Development of quantum dot fluorescent probes/contrast agents

Iron-based nanoparticles can not only be used in sensitizers or absorbers but also retain excellent electrical conductivity, optical, electrical, and magnetic properties. So far, very few synthetic methods are known to implement stable Iron-based nanomaterials. We propose to develop novel synthesis routes to produce QDs. In addition, we plan to develop surface modification processes to improve the performance of QDs, and to precisely analyze the effects of surface modification on structural and chemical properties according to the surface/interface/depth by various spectroscopic methods. The development of new biocompatible probes, including in-vivo imaging using MRI, provides a breakthrough technology that enables the early diagnosis of many intractable diseases. The biotoxicity and stability of nanomaterials are important for use in biotechnology and medicine. We also propose to develop low-cost synthetic methods, solve toxicity using Fe-based quantum dot synthesis.
