In this work, carboxymethylated maltodextrin (Cm-MD) was successfully synthesized as an efficient anionic chiral selector and applied for the enantiomer separation of some basic drugs including tramadol, venlafaxine, verapamil, hydroxyzine, citalopram, fluoxetine, and amlodipine by capillary electrophoresis (CE). The synthesized chiral selector was...

In this work, for the first time, magnetic-phthalated maltodextrin nanosponges (M-PAMDNSs) were synthetized and introduced as efficient and green sorbents. The integration of phthaloyl groups as hydrophobic moieties into networks of maltodextrin nanosponges provided good enrichment for hypothalamic-related peptides (HRPs). The synthesized materials...

In the present work, for the first time, fully green maltodextrin nanosponges (MDNSs) as extraction phases for the preparation of magnetic sorbents were introduced. All of the raw materials and synthetic methodologies used to prepare MDNSs follow the principles of green chemistry. Fluoroquinolones (FQs) (ofloxacin, ciprofloxacin, enrofloxacin, and...

Chirality is a critical issue in pharmaceutics, forensic chemistry, therapeutic drug monitoring, doping control, toxicology, or environmental investigations as enantiomers of a chiral compound can exhibit different activities, i.e., one enantiomer can have the desired effect while the other one can be inactive or even toxic. To monitor enantioselec...

Bisphenol A (BPA) is a synthetic organic compound widely used as a starting material in plastics synthesis. The high toxicity of BPA has promoted the development of effective analytical methods for its separation and detection in complex samples. Herein, a novel magnetic nanocomposite consisting of hydroxyapatite and β-cyclodextrin polymer (MHAP/β-...

Therapeutic peptides have an important effect on physiological function and human health, so it is momentous to quantify and detect low levels of these biomolecules in biological samples for treatment and diagnostic purposes. In the present study, an efficient magnetic solid-phase extraction (MSPE) method was developed based on stearic acid–functio...

In this study, electromembrane extraction (EME) combined with micro-EME (µ-EME) was used for the selective extraction of Cr(VI) from food samples (milk powder, Ocimum basilicum, and fish samples). Electrothermal atomic absorption spectrometry was used for the quantification of Cr(VI). Under the optimized extraction conditions, the extraction recove...

Sample preparation is necessary for the determination of analytes in biological matrices. The presence of endogenous compounds makes biological matrices complex to be analyzed. In recent years, different extraction techniques have been proposed in this area. An innovative approach is solid-phase extraction based on magnetic nanomaterials that can b...

Cyclodextrins (CDs) as a family of cyclic oligosaccharides are toroidal with a hydrophobic interior and a hydrophilic exterior. They are well-known for their ability to form host-guest inclusion complexes with different compounds. They are used as chiral stationary phases in high performance liquid chromatography (HPLC) and gas chromatography (GC)...
