“…It is worth mentioning that there were a few particles with diameters near to or exceeding 10 nm, which might be attributed to the stacking of several individual C-dots nanoparticles (particles in the red dotted circle, Figure 1 a. The HRTEM showed an obvious lattice fringe with a lattice spacing distance of 0.21 nm ( Figure 1 a, inset), which could be attributed to the (100) in-plane lattice of graphene [ 23 , 24 ].…”

In this report, red-emissive carbon dots (C‑dots) were facilely prepared from o-phenylenediamine via microwave-assisted hydrothermal treatment. The C-dots demonstrated excitation wavelength-independent emission with maximums at 621 nm that could be effectively quenched by Ag+ via static quenching. This phenomenon was exploited to establish a sensitive fluorescence assay with a low detection limit (0.37 μM) and wide linear range (0–50 μM). In addition, this assay demonstrated excellent selectivity toward Ag+, free from the interference of 16 commonly seen metal ions. Most importantly, the assay demonstrated high reliability toward samples in deionized water, mineral water, lake water, and serum, which could indicate potential applications for Ag+ monitoring in complicated natural and biological environments.

“…265 (e) Condensation of long-wavelength emitting organic molecules/polymers: the CDs prepared by a simple one-step hydrothermal method using indocyanine green inherit the unique NIR emission of the precursor. 266 Although important progress has been made in the excitation and emission regulation of CDs in the red/near infrared region, the development of long wavelength CDs is still in the initial stage. It is necessary to prepare NIR-II fluorescent carbon dots as soon as possible, and the high PCE (photothermal conversion efficiency) of long wavelength light-emitting CDs is also more advantageous in photothermal and photodynamic therapy.…”

“…The luminescence of CDs includes fluorescence, phosphorescence, chemiluminescence, and electrochemiluminescence. Common fluorescing CDs have excitation wavelength dependence, that is, the fluorescence peak position increases with the increase in the excitation wavelength [77–81] . There are also some CDs whose fluorescence is not excitation‐dependent, [82–87] so different CDs may have different luminescence mechanisms.…”

As a multifunctional fluorescent nanomaterial, carbon dots (CDs) not only have small size, stable chemical properties, excellent photoluminescence characteristics, but also exhibit good biocompatibility and low toxicity. It has attracted considerable attention in the field of nanotechnology and biological science. CDs contain abundant functional groups on the surface, which not only retain part of the properties of raw materials, but also may have new photoelectric, catalytic, biomedical, and other functions. In this review, we systematically summarize the synthesis methods, modifications, optical properties, and main biological functions of CDs in recent years. The application of functionalized modified CDs in biological detection, biological imaging, photodynamic therapy, photothermal therapy, targeted therapy, drug delivery, gene delivery, protein delivery, and other biomedical fields is introduced. The latest progress of CDs with its own biomedical function in antioxidant, anti‐pathogen, and disease treatment is summarized. Finally, we discuss some problems in the practical application of CDs and look forward to the future development trend of self‐functional CDs combined with surface modification to achieve multimodal treatment of diseases.
