Acetic acid has been identified as an early biomarker of salt stress in plants, enabling precise monitoring of plant health and timely detection of stress. However, its rapid and selective detection at room temperature remains challenging. Herein, we report an ionogel capacitive...
Metal oxide semiconductor electronic noses offer a compact and nondestructive method for volatile organic compound (VOC) analysis. However, reliable recognition of multicomponent mixtures remains challenging because of sensor cross-sensitivity, nonlinear adsorption-desorption...
TEA is a highly flammable and neurotoxic volatile organic compound; prolonged exposure can lead to emphysema and even immediate death, making the development of rapid, highly responsive TEA gas sensors an urgent priority. Although tin dioxide (SnO
Olfactory receptors (ORs) are expressed beyond the nasal epithelium and implicated in brain function, yet their roles remain unclear. This study investigated the function of the OR Olfr544, which has been reported to be highly expressed near amyloid plaques in Alzheimer's...
The effect of ultrasound-assisted binary probiotic fermentation on the quality of sugarcane bagasse dietary fiber (SBDF)-added synbiotics yogurt were investigated. The results showed that 0.25Â % (w/v) of SBDF significantly reduced yogurt syneresis. Furthermore,...
Accurate identification of complex gas mixtures in dynamic real-world environments is essential for environmental monitoring, food safety, and public health. However, these challenges arise mainly from overlapping response fingerprints of chemically similar hazardous analytes...
Methane (CH

Trace amine-associated receptors (TAARs) are a class of G protein-coupled receptors with roles in olfaction, behaviour, and immunity. Known best as an olfactory receptor, TAAR5 has been linked to emotional behaviour and hippocampal neurogenesis, yet its peripheral mechanisms...
Wenchang chicken is a famous indigenous breed from Hainan Province, China, and its characteristic flavor is a key determinant of product quality and consumer acceptance. However, differences in volatile flavor profiles among Wenchang chicken lines under standardized rearing and...
In this study, the volatile organic compound (VOC) profiles and sensory quality of pork baozi fillings prepared with different substitution levels of Northeastern Chinese sauerkraut juice were characterized using an electronic nose, electronic tongue, gas chromatography-mass...
Lipid oxidation is a major degradation process in lipid-rich food systems, producing volatile organic compounds (VOCs) associated with rancidity, off-flavours, and reduced shelf life. Although conventional techniques such as gas chromatography-mass spectrometry (GC-MS) provide...
Despite its high nutritional value, the application of Antarctic krill (Euphausia superba, AK) is hindered by complex off-odors. This study integrated electronic nose (E-nose), gas chromatography-ion mobility spectrometry (GC-IMS), and headspace solid-phase microextraction-gas...
Invasive insects inflict severe ecological and economic damage, creating an urgent need for rapid and early detection strategies. Here, we present a biomimetic strategy that replicates the molecular recognition principles of insect olfaction. As a proof of concept, our platform...
Volatile organic compounds (VOCs) are organic compounds having significant impacts on environmental and human health. In this paper, a laser absorption spectroscopy gas sensor system based on an external cavity quantum cascade laser was developed for analyzing multiple VOCs...
Most existing VOC sensors rely on battery power and only single-parameter outputs, limiting long-term deployment, maintenance efficiency, and chemical discrimination. Here, we report a self-powered multivariable photovoltaic sensor (MPVS) that repurposes an organic photovoltaic...
This study aimed to evaluate quality differences between Yunnan upland rice (YNUR) collected in Honghe, Pu'er, Nujiang and Qujing and paddy rice from Jiangxi and Heilongjiang by physicochemical indexes, taste analyzer, sensory evaluation, e-nose, and untargeted metabolomics....
Conductive metal-organic frameworks (c-MOFs) are promising chemiresistive sensing materials for selective gas detection; however, their practical deployment is hindered by insufficient selectivity and humidity-induced performance degradation, both of which stem from poorly...
This study used Attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy, electronic nose, and gas chromatography-mass spectrometry (GC-MS) to investigate the composition of Rugiboletus extremiorientalis changes at different drying temperatures. Molecular...
Electronic noses (e-noses) based on cross-selective gas sensors often suffer from severe redundancy, which degrades odor analysis accuracy and impedes practical deployment. Here, we introduce a fully deep-learning-based sensor array optimization (SAO) framework that learns an...
Fish and seafood freshness can be monitored through volatile organic compounds (VOCs) released during spoilage, especially volatile nitrogenous compounds (VNCs) such as triethylamine (TEA). Consuming spoiled seafood can lead to serious health issues such as food poisoning,...
In the mammalian olfactory bulb, each olfactory receptor neuron type maps to receptor-specific channels called glomeruli. These input axons interact with the apical dendrites of mitral/tufted cells, which are projection neurons that send axons to the olfactory cortex. Therefore,...
This study systematically investigated the interactions between different liposomes and myofibrillar protein (MP), as well as their effects on the gel structure, water-holding capacity, storage stability, and odor properties of surimi gels. The findings revealed that liposomes,...
Microalgae are prolific producers of volatile organic compounds (VOCs) that play important roles in atmospheric chemistry, aquatic ecosystem dynamics, and water quality, particularly through the generation of off-flavours and odors. Despite their ecological relevance and growing...
