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).
In this paper, carbon dots (CDs) emitting blue fluorescence were prepared using ammonium citrate and ammonium thiocyanate through a low-cost hydrothermal approach.
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.
