“…GQDs can be finally obtained using a variety of macromolecular or small molecular substances [51] as the starting materials through high temperature and pressure [52][53][54][55]. The principle is to break the bonds between carbon materials to form GQDs via high temperature under high pressure [56][57][58][59]. Tian et al [60] used H 2 O 2 to synthesize GQDs in N, N-dimethylformamide (DMF) environment by one-step solvothermal method.…”

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.

“…A very simple method of self-assembly is drop-casting, wherein a drop of colloidal suspension is spread on the desired substrate and allowed to evaporate, which pulls the nanoparticles together. 69,70 Evaporation is also the main characteristic in the vertical deposition method, where a substrate is vertically submerged in a colloidal solution and allowed to evaporate for several days (Fig. 10A).…”

“…GQDs are a 0D material with sizes below 10 nm and characteristics deriving from graphene and carbon dots. GQDs can be readily synthesized by pyrolyzing citric acid and dispersing the carbonized products into alkaline solutions [80], exfoliation [81], and hydrothermal methods [82], among others [80].…”

Nanoengineering biosensors have become more precise and sophisticated, raising the demand for highly sensitive architectures to monitor target analytes at extremely low concentrations often required, for example, for biomedical applications. We review recent advances in functional nanomaterials, mainly based on novel organic-inorganic hybrids with enhanced electro-physicochemical properties toward fulfilling this need. In this context, this review classifies some recently engineered organic-inorganic metallic-, silicon-, carbonaceous-, and polymeric-nanomaterials and describes their structural properties and features when incorporated into biosensing systems. It further shows the latest advances in ultrasensitive electrochemical biosensors engineered from such innovative nanomaterials highlighting their advantages concerning the concomitant constituents acting alone, fulfilling the gap from other reviews in the literature. Finally, it mentioned the limitations and opportunities of hybrid nanomaterials from the point of view of current nanotechnology and future considerations for advancing their use in enhanced electrochemical platforms.
