Novel one-pot and facile room temperature synthesis of gold nanodots and application as highly sensitive and selective probes for cyanide detection.


PMID 27779114

Abstract

Highly fluorescent gold nanodots have been synthesized through a novel rapid, facile and one-pot room temperature route using trithiocyanuric acid as mild reducing agent and surface ligand. The proposed synthesis overcomes limitations of other synthetic routes in terms of cost, time, complexity and environmental risks, and gives rise to highly fluorescent gold nanodots within 10 min at room temperature, with a maximum emission wavelength at 623 nm and a large Stokes shift (213 nm). Moreover, the synthesized gold nanodots showed a large emission QY (9.62 × 10
