Abstract null null The analysis of contaminants in migration of food contact material (FCMs) is an urgent demand for food safety. In this study, melamine and formaldehyde in melamine kitchenware were selectively analyzed by surface-enhanced Raman scattering (SERS) via aptamer/derivatization-based membrane assembly. The membrane assembly was designed by simple filtration of Ag nanoparticles-decorated “stellate” silicon dioxide (SiO2/Ag) and composites of reduced graphene oxide and Ag nanoparticle...

Abstract null null In this work, the hybridization of Co(Ⅲ) doped-CoFe layered double hydroxide and graphene oxide (CoFe LDH/GO) was first employed as catalyst to establish a cataluminescence (CTL) gas sensor for detection of carbon monoxide. In order to obtain Co(Ⅲ) doped-CoFe LDH/GO with the best CTL performance, synthesis reaction parameters including amount of oxidant, oxidation time and amount of GO were studied. The structure and morphology of Co(Ⅲ) doped-CoFe LDH/GO were characterized. Th...

Abstract null null In this work, a native beta-cyclodextrin capped silver nanoparticles decorated Ti3C2Tx nanosheets (Ti3C2Tx-AgNPs@β-CD) surface-enhanced Raman scattering (SERS) substrate was developed by a facile one-pot method. The two-dimensional Ti3C2Tx nanosheets not only acted as the supporter to load AgNPs, but also served as chemical enhancement material. Meanwhile, β-CD played a critical role in the control of morphology and size of AgNPs, and its supramolecular structure also endowed ...

A novel fluorescent probe was designed and synthesized from tetraphenylethene (TPE) and polyhedral oligomeric silsesquioxanes (POSS) via Heck-palladium catalyzed cross-coupling reaction. The as-synthesized TPE functionalized probe performed good solvent stability and selectively preconcentration capability towards target analyte due to its stable structure and the adsorption property. The morphology as well as the physical and chemical properties of the POSS@TPE were carefully characterized. The...

Abstract null null Rapid and high-flux enantiomer separation is significant for drug development. Membrane separation technology provides promising approaches for enantiomer separations. Porous membrane with good selectivity and high permeability is an ideal choice for enantiomer separations. Herein, we demonstrate the preparation of a novel two-dimensional chiral covalent triazine frameworks (CCTF) membrane by “in situ growth” method. Inheriting the strong chirality and specific interactions fr...

Rapid and accurate analysis of multiple targets in complex samples is still a big challenge in the fast detection field. Herein, we developed a rapid and accurate strategy for simultaneous quantification of trace multiple antibiotic residues in complex aquatic samples by surface-enhanced Raman scattering (SERS) using a Ti3C2Tx/DNA/Ag membrane substrate. This membrane substrate was proven to have good uniformity, reproducibility, stability, and SERS activity by a series of characterizations. Also...

Abstract null null In this work, a novel hollow tube covalent organic framework constructed by cyclotricatechylene and tetrafluoroterephthalonitrile (CTC-TFPN-COF) with polyether bond was synthesized, and it was coated on filter membrane for extraction of ultraviolet stabilizer in migration from food contact materials. Since the monomers of the polymer were linked by polyether bond, the CTC-TFPN-COF exhibited strong chemical stability in severe conditions such as acid, alkali and various organic...

Fluorinated covalent organic polymers (F-COPs) constitute a new class of porous materials with a topological structure, large surface area, and potential superiority over other types of polymers in sample preparation. In this study, a F-COP was rapidly synthesized by a simple Schiff-based reaction using 2,3,5,6-tetrafluoroterephthalaldehyde (TFA) and 1,3,5-tris(4-aminophenyl)benzene (TAPB) as monomers, and by adding scandium (Ⅲ) triflate (Sc(OTf)3) as the metal catalyst at room temperature. The ...

Dried fruit foods, including nuts and preserved fruits, are favored by consumers and are rich in protein, lipids, minerals, vitamins, and other nutrients. However, these food products can be contaminated by pesticide residues, heavy metals, mycotoxins, and additives during growth, processing, storage, and transportation. The presence of such pollutants in excess of a certain limit will lead to food safety problems. Therefore, it is of great economic and social significance to strengthen the qual...
