Ultrasensitive and uniform surface-enhanced Raman scattering substrates for the methidathion detection

Ultrasensitive and uniform surface-enhanced Raman scattering substrates for the methidathion detection

In this paper, we proposed a rapid method of detecting Methidathion pesticides by surface enhanced Raman scattering (SERS). In the method, Ag nanoparticles (AgNPs) are synthesized by the modified Tollens technique and deposited on glass slides to become simple detection arrays for SERS detection. Th...
