(A) Fluorescence spectroscopy of curcumin Fifteen μM curcumin as a) free curcumin in DMSO, b) curcumin-ND in PBS and c) free curcumin in PBS were excited at 420 nm and emission scanned from 430 to 600 nm. (B) Effect of empty ND on the fluorescence intensity of curcumin-ND. Samples included a) curcumin-ND, b) curcumin-ND plus an equivalent amount of empty ND and c) curcumin-ND plus 2 fold excess empty ND.
