Transition metal dichalcogenide quantum dots: synthesis, photoluminescence and biological applications
The unique electronic, physical and chemical properties of nanostructured transition metal dichalcogenide (TMD) materials have received great attention, specifically, with the decrease of size to several nanometers, particles named TMD quantum dots (QDs). The inherent properties of TMD QDs make them promising for a variety of applications, including catalytic, luminescence and biomedical. In this review, we first briefly introduce the controlled synthesis of TMD QDs using mechanical exfoliation, ion intercalation-assisted liquid exfoliation, free radical and electrochemical shear and hydrothermal/solvothermal reaction. We then summarize recent progress on chemical and biological applications of TMD QDs in detail.
