These results indicate a
gradual weakening of the intermolecular interactions until the network
apparently breaks down around 50–60% (v/v) ethanol. Dilution of
curcumin-GS in ethanol resulted in an increase in curcumin fluores-
cence intensity and a slight blue-shift in emission maximum up to
10–20% (v/v) ethanol followed by a nearly constant fluorescence up to
50% (v/v) ethano
