In　this　paper,　we　proposed　a　simple　Surface-Enhanced　Raman　Scattering　(SERS)　detection　method　for　the　possible　pesticide　residues　on　fruit　surfaces.　3-aminopropyl　triethoxysilane　(APTES)　is　used　to　modify　Ag　nanoparticles　(AgNPs)　on　polydimethylsiloxane　(PDMS)　membranes.　The　PDMS　was　attached　to　the　fruit　epidermis　to　adsorb　the　substance,　and　then　the　SERS　test　was　performed　to　analyze　whether　the　epidermis　had　pesticide　residues.　In　the　present　study,　the　AgNPs　were　modified　using　the　Tollens　synthesis　method　while　glucose　was　set　to　be　the　reducing　agent,　and　the　AgNPs　were　synthesized　into　a　uniform　size　of　20-50nm.　In　this　study,　we　fabricated　a　simple　flexible　SERS　substructure,　which　achieved　the　detection　limits　of　R6G　and　Thiram　at　10(-8)　M.　In　the　future,　our　work　can　be　extended　to　biomedical　applications,　or　focusing　on　the　characteristic　substances　that　may　threaten　the　national　defense　and　security,　which　has　a　broad　application　scenario.
