Abstract

It is a challenge to determine selenium in acid aqueous for environmental monitoring and selenium-rich agricultural diagnosis. Herein, we developed a novel localized surface plasmon resonance (LSPR) sensor to detect Se(IV) ions based on the extraordinary laterals etching of gold nanorods (AuNRs). The etching started from the laterals in the low amount of Se(IV) ions, and accompanied by an apparent red shift of the longitudinal plasmon band (LPB), and then transformed to the tips etching with the upward of Se(IV) ions, the LPB band immediately shifted to the shorter wavelength. The red shift change (Δλ) of LPB band was utilized to quantitative analysis instead of blue shift or absorbance intensity, which gave a high selectivity for the proposed sensor. More importantly, this sensor could be performed in 0.1 mol/L of HCl solution, which achieved the seamlessly jointing with the pretreatment of complex samples, without time-consuming pH adjustment.Successful selenium detection was demonstrated in complex soybean samples that collected from the maturity after spraying organic chelated selenium at full flower period. The sensor provided a promising way to monitor and diagnose selenium in complex environmental samples and selenium-rich crops.

用于富硒大豆硒诊断的高选择性局部表面等离子体共振传感器。
如何测定酸性水体中的硒以进行环境监测和富硒农业诊断是一项挑战。在此,我们开发了一种新型局部表面等离子体共振(LSPR)传感器,利用金纳米棒(AuNRs)的非凡侧向刻蚀来检测硒(IV)离子。在Se(IV)离子含量较低时,刻蚀从侧面开始,伴随着纵向等离子体波段(LPB)的明显红移,然后随着Se(IV)离子含量的上升转变为尖端刻蚀,LPB波段立即向较短波长移动。利用 LPB 波段的红移变化(Δλ)进行定量分析,而不是蓝移或吸光度,这就为拟议的传感器提供了高选择性。更重要的是,该传感器可在 0.1 mol/L 的盐酸溶液中使用,实现了与复杂样品预处理的无缝对接,无需费时调节 pH 值。该传感器为监测和诊断复杂环境样品和富硒作物中的硒含量提供了一种可行的方法。
