Limitations with solvent exchange methods for synthesis of colloidal fullerenes

• Solvent exchange technique of colloidal fullerene synthesis is further explored.
• Solvent exchange of DMF-C60 is stable in PBS and water, while the THF-C60 is only stable in water.
• Solvent exchange of THF results in partial oxidation and degradation of C60.
• DMF evaporative method results in greater oxidation and degradation of C60.
