Carbon dots as oxidant-antioxidant nanomaterials, understanding the structure-properties relationship. A critical review

Carbon dots (C-dots) are a large family of nanomaterials characterized by an intense photoluminescence. The origin of the emission is multifaceted and is dependent on a number of factors, including structure, surface, and composition. The term "carbon dots" is quite broad and encompasses a wide range of carbon nanostructures. The multiple properties are a result of this variability, which also makes it difficult to establish a clear structure-property relationship. Photoluminescence is the property of this class of nanomaterials that has garnered the greatest attention due to the possibility of applications in various fields, including biotechnologies, electronics, and energy. Another property of C-dots that…
