Ovalbumin as a Precursor for Green Synthesis of Highly Fluorescent Carbon Dots for Cell Imaging

imaging study revealed the CDs had an excellent optical property as well as biocompatibility and thus could be used as a superior fluorescent bioimaging agent. In conclusion, a highly photoluminescent CDs with high solubility, excellent pH and salt stability and low cytotoxicity were synthesized with OVA as a natural precursor. The photoluminescent CDs showed an excellent optical property as well as biocompatibility and thus have a great potential for biomedical applications in the future.
