Volatile organic compounds (VOCs), particularly monoaromatic hydrocarbon (MACHs), pose a potential risk to the atmospheric environment and human health. Therefore, progressive development of efficient detection methodologies is pertinent need, which still challenge at present. In this study, we present rapid sensitive method detect trace amounts MACHs using bifunctional SERS composite substrate. We prepared an Au/SiO2 enhanced layer porous Cu(OH)2 adsorption via microfluidic-assisted gas-liquid interface self-assembly. The substrate effectively monitored changes in benzaldehyde time-varying spectra, track-specifically identified various VOCs such as benzene, xylene, styrene, nitrobenzene. general, exhibited response time 20 s gaseous benzaldehyde, with minimum concentration less than 500 ppt. Further experimental assessments revealed optimum thickness surrounding 150 nm, can achieve MACHs. Furthermore, recoverable reusable property highlights its practicality. This study presents straightforward approach for detecting SERS, significant implications designing substrates other VOCs.

Putrescine and cadaverine are significant volatile indicators used to assess the degree of food spoilage. Herein, we propose a micro-nano multi cavity structure for surface-enhanced Raman spectroscopy (SERS) analyze gas putrescine in decomposing food. The MoS 2 nano-flowers inserted into PVDF micro-cavity through in-situ growth, followed by vacuum evaporation technology Ag nanoparticles form an Ag/MoS nano-flower cavity/PVDF micron-bowl (FIB) substrate. can improve capture capacity both light gas, thereby exhibiting high sensitivity (EF = 7.71 × 10 7 ) excellent capability detection 2-naphthalenethiol. SERS detections achieved spoiled pork samples with FIB Therefore, this substrate provide efficient, accurate, feasible method specific quantitative safety field.
