Abstract：

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.　The　AgNPs　synthesis　used　in　this　research　is　environmentally　friendly　and　does　not　produce　harmful　substances　to　the　environment.　Through　measuring/investigating　the　SERS　signals　of　Rhodamine　6G　under　different　concentrations,　the　preparation　process　and　process　parameters　of　the　detection　substrate　are　determined.　The　Methidathion　detection　limit　reaches　0.1　ppm　based　on　the　substrates.　This　work　lays　a　foundation　for　preparation　of　large-scale　SERS　detection　arrays　in　the　future.　©　2019　Author(s).
