Interactions between 4-(2-dimethylaminoethyloxy)-N-octadecyl-1,8-naphthalimide and serum albumins: Investigation by spectroscopic approach

► 4-(2-Dimethylaminoethyloxy)-N-octadecyl-1,8-naphthalimide (DON) was synthesized. ► Effect of solvents on spectral characteristic of DON was investigated. ► Interactions of DON with serum albumin were studied by spectral method. ► A fluorometric method for determination of protein was developed.
