Spectroscopic study of the effect of temperature on the interaction between CdTeand bovine serum albumins

Based on the unique properties, quantum dots (QDs) have been widely applied in biological and biomedical fields. However, relatively little is known about the interaction of QDs with some important biomolecules. In this paper, CdTe quantum dots modified by a natural biopolymer based on polyacrylamide (PAAm) grafted onto sodium alginate (Alg-g-PAAm) were synthesized in an aqueous solution. Then the effect of temperature onthe interaction between CdTe QDs/Alg-g-PAAm and bovine serum albumins (BSA) was studied using the fluorescence and UV–visible spectroscopy. The fluorescence and UV–visible data revealed that the intensity of FL decreases by increasing the temperature.
