Lysine-Assisted Oxygen-Vacancy Engineering of In2O3/TiO2 Nanotube Heterostructures for Room-Temperature Triethylamine Sensing.
Triethylamine (TEA), a representative volatile amine generated during seafood spoilage, is an important indicator for freshness evaluation and food-safety monitoring. However, most chemiresistive TEA sensors still rely on elevated operating temperatures, which limits their practical use in on-site analysis. Here, a roo...
