本研究以電漿法方式改善原先以化學法合成銀奈米粒子於孔洞上負載量低的問題，利用電漿形成高濃度活性自由基的存在下，幫助在同樣具有自由基的MZNs上還原銀奈米粒子，並促進了有機配子石墨烯化的發生，合成奈米銀-氧化石墨烯-沸石複合材料(Ag-GO@MZNs)。與過去使用化學法相比，銀的附載量有大於50倍的顯著提升(0.550 wt%29.20 wt%)，進而使藥物感測有低於100倍的檢測濃度(25000 ppm250 ppm)。電漿法具有簡單合成的的優勢，省去過去實驗室先以化學氣相沉積法在高溫（825°С）氬氣環境下裂解乙烯生成氧化石墨烯後，再以還原劑合成銀奈米粒子，電漿法以一步驟同時生長氧化石墨烯包覆銀奈米粒子。目前已成功應用於咖啡包中主要的毒品成分檢測，可測得10 ppm 下的mephedrone，未來將積極投入結合自動化技術分離尿液中濫用藥物同時作SERS偵測，作為第一現場藥物檢測應用。

In this study, atmospheric pressure microplasma synthesis was used to improve the problem of low loading of silver nanoparticles synthesized by chemical methods on the pores, and to use plasma to form a high concentration of active free radicals to help reduce silver on MZNs that also have free radicals. nanoparticles, and promoted the graphitization of organic gametes, and synthesized silver nanoparticles-graphene oxide-zeolite composites (Ag-GO@MZNs). Compared with the chemical method used in the past, the loading amount of silver has been significantly increased by more than 50 times (0.550 wt% to 29.20 wt%), and the detection concentration of drug sensing is lower than 100 times (25000 ppm to 250 ppm). The microplasma method has the advantage of simple synthesis, eliminating the need to first use chemical vapor deposition in the laboratory to crack ethylene at high temperature (825°С) in an argon environment to generate graphene oxide, and then use a reducing agent to synthesize silver nanoparticles , the plasma method simultaneously grows graphene oxide-coated silver nanoparticles in one step. At present, it has been successfully applied to the detection of the main drug components in coffee pods, and mephedrone can be measured at 10 ppm. In the future, it will actively invest in the combination of automated technology to separate drugs of abuse in urine and perform SERS detection as the first on-site drug detection application.
