Abstract
In the last decade, carbon dots (C-dots, CDs) or carbon quantum dots (CQDs) have attracted a considerable amount of attention from the scientific community as a low cost and biocompatible alternative to semiconductor quantum dots. In particular, doped C-dots have excellent fluorescent properties that have been successfully utilized for numerous applications. In this minireview, we overview the recent advances on the synthesis of doped C-dots derived from carbon-rich sources and their potential applications for biomedical and sensing applications. In addition, we will also discuss some challenges and outline some future perspectives of this exciting material.
Highlights
Carbon dots were first discovered in 2004 during single-walled carbon nanotubes purification [1]

As it was demonstrated by several studies, the fluorescent properties of C-dots can be efficiently applied for in vivo imaging [59,60]
Excitation-dependent C-dots were injected into a mouse and fluorescent images were collected at different excitation wavelengths (Figure 6)
Summary
Carbon dots were first discovered in 2004 during single-walled carbon nanotubes purification [1]. 2. Synthesis and Optical Properties of Doped C-Dots Considering the enormous potential of C-dots for numerous applications, it is extremely necessary to develop their large-scale synthesis.
