Rapid on-site SERS detection of difenoconazole and flusilazole in environmental water using an AuNSs/COF-based plate

Sampling and SERS detection of pesticides in air and water using a bifunctional PTFE membrane functionalized with high-index Au trisoctahedrons and ZIF-67.

Monitoring of pesticides in air and water is essential for assessing occupational exposure and ensuring environmental safety. In this study, an integrated point-of-use (POU) surface-enhanced Raman scattering (SERS) platform based on a high-index Au trisoctahedrons (Au TOHs)/zeolitic imidazolate framework-67 (ZIF-67)-de...

A derivatization-assisted SERS platform using Au TOHs/hydrogel for point-of-use detection of trace ozone in air

A cost-effective and stable paper-based SERS substrate: DFT-guided design for trace perchlorate detection in goat milk.

This study presents a facile and efficient method for fabricating a paper-based surface-enhanced Raman scattering (SERS) substrate for sensitively determining perchlorate, a persistent environmental pollutant. The fabrication of the substrate involved the formation of a homogeneous silver nanoparticle monolayer on thio...

Ratiometric fluorescence detection of aflatoxin B1 in food samples using metal-organic framework confined within mesoporous silica.

Aflatoxin B1 (AFB1) is a highly toxic and carcinogenic mycotoxin that poses significant threats to food safety and human health. A composite material, formed by confining Zr-based metal-organic framework (Zr-LMOF) within aminated mesoporous silica (ASBA-15) and integrating with Ru(bpy)32+, provides a stable and sensiti...

Cefalexin fingerprinting in water using graphene oxide/gold nanoparticle-modified silica photonic microsphere SERS substrates.

Rapid detection of thiram using a dynamic ratiometric in-tube SPME-SERS strategy.

Surface-enhanced Raman spectroscopy (SERS) is a powerful tool for pesticide detection but is hindered in field applications by slow analyte mass transport and quantitative irreproducibility. Herein, we report an in-tube solid-phase microextraction-SERS (in-tube SPME-SERS) strategy that simultaneously overcomes these bo...
