A fluorometric method was proposed for the determination of Fe3+ and ascorbic acid (AA) based on blue and red dual fluorescence emissions of glutathione (GSH) stabilized-gold nanoclusters (AuNCs).
β-Cyclodextrin modified gold nanoclusters with near-infrared emission were facilely and successfully prepared based on a one-pot and green supramolecular macrocycle modification strategy.
Gold nanoclusters (AuNC) have emerged as a new class of stable and biocompatible photo-emitters. While red emitting clusters comprising ca. 20-25 Au atoms are readily synthesized by several methods, smaller...
Dual-emission ratio fluorescence for selective and sensitive detection of ferric ions and ascorbic acid based on one-pot synthesis of glutathione protected gold nanoclusters
