Carbon dots (CDs) are carbon nanoparticles with a size of less than 10 nm, and are synthesized from various sources; they have been of great interest to scientists worldwide due to their unique optical, electrical, and chemical properties. Sources of carbon are inexpensive and can be classified as a renewable natural resources. Many researchers use CDs because of their low toxicity, better water solubility, high biocompatibility, and stable photoluminescence. The simple methods for producing CDs are hydrothermal and use inexpensive equipment, have low energy consumption, simple manipulation, and one-step preparation. Since the discovery of CDs, researchers have used them in various applications such as sensing, bioimaging, drug delivery, and catalysis. In this review, CDs synthesized from natural resources such as samples from herbs, roots, leaves, flowers, and fruit and some applications are described. This review provides a summary of carbon dots that is expected to provide further information for development of new CDs.
碳点（CDs）是尺寸小于 10nm 的碳纳米颗粒，可由多种来源合成；由于其独特的光学、电学和化学性质，引起了全世界科学家的极大兴趣。碳的来源廉价，可以归类为可再生的自然资源。许多研究人员使用 CDs 是因为它们的低毒性、更好的水溶性、高生物相容性和稳定的光致发光。生产 CDs 的简单方法是水热法，使用廉价的设备，能耗低，操作简单，一步制备。自 CDs 被发现以来，研究人员已经将它们应用于各种领域，如传感、生物成像、药物传递和催化。在这篇综述中，描述了从草药、根、叶、花和水果等天然资源中合成的 CDs 及其一些应用。这篇综述提供了对碳点的总结，有望为开发新的 CDs 提供更多信息。
