In the field of carbon nanomaterials, carbon dots (CDs)
have become
a preferable choice in biomedical applications. Based on the concept
of green chemistry, CDs derived from traditional Chinese medicines
(TCMs) have attracted extensive attention, including TCM charcoal
drugs, TCM extracts, and TCM small molecules. The design and preparation
of CDs from TCMs (TCMs-CDs) can improve the inherent characteristics
of TCMs, such as solubility, particle size distribution, and so on.
Compared with other precursor materials, TCMs-CDs have outstanding
intrinsic bioactivities and potential pharmacological effects. However,
the research of TCMs-CDs in biomedicine is not comprehensive, and
their mechanisms have not been understood deeply either. In this review,
we will provide concise insights into the recent development of TCMs-CDs,
with a major focus on their preparation, formation, precursors, and
bioactivities. Then we will discuss the perfect transformation from
TCMs to TCMs-CDs. Finally, we discuss the opportunities and challenges
for the application of TCMs-CDs in clinical treatment.
