摘要：
Carbon dots（CDs） generally refer to zero-dimensional carbon-based nanomaterials with a particle size of less than 20 nm and rich in functional groups such as hydroxyl， carboxyl and amino groups on their surface. Due to its excellent optical properties and easy functional modification， it has been widely used in biosensing， biological imaging， tumor therapy， antibacterial， and osteogenesis. It is expected to become the most promising carbon-based nanomaterials in the future. However， to truly push CDs to practical applications in biomedicine field， it must be functionalized. Surface passivation and heteroatomic doping are two common methods， and these two methods for functionalization of CDs were systematically summarized in this review. We hope to provide some methods and ideas for the functional design and their practical applications of CDs. © 2022 Chines Academy of Sciences. All rights reserved.
