This review focuses on the recent advances in the synthesis of graphene quantum dots (GQDs) and their applications in drug delivery. To give a brief understanding about the preparation of GQDs, recent advances in methods of GQDs synthesis are first presented. Afterwards, various drug delivery-release modes of GQDs-based drug delivery systems such as EPR-pH delivery-release mode, ligand-pH delivery-release mode, EPR-Photothermal delivery-Release mode, and Core/Shell-photothermal/magnetic thermal delivery-release mode are reviewed. Finally, the current challenges and the prospective application of GQDs in drug delivery are discussed.

“…The principle involved is to dehydrate organic biomolecules and then subject them to carbonization. The process involves hydrothermal reaction to dehydrate carbon bonds, followed by the interface of hydrogen bonds of one carboncontaining molecule to adjacent one forming water molecule and final interface with covalent bonds to form GQDs [91][92][93] . Next, Qu and colleagues demonstrated a hydrothermal route to prepare N-GQDs and N, S co-doped GQDs using CA, urea, and thiourea as the source of C, N, and S, respectively 94 .…”

“…The thermochemical decomposition or pyrolysis of citric acid (CA) is a frequently used approach for GQD production. GQDs are efficiently produced at a relatively low temperature (200 °C), in an ambient atmosphere, and within short times (40 min) [ 41 ]. It is observed that the temperature of annealing has an impact on the photoluminescence properties of GQDs.…”

During the last 20 years, the scientific community has shown growing interest towards carbonaceous nanomaterials due to their appealing mechanical, thermal, and optical features, depending on the specific nanoforms. Among these, graphene quantum dots (GQDs) recently emerged as one of the most promising nanomaterials due to their outstanding electrical properties, chemical stability, and intense and tunable photoluminescence, as it is witnessed by a booming number of reported applications, ranging from the biological field to the photovoltaic market. To date, a plethora of synthetic protocols have been investigated to modulate the portfolio of features that GQDs possess and to facilitate the use of these materials for target applications. Considering the number of publications and the rapid evolution of this flourishing field of research, this review aims at providing a broad overview of the most widely established synthetic protocols and offering a detailed review of some specific applications that are attracting researchers’ interest.
