Fusobacterium nucleatum has been employed for the first time to synthesize fluorescent carbon dots which could be applied for the determination of Fe3+ ions in living cells and bioimaging in vitro and in vivo with excellent biocompatibility.
Carbon dots for bioimaging in vitro and in vivo were synthesized from the antineoplastic drug etoposide by a one-step method.
Fluorescent carbon dots were synthesized from milk by microwave cooking and used for two-photon excitedin vitrocell imaging.
A new type of carbon dot (CD) is proposed, which has great potential to be an excellent fluorescent probe for bioimaging in vivo.
