Controlled assembly of gold nanorods induced by Na(3)PO(4) leads to a significant amplification of localized surface plasmon resonance (LSPR) signals. The strong affinity between Au and Hg alters the coupled LSPR signals due to the amalgamation of Hg and Au. This allows detection of Hg in aqueous solutions with ultra-high sensitivity and excellent selectivity, without sample pretreatment.
由 Na(3)PO(4)诱导的金纳米棒的可控组装导致局域表面等离子体共振 (LSPR) 信号的显著放大。由于 Au 和 Hg 的强亲和力，Hg 和 Au 的汞齐化会改变耦合的 LSPR 信号。这使得可以在无需样品预处理的情况下，以超高灵敏度和极好的选择性检测水溶液中的 Hg。
