摘要：一种新型表面增强拉曼光谱 (SERS) 阵列易于制造，可通过快速、简单且廉价的检测提供强大的增强功能。制备了金纳米颗粒功能化的甲基丙烯酸缩水甘油酯-二甲基丙烯酸乙二酯悬浮液，用于通过注射程序大量制造SERS阵列。对 SERS 阵列的性能和稳定性进行了表征。水溶液中吡虫啉、啶虫脒和噻菌灵的农药浓度分别为 10、0.01 和 0.01 mg L−1。基材的SERS活性可持续5个月。使用 SERS 阵列测定苹果和土豆中的噻菌灵浓度为 0.5 mg kg−1，以及废水中的啶虫脒。该底物可用于快速监测水果和蔬菜上的农药，并可用于废水的质量检查。
ABSTRACT A new surface-enhanced Raman spectroscopy (SERS) array is easily fabricated that offers strong enhancement with rapid, simple, and inexpensive detection. A gold nanoparticle-functionalized glycidyl methacrylate–ethylene dimethacrylate suspension was prepared to fabricate SERS arrays with an injection procedure in large quantities. The performance and stability of SERS arrays were characterized. Pesticides of imidacloprid, acetamiprid, and thiabendazole in aqueous solution were determined at concentrations of 10, 0.01, and 0.01 mg L−1, respectively. The SERS activity of the substrate endured for 5 months. Thiabendazole was determined at 0.5 mg kg−1 in apples and potatoes and acetamiprid in wastewater with SERS arrays. This substrate may have potential for use in rapid monitoring of pesticides on fruits and vegetables and allow quality inspection of wastewater.
