Intracellular superoxide scavenging by C60-polymer complexes in CATH.a neuronal cells. CATH.a neurons were treated with various concentrations of C60-PVP or C60-PEtOx complexes for 24 h. 200 μM of CMH was added as the cell-permeable spin probe. Superoxide was generated by stimulating neurons with 100 nM of Ang II. CMH radical signal was recorded by EPR spectroscopy over 10 min. EPR signal was normalized to total cell number. **p < 0.01 and *p < 0.05, n = 3.
