Outline of Final Research Achievements

We aimed to develop a SERS system for in situ, simple and rapid detection of residual fungicides on agricultural produces by producing a flexible surface decorated by noble metal nano structures and transferring the fungicides by pressing the flexible surface onto the produce. To produce nano structures that can withstand the pressure during the transfer process, we used a galvanic displacement reaction of surface-adsorbed base metal nanoparticles upon exposure to AgNO3 solution. By controlling the size and thickness of the base metal, metal species and reaction temperature, we optimized the silver nano structure on basis of evaluation of SERS spectra of model compounds R6G and BPE. The optimized nano structure was grown on an adhesive tape, which was pressed against an orange treated with 1000 ppm ferbam. Two characteristic peaks at 551 and 1368 cm-1 were detected.

Academic Significance and Societal Importance of the Research Achievements

食の安全は永遠の課題である。輸入される柑橘類等の農作物は、輸送中の劣化を抑制するために、収穫後に防カビ剤で処理されている。関連法案が遵守されていれば健康上の問題はないとされる。しかし、残留基準値(MRL)を越える農薬の使用、使用が認められなくなった農薬、さらに非合法の農薬の使用を防ぐことは急務である。今後、TPP等の条約を通して輸入作物量が増加することが予想されるので、簡便なスクリーニング手法が望まれる。
