Study of the Förster’s non-radiative energy transfer theory for the interaction between bovine serum albumin and multidendate bioplolymer capped CdS quantum dots

Water-soluble quantum dots (QDs) are used in nanobiotechnology. A polyacrylamide grafted onto kappacarrageenanas a multidendate bioplolymer was successfully applied for coating CdS QDs in aqueous solution. Theobtained QDs were characterized by UV-visible (UV–vis) and fluorescence spectroscopy. After that, the distancebetween coated QDs and the bovine serum albumin (BSA) were evaluated according to the theory of Förster’s nonradiativeenergy transfer theory.
