Hydrothermal Route

We used a simple hydrothermal route to obtain EDE N-CDs or EIE N-CDs. The fluorescence of the as-prepared CDs could be quenched by cellular Hg2+ owing to the electrons transfer from CDs to Hg2+.

Passivating Agent

Nitrogen-doping of carbon dots enhances their photoluminescent properties but not all amines passivate the surface equally. Indeed, the chemical makeup of the passivating agent is critical in tailoring the physico-chemical and optical properties of carbon dots.
