Abstract

Herein, we designed and synthesized a hybrid material comprising polystyrene submicrobeads coated with silver nanospheres. This material provides a dense collection of electromagnetic hot spots upon illumination with visible light. The subsequent coating with a metal-framework and the adsorption of bathocuproine on it yield an optical sensor for SERS that can specifically detect Cu(II) in a variety of aqueous samples at the ultratrace level. Detection limits with this method are superior to those of induced coupled plasma or atomic absorption and comparable with those obtained with induced coupled plasma coupled with a mass detector.

用金属有机框架和离子选择性染料包覆的等离子体纳米微珠光学定量分析金属离子

在此，我们设计并合成了一种包含涂有银纳米球的聚苯乙烯亚微珠的杂化材料。这种材料在用可见光照射时提供密集的电磁热点集合。随后用金属框架涂覆并在其上吸附巴库丙碱，产生了一种用于SERS的光学传感器，该传感器可以在超痕量水平上特异性地检测各种水样品中的Cu（II）。该方法的检测极限优于诱导耦合等离子体或原子吸收的检测极限，并且与诱导耦合等离子体与质量检测器耦合所获得的检测极限相当。
