Green Synthesis of Reduced Graphene Oxide Using Root Extracts of Asparagus racemosus

Background: The root extracts of Asparagus racemosus (shatamuli) have been used as a benign reducing agent to reduce graphene oxide (GO) and reduced graphene oxide (rGO). The root extract, that is used as a green, reducing agent, is non-toxic, eco-friendly, and naturally therapeutic. Methods: The formation of rGO was identified using XRD, FTIR, TEM, and EDX techniques. Results: The DLS and Zeta potential data revealed that the hydrodynamic size of this rGO is lower than 200 nm with optimal charge. Conclusion: These results may be useful for the use of GO as a probe in biomedical research.
