Main observation and conclusion ZIF‐8 with excellent chemical and physical properties is a promising material for the field of electrochemical sensing. However, the poor electrical conductivity of ZIF‐8 severely limits its electrochemical performance. Here, we report a method that can significantly improve the conductivity of ZIF‐8 by intercalating Ti3C2Tx MXene as a conductive platform. Benefiting from higher conductivity and unique electrocatalytic activity, the obtained MXene/ZIF‐8 nanocomposite presented the worthy analytical performance for hydrazine sensing. The successful fabrication of MXene/ZIF‐8 holds great promise for the design of electrochemical sensors, and it is a promising material to promote the development of new electrode materials.

“…The accurate extraction of volatiles is critical in this process, and various extraction methods are used for volatile organic compounds for the whole determination (VOCs) in seafood, such as steam distillation (SD) “purge and trap” (P&T) (Conde‐Hernández, Espinosa‐Victoria, Trejo, & Guerrero‐Beltrán, 2017), dynamic headspace (DHS), simultaneous distillation extraction (SDE) (De Frutos, Sanz, & Martínez‐Castro, 1988; Varlet, Prost, & Serot, 2007), vacuum distillation (VD) (Pennarun & Prost, 2002), and solid‐phase microextraction (SPME) (Oh & Shin, 2017). Solid‐phase microextraction (SPME) is a fast, sensitive, and economical method for sample extraction before gas chromatography analysis in comparison with other well‐established techniques for analyzing volatiles in food.…”

This study tested the gel properties, quality of Alaska pollock surimi subjected to different temperature treatments. Results showed that when the heating temperature is 110°C, the water‐holding capacity (WHC) and texture of the surimi and gel strength increased, but as the heating temperature increased, the gel strength decreased significantly (p < 0.05), and ultimately destroyed. The heating temperature had no significant effect on the whiteness of the surimi gel, although it did have a significant effect on volatile components (p < 0.05). Fourier transform infrared (FT‐IR) spectroscopy suggested that with increasing temperature, protein secondary structure of the random coil received maximum damage, leading to protein aggregation and ultimately greatly reduced gel strength. At 100, 105, 110, 115, and 121°C, the surimi gel was determined 37, 46, 49, 52, and 56 volatile components, from of aldehydes, ketones, alcohols, hydrocarbons, and aromatic compounds. These results indicate that heat treatments have an important influence on the gel properties and volatile components of Alaskan pollock surimi gel, and the treatment parameters can be valuable for the production of ready‐to‐use minced fish products.

“…Conventional analytical methods, such as mass spectrometry [6], chromatography [7], electrochemistry [8] and colorimetric assays [9], are powerful tools that offer high sensitivity and specificity for the determination of pesticides; however, their associated high costs, complex sample pretreatment, and time-consuming labor requirements, as well as the low 2,4-D content in typical samples, impede their applications. Subsequently, several fast, cheap, and easy-to-use methods have been developed, including biosensors based on enzymes, aptamers or nucleic acids and enzyme-linked immunosorbent assays [10].…”

A novel molecular imprinting fluorescence sensor was constructed by anchoring mesoporous structured imprinting microspheres on the surfaces of quantum dots (QDs) surface for the selective and sensitive detection of 2,4-dichlorophenoxyacetic acid (2,4-D) on the basis of an electron-transfer-induced fluorescence quenching mechanism. The resulting sensor was well characterized and had ideal spherical morphology and fluorescence properties. Under the optimized conditions, the sensor exhibited a satisfactory linearity within 0.66-80 M, with a low detection limit of 2.1 nM within 20 min. The sensor was successfully applied for the detection of 2,4-D in bean sprout samples, and high recoveries at three spiking levels of 2,4-D, ranging from 95.0 to 110.1%, with precisions below 4.9%, were attained. By taking advantage of surface imprinting and QDs, the sensor exhibited high sensitivity and good selectivity for the separation, enrichment and detection of 2,4-D in real food samples, thereby ensuring food safety.
