Bisacridinedione-functionalized gold nanoparticles (bisADD-GNPs) were prepared and characterized. Bis-
ADD is a flexible acyclic moiety and a specific Ca2+ sensor. Signaling of the binding events is achieved by
the cation-induced folding of the bisADD-GNPs and the resultant fluorescence enhancement and visual
color change are attributed to the suppression of photoinduced electron transfer (PET) through space
and nano-Au aggregation. The selective binding of Ca2+ is clear from steady state fluorescence and
TEM techniques.
