Novel Water-Soluble Fullerene, Process for Producing the Same and Active Oxygen Generator Containing the Fullerene

摘要

A water-soluble fullerene wherein the number of water-soluble polymers bonded has been regulated can be obtained by coupling water-soluble polymers with a fullerene having functional groups in its molecule via the functional groups. This water-soluble fullerene can be used in the photodynamic therapy or supersonic therapy of cancer through the use thereof as an active oxygen generator.
