Going Deep into the Surface Chemistry of Carbon Dots: Influence of Functional Groups on the Redox Abilities

Carbon dots are tiny, fluorescent nanoparticles synthesised from cheap, readily available precursors, but for all their promise in catalysis, sensing, and chemical biology, one question has lingered: what actually makes them good at transferring electrons? This study digs into the surface chemistry of carbon dots to show that amine groups — their number, their density, and how accessible they are — are the decisive factor, and that understanding them quantitatively is the key to designing better nanomaterials.

Shining Light on Carbon Dots: New Opportunities in Photocatalysis

Our ChemCatChem Concept Article is now published. The article discusses recent advancements in carbon dots-based photocatalysis. We highlight the link between the carbon dots superficial and core composition and their resulting photo-redox abilities. We then give future perspectives on their application in cutting-edge areas. The work was carried out in collaboration with Dr. Giacomo Filippini and Prof. Maurizio Prato at the University of Trieste.
