“…After the PILs were grafted onto mSiO 2 @nSiO 2 @Fe 3 O 4 nanoparticles, the BET surface area showed a slight decrease (90.89 m 2 /g). At present, nSiO 2 @Fe 3 O 4 nanoparticles without a mesoporous silica layer are commonly used as adsorbents . In this work, nSiO 2 @Fe 3 O 4 nanoparticles were also prepared as a control.…”

Considering that the determination of pyrethroid residues is of value for the safety of food, a new poly(ionic liquid)‐functionalized magnetic mesoporous nanoparticle was designed and used as an adsorbent in magnetic solid‐phase extraction for the enrichment of eight pyrethroids. The porous structure and large surface area of the mesoporous silica shell endow the adsorbent with abundant binding sites. In contrast to the reported poly(ionic liquids) with only one kind of functional group in the cationic part, the new poly(ionic liquids) with mixed cyano and phenyl groups in cationic part matched the chemical structure of the analytes to improve extraction efficiency. Under the optimum conditions, an effective method was established for the determination of eight pyrethroids in apples. Adsorption equilibrium can be quickly reached in 1 min, greatly decreasing the extraction time. The linearity range was found to be 10–200 ng/g, and the detection limits ranged from 0.24 to 1.99 ng/g. Recoveries of analytes in apple samples ranged from 87.3 to 119.0%, with relative standard deviations varying in the range of 3–21.2% (intraday) and 0.3–15.2% (interday). The results indicate that the proposed method is a good candidate for pyrethroid residues in apple samples.

“…Liquid chromatography (LC) with ultraviolet detection provides easier preparation and cost‐effective operation (Alhusban & Ata, 2021), and is used for the determination of neurotransmitters in brain tissues (Wu et al, 2014; Zhao et al, 2021). LC with fluorescence detection has also been applied for the same purpose (Cui et al, 2017; Guo et al, 2021; M. He, Wang, & Wei, 2016; Huang et al, 2018; Huo et al, 2014). However, LC tandem mass spectrometry (HPLC–MS/MS) provides higher sensitivity and selectivity (Al Bawab et al, 2020; Alhusban et al, 2021) and has been employed successfully for the determination of various neurotransmitters in brain tissues (Forgacsova et al, 2018; B.…”

Tobacco smoking is a preventable main cause of fatal diseases. Accurate measurements of the effects it has on neurotransmitters are essential in developing new strategies for smoking cessation. Moreover, measurements of neurotransmitter levels can aid in developing drugs that counteract the effects of smoking. The aim of this study is to develop and validate a fast, simultaneous and sensitive method for measuring the levels of neurotransmitters in rat brain after the exposure of tobacco cigarettes. The selected neurotransmitters include dopamine, GABA, serotonin, glutamine and glutamate. The method is based on high‐performance liquid chromatography–tandem mass spectrometry. Chromatographic separation was achieved within 3 min using a Zorbax SB C18 column (3.0 × 100 mm, 1.8 μm particle size). The mobile phase consisted of HPLC‐grade water and acetonitrile each containing 0.3% heptafluorobutyric acid and 0.5% formic acid at gradient conditions. The linear range was 0.015–0.07, 825–7,218, 140–520, 63.42–160.75 and 38.25 × 103 to 110.35 × 103 ng/ml for dopamine, GABA, serotonin, glutamine and glutamate, respectively. Inter‐ and intra‐run accuracy were in the range 97.82–103.37% with a precision (CV%) of ≤0.90%. The results revealed that 4 weeks of cigarette exposure significantly increased neurotransmitter levels after exposure to tobacco cigarettes in various brain regions, including the hippocampus and the amygdala. This increase in neurotransmitters levels may in turn activate the nicotine dependence pathway.

“…Recently, researchers were developed numerous detection method for mercury ions like atomic absorption spectrometry (AAS), inductively coupled plasma mass spectrometry (ICP-MS), fluorometric, colorimetric, surface plasma resonance and electrochemical methods. [8][9][10][11][12][13][14][15] For all these techniques, peroxidase mimic activity-based assay is the best tool for the detection of mercury ions due to its facile and compatibility mode of detection. Furthermore, peroxidase mimic activitybased assays were mainly fabricated on MoS 2 nanosheets having high peroxidase mimic activity with TMB molecules to improve the sensitivity.…”

This paper presents colorimetric determination of Hg(II) based on MoS2 nanosheets with peroxidase mimics activity. The structure of the this sensor by the peroxidase mimic activity material of MoS2 nanosheets with TMB (Tetramethylbenzidine) solution, the colorimetric detection target of Hg(II) is determined by on-off mechanism using biomolecule of cysteine. The MoS2 nanosheets evaluated by X-ray diffraction, FT-IR and SEM image, confirms formation of a flower like structure. Our results shows that a simple colorimetric detection using peroxidase mimic mechanism can be used to MoS2 nanosheets and determine the Hg(II) in aqueous solution with high sensitivity (10 nM) comparable to those of other nanomaterials. The result suggests that MoS2 nanosheets is a promising new and simple colorimetric sensor for applications in environmental and biological applications.
