Acetylcholinesterase (AChE) plays crucial roles in numerous physiological processes such as cell differentiation, apoptosis, and nerve tissue developments. Hence, it is highly necessary to design a fluorescent probe for monitoring AChE activity complex living organisms. In this work, near-infrared (NIR) off-on (CyN) was developed detection. CyN exactly synthesized by introducing an N,N-dimethyl carbamyl moiety hemicyanine (CyOH). can "light up" strong NIR fluorescence through cleavage...
The molecular weight, the triple-helix conformation, monosaccharide content, manner of glycosidic linkages, and polysaccharide conjugates polysaccharides all affect bioactivity. purpose this study was to determine how different weights affected bioactivity Lycium barbarum (LBPs). By ethanol-graded precipitation ultrafiltration membrane separation, one oligosaccharide (LBPs-1, 1.912 kDa) two (LBPs-2, 7.481 kDa; LBPs-3, 46.239 were obtained from barbarum. While major component LBPs-1 LBPs-2...
A metal organic framework (MOF-235) was fabricated by a simple solvothermal method and utilized as an adsorbent for the selective removal of electron-rich conjugated dyes.
Due to the similar chemical structures and physicochemical properties, it is challenging distinguish dextran, maltodextrin, soluble starch from polysaccharide products of plant origin, such as Lycium barbarum polysaccharides (LBPs). Using first-order derivatives Fourier-transformed infrared spectroscopy (FTIR, wave range 1800-400 cm-1), this study proposed a two-step pipeline identify adulterated LBPs samples qualitatively quantitatively. We applied principal component analysis (PCA) reduce...
A strategy based on in situ growth of a metal–organic framework composite material was proposed by introducing sodium dodecyl benzenesulfonate (SDBS) group to increase the electrostatic interaction between MOF ligand and silica. In this work, mesoporous silica spheres were first functionalized with zirconium(IV)-based (MOF-808), which produced core–shell particle (MOF-808@silica) as hydrophilic liquid chromatography (HILIC) stationary phase. The obtained improves enhances selectivity...
One of the most important endogenous reactive oxygen species, hypochlorous acid (HClO), is involved in numerous pathological and physiological processes. Herein, a near-infrared fluorescence probe (CyHR) was designed synthesized for ultrafast (within 0.2 s), sensitive (limit detection=39.44 nm), selective response to HClO. The reaction mechanism systematically analyzed by MS, 1 H NMR spectroscopy, HPLC-MS techniques, theoretical calculations. results indicated that HClO can be recognized...
A sensitive and ultrafast ratiometric fluorescence probe for the detection of hydrogen sulfide (H<sub>2</sub>S) in HeLa cells zebrafish.
Lycium barbarum polysaccharides (LBPs) is one of the most important active substances in Wolfberry. It a challenge to quantitatively determine content due their complex structures and lack suitable reference standard practice. In this study, quantitative analysis method LBPs wolfberry was established based on Fourier-transform infrared spectroscopy (FTIR). The stretching vibration -C-O- pyranose ring saccharide at 921 cm-1 selected as characteristic absorption band by theoretical...
