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.

Advancements in food-contaminant detection technologies can significantly improve food safety and human health. Surface-enhanced Raman spectroscopy (SERS) has become the preferred analytical method for food-safety owing to its numerous advantages, which include unique 'molecular fingerprinting' features, high sensitivity, rapid responses, non-invasive characteristics. Raman-signal enhancements rely heavily on high-performance SERS substrates. In recent years, metal-organic framework (MOF)-based substrates have gained attention as promising candidates developing their distinctive structures functions. This review comprehensively examines advances MOF-based substrates, focusing main role of MOFs well typical categories structures, construction methods, representative applications detection.
