Technical synthesis and biomedical applications of graphene quantum dots

Abstract

Graphene quantum dots (GQDs) have generated enormous excitement because of their superiority in chemical inertness, biocompatibility and low toxicity. Due to quantum confinement and edge effects, GQDs have excellent properties, attracting extensive attention from scientists in the field of chemistry, physics, materials, biology, and other interdisciplinary sciences. In this review, we aimed to present a comprehensive view on the synthesis of GQDs for biological applications. We highlighted the potential methods like acid oxidation, hydrothermal and solvothermal reactions, microwave-assisted methods, electrochemical oxidation, as well as pyrolysis and carbonization for successful preparation of GQDs. Meanwhile, four representative types of the biomedical applications based on GQDs, such as bioimaging, biosensing, drug delivery, and antimicrobial materials, were introduced and discussed in detail. This work will be highly useful for quickly getting knowledge and experience for synthesizing various GQDs, and develop advanced strategies for creating novel functional GQD-based nanomaterials for further applications in biomedicine, materials science, analytical science, and optical nanodevices.
