Those responsible for the development of sonosensitizers are faced with a dilemma between high sonosensitization efficacy and good biosecurity that limited the development of sonodynamic therapy (SDT). Herein, inspired by the intriguing therapeutic features of SDT and the potential catalytic activity of graphene quantum dots, the potential of N‐doped graphene quantum dots (N‐GQDs) to act as a sonosensitizer...
In article number 2004867, Yiqin Shi, Guqiao Ding and co‐workers demonstrate the superior sonosensitization effect of N‐doped graphene quantum dots, which is believed to be 3–5 times higher than that of traditional sonosensitizers. More importantly, pyrrole N and pyridine N are believed to form catalytic centers in sonochemical processing of N‐doped graphene quantum dots. This knowledge is important...
The extremely complex structure of carbon‐based quantum dots (CQDs) greatly limits the understanding of the solid‐state photoluminescent mechanism of CQDs. In article number 2004621, Siwei Yang, Peng He, Guqiao Ding, and co‐workers summarize the current understanding of the solid‐state photoluminescent (PL) of solid‐state CQDs from the perspective of energy band theory and electronic transitions....
Carbon‐based quantum dots (CQDs), including spherical carbon dots and graphene quantum dots, are an emerging class of photoluminescent (PL) materials with unique properties. Great progress has been made in the design and fabrication of high‐performance CQDs, however, the challenge of developing solid‐state PL CQDs have aroused great interest among researchers. A clear PL mechanism is the basis for...
Graphene quantum dots have attracted the researchers' attention due to its high stability, low cost and controllable photoluminescence performance. In this paper, we report the synthesis of ethylenediamine functionalized graphene quantum dots (E-GQDs). The E-GQDs is synthesized via hydrothermal treatment of the mixed solution of graphene quantum dots and ethylenediamine. The E-GQDs shows remarkable...
