Quantum dots (QDs) have been established in our daily life, for instance, in display screens and light-harvesting technologies, mainly owing to their peculiar opto-electronic features. However, toxicity of inorganic QDs, such as CdSe, CdTe, and perovskites, limits their applications in biological environments for medical diagnosis and bio-imaging purposes. A new generation of QDs called carbon quantum dots (CQDs) have been progressing rapidly over the past few years. CQDs have become as popular as other carbon-based nanomaterials such as carbon nanotubes (CNTs), due to their ease of preparation, ultra-small size, biocompatibility, and bright luminescence.
量子点（QDs）已在我们的日常生活中得到应用，例如在显示屏和光捕获技术中，这主要归功于它们独特的光电特性。然而，无机量子点如硒化镉（CdSe）、碲化镉（CdTe）和钙钛矿的毒性限制了它们在生物医学诊断和生物成像环境中的应用。在过去几年中，新一代的量子点——碳量子点（CQDs）发展迅速。由于易于制备、尺寸超小、生物相容性好和发光明亮，碳量子点已与其他碳基纳米材料如碳纳米管（CNTs）一样受欢迎。
