Here, we report the use of the chemically modified one-step facile hydrothermal process to develop Boron (B), Nitrogen (N), and Phosphorous (P) doped carbon dots (E@CDs). The chemical characterization of the E@CDs was systematically studied by several analytical techniques that confer doping of elements by known characteristics. The obtained E@CDs had observed very homogeneous size distribution and displayed excitation dependent fluorescence properties, and high quantum yield (QY) was measured in case of B and N doping. Excellent cell viability and good cellular uptake was observed for all E@CDs. Finally, E@CDs were compared with pristine CDs on their effect on cell labelling, neural differentiation process and outgrowth of neurite network. By manipulating the doping of CDs, we can control the branching pattern and outgrowth of neuronal developments. The E@CDs are capable due to their photostability biocompatibility, and possible selective affinity towards nanomedicine applications.
