Preliminary Application

Water-soluble fluorescent carbon nanodots (C-dots) with strong photoluminescence were synthesized on a large scale by a facile, one-step and mild pyrolytic route using ammonium citrate as carbon source. The as-prepared C-dots exhibited low cytotoxicity, excellent biocompatibility and preeminent multicolor photoluminescent properties. Furthermore, the cellular internalization of the obtained C-dots was evaluated and the results reconfirmed the C-dots potentials for bioimaging.
