A single gold nanoprobe for colorimetric detection of silver(I) ions with dark-field microscopy

Analyst, 2019, Advance Article DOI: 10.1039/C8AN02397B, PaperYi Fen Xie, Yun Ying Cheng, Meng Li Liu, Hong Yan Zou, Cheng Zhi Huang In this work, the formation of C –Ag+–C bonding between cytosines was utilized to induce interparticle coupling of gold nanoparticles modified with single-strand DNA, resulting in a color change as the signal transduction to quantify Ag+ sensitively under dark-field microscopy imaging, while we achieved the quantification of Ag+ could be directly realized in lake water samples and drug samples.
