6 mL deionized water, where it was added 400 μL of HCl 1.0 mol L -1 aqueous solution(as catalyst), 3200 μL of (3-aminopropyl) trimethoxysilane (APTMS) and 2650 μL of tetraethyl orthosilicate (TEOS).…”

“…In Figure 3.3 the infrared spectra of the MIP are shown after the cleaning steps compared to the spectrum of the template molecule. In the infrared spectrum of the MIP it can be seen that the characteristic peaks of kanamycin (template molecule) are absent after cleaning, where the characteristic infrared bands of the polymer are dominant: 3307 cm -1 (NH 2 from the APTMS); 2956-2889 cm -1 (CH 2 from the APTMS); 1120 and 1033 cm -1 (stretching of C-O from ether and Si-O-Si stretching) and 781 cm -1 (Si-C stretching) [110]. The microscopy of produced MIP after cleaning is shown in…”

With the combined surface imprinting technique and immobilized template strategy, molecularly imprinted magnetic nanoparticles were successfully prepared and coupled with high-performance liquid chromatography to selectively separate and determine gallic acid from the pomegranate rind. On the surface of carboxyl-functionalized magnetic nanospheres, thin imprinting shells were formed using dopamine as monomer and crosslinker. The characteristics, polymerization conditions, and adsorption performances of the resultant nanomaterials were investigated in detail. In addition of good crystallinity, satisfactory magnetism, and uniform morphology of the obtained polymers, they had rapid binding kinetics, high adsorption capacity, and favorable reusability. In the mixed solution of four hydroxybenzoic acids, the prepared nanomaterials have an excellent selectivity to gallic acid with an imprinting factor of as high as 17.5. Therefore, the polymers have great potentials in specific extraction and enrichment of gallic acid from the complex natural resources.
