Formation of Water-Soluble Fullerenes [C60,C70] under Ultrasonication and Antioxidant Effect

Abstract

The water-soluble fullerenes [C 60 , C 70 ] are prepared with fullerenes [C 60 , C 70 ] and a mixture of oxidants (v/v) at the ratio of 3:1 under ultrasonic condition at room temperature. The MALDI-TOF MS confirmed that the water-soluble compounds were C 60 and C 70 . The antioxidant effect of water-soluble fullerenes [C 60 , C 70 ] in the PC 12 cells (Rat pheochromocytoma) line following exposure to hydrogen peroxide (H 2 O 2 ) was investigated.
