Abstract
Novel luminescent silver nanoclusters (AgNCs) were synthesized utilizing DNA as templates by a simple, rapid and one-pot procedure. Luminescence studies indicated that these DNA-AgNCs exhibited strong emission with peak maximum at 624 nm. The fluorescence of the DNA-AgNCs was found to be quenched by Cu(2+) enabling its detection with high sensitivity and selectivity.
摘要
新型发光银纳米簇 (AgNCs) 是通过一种简单、快速和一锅法利用 DNA 作为模板合成的。发光研究表明，这些 DNA-AgNCs 表现出强烈的发射，峰值最大在 624nm。发现 DNA-AgNCs 的荧光被 Cu(2+) 猝灭，从而使其能够进行高灵敏度和选择性的检测。
