Carbon dots (CDs) are a specific type of nanomaterial distinguished by their outstanding photoluminescence, biocompatibility, chemical stability, and environmental friendliness. One of the most probable ways to improve their characteristics is doping with metal and non-metal elements. Two primary methods for the synthesis of CDs are top-down and bottom-up approaches. These methods try to assemble chemical structures with tailored properties, such as controlled band gaps, heteroatom doping, and surface functional groups, for diversified application. Ongoing advancement in scientific research is resulting in the discovery of the relationship between structural characteristics of CDs and optical properties. Development in this manner has made it possible to design CDs with enhanced and tailored functionalities. Doping, a milestone in CDs design, is the addition of non-metal or metal components to improve their properties. Non-metal doping is especially well adapted to optimize fluorescence and photocatalytic activity and can be used in a wide range of circumstances. Metal doping has generated significant interest from scientists in recent years as a newly developed nano-engineering technique. Metal doping has been proven to enhance the physicochemical and optical properties of CDs by manipulating their electron density distribution and modifying their bandgap energy. This chapter provides an overview of the metal and non-metals categories and gives a representation of current developments in the biomedical applications of these two classes. This chapter also mentions the opportunities and challenges that can arise with metal- and non-metal-doped carbon dots (CDs) in biomedical and environmental applications. The aim of this chapter is to overcome the existing drawbacks of metal- and non-metal-doped CDs and unleash their full potential for real applications. It is expected that this chapter will provide useful insights into the synthesis and applications of metal- and non-metal-doped CDs and open the doors for future studies and innovations in this area.

摘要

Carbon dots (CDs) are a specific type of nanomaterial distinguished by their outstanding photoluminescence, biocompatibility, chemical stability, and environmental friendliness. One of the most probable ways to improve their characteristics is doping with metal and non-metal elements. Two primary methods for the synthesis of CDs are top-down and bottom-up approaches. These methods try to assemble chemical structures with tailored properties, such as controlled band gaps, heteroatom doping, and surface functional groups, for diversified application. Ongoing advancement in scientific research is resulting in the discovery of the relationship between structural characteristics of CDs and optical properties. Development in this manner has made it possible to design CDs with enhanced and tailored functionalities. Doping, a milestone in CDs design, is the addition of non-metal or metal components to improve their properties. Non-metal doping is especially well adapted to optimize fluorescence and photocatalytic activity and can be used in a wide range of circumstances. Metal doping has generated significant interest from scientists in recent years as a newly developed nano-engineering technique. Metal doping has been proven to enhance the physicochemical and optical properties of CDs by manipulating their electron density distribution and modifying their bandgap energy. This chapter provides an overview of the metal and non-metals categories and gives a representation of current developments in the biomedical applications of these two classes. This chapter also mentions the opportunities and challenges that can arise with metal- and non-metal-doped carbon dots (CDs) in biomedical and environmental applications. The aim of this chapter is to overcome the existing drawbacks of metal- and non-metal-doped CDs and unleash their full potential for real applications.
