Multi-spectroscopic techniques to evaluate the toxicity of alloyed CdSeS quantum dots

► Synthesis of alloyed CdSeS QDs in aqueous phase via microwave irradiation. ► Characterization of alloyed QDs by PL, UV-vis, XRD and TEM techniques. ► Evidence of static quenching between alloyed QDs and BSA. ► Evidence of the conformation change of BSA molecules induced by alloyed QDs.
