摘　　要：Semiconductor quantum dots(QDs),as promising fluorescent materials,have been widely applied in biomedical application due to their unique optical properties.Currently,the most intensively studied are Cd-containing QDs(Cd-based QDs),whose potential toxicity prevents their further commercialization.In recent years,the eco-friendly QDs with low toxicity and environmental friendliness have begun to be developed,showing great potential in biomedical applications.The high-quality synthesis of eco-friendly QDs and the appropriate surface modification are key to realize their applications.This review summarizes the progress of eco-friendly QDs for biomedical applications,including their designed preparation,optical properties,surface modification,toxicity,and their applications in bioimaging and diagnostics.Finally,the challenges of eco-friendly QDs for future bioimaging and diagnostics application were provided.We believe this review will provide important guidance for promoting the development of eco-friendly QDs in bioimaging and diagnostics.
