“…Molaei et al synthesized calcium and aluminum‐based layered double hydroxide nanosheets, coated them in situ with PEG, then attached CQDs and folic acid. The composite was then loaded with doxorubicin hydrochloride and the release of the drug was found to be pH‐sensitive (Molaei, 2023). Ostovar et al synthesized a nanocomposite from gelatin, chitosan, and CQDs to study the loading and release characteristics of the anticancer drug, curcumin.…”

The carbon‐based nanostructures have led to the development of theranostic nanoplatforms for simultaneous diagnosis and therapy due to their effective cell membrane‐penetration ability, low degree of cytotoxicity, excellent pore volume, substantial chemical stability, and reactive surface. In the last few years, extensive efforts were made to design multifunctional nanoplatform strategies based on carbon nanostructures, involving multimodal imaging, controlled drug release capabilities, sensing in vitro, efficient drug loading capacity, and therapy. Carbon and graphene quantum dots (CQDs and GQDs) were the recent entrants, contingently being assessed for drug delivery and bioimaging. With the advancements, these quantum dots have ignited remarkable research interest and are now widely evaluated for diagnosis, bioimaging, sensing, and drug delivery applications. The last decade has witnessed their remarkable electrical, optical, and biocompatible properties since their inception. It is presumed that both of them have high potential as drug carriers and would serve as the next generation of approaches to address numerous unresolved therapeutic challenges. This review examined the recent advances of CQD and GQD based drug delivery applications, challenges, and future perspectives to pave the way for further studies in the future.

“…[40][41][42] Several groups fabricated sulfur or nitrogen doped carbon dots as fluorescent probes via a hydrothermal method, which requires a long reaction time (6 h, 8 h, 9 h or even 12 h). [43][44][45][46] In this paper, we used water as a green solvent to synthesize B-CDs with strong blue fluorescence using citric acid and o-phenylenediamine as raw materials via a microwave assisted hydrothermal method. The B-CDs were prepared in 30 min and achieved the selective detection of Fe 3+ .…”

Room‐temperature phosphorescence (RTP) materials have attracted significant attention due to their applications in various fields such as information storage and encryption, organic light‐emitting diode (OLED), sensing, lighting and display, biological imaging, and photodynamic therapy. Traditionally, RTP materials can be efficiently developed using inorganic systems with noble metals or rare earth elements. Recently, many efforts have been devoted to the development of RTP materials based on small organic molecules. The strategies to construct RTP materials include hydrogen bonding, heavy atom effect, n–π* transitions, π–π stacking, donor–acceptor effect, and host–guest doping. Herein, we summarize the recent examples of RTP materials based on small organic molecules primarily focusing on their design strategies and properties. Moreover, their promising applications in information encryption, OLED, as well as bio‐imaging and phototherapy are discussed. The challenges and perspectives are given to provide inspiration toward the future development of organic RTP materials.
