The interaction of human serum albumin and folic acid was studied using fluorescence spectroscopy, UV absorption and synchronous fluorescence spectroscopy in the pH 7.4 Tris-HCl buffer system at different temperatures. The research shows that these interactions result in the endogenous fluorescence

Epirubicin (Epr) is an effective chemotherapeutic drug; however, the clinical amenability of Epr is limited by its highly toxic interaction with normal cells. This toxicity can be decreased by utilizing nanocarriers and targeted drug delivery systems. This work describes an approach for the delivery
