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...
