Abstract

Carbon dots were synthesized by a simple and green strategy for selective and sensitive Cu2+ ion detection using both down and upconversion fluorescence. These fluorescent nanosensors show low cytotoxicity and are applied for intracellular sensing and imaging of Cu2+ in biological systems.
