摘要：The study introduces a spatiotemporal chromatography-mimicking (SCM) e-nose that integrates laser-tailored graphene paper with a microchamber for precise volatile organic compound (VOC) discrimination. The SCM e-nose overcomes traditional array limitations with a single multifunctional component capable of accurate VOC differentiation via chromatography-mimic features. Advanced laser-engraving techniques fabricate a gas-permeable interdigitated electrode from graphene paper as the sieving framework. Key achievements include its single multifunctional component, economical and scalable design, distinct response patterns for different VOCs, remarkable ability to discriminate mixed VOCs, versatility for diverse applications including real-time on-site analysis, and ease of integration with electronic systems. The SCM e-nose represents a significant advancement in electronic nose technology, offering a compact, cost-effective solution for precise VOC detection and analysis.
