Abstract

Abstract : Water-soluble hybrid of C60 on ultrathin graphite enables efficient activation of reactive oxygen species for enhanced phototoxicity to neuroblastoma cells. Abstract : Unprecedented nano-carbon hybrids consisting of exfoliated ultrathin graphite (or single-walled carbon nanotubes) with pristine C60 molecules attached on the surfaces have been produced in water in the presence of p -phosphonic acid calix[8]arene. The amphiphilic calixarene plays multiple roles in these processes to provide water dispersibility and π–π interactions with flexible conformations complementing curvatures of the carbon surfaces. The significantly increased water solubility and area of exposure of C60 enable efficient activation of reactive oxygen species for enhanced phototoxicity to SH-SY5Y human neuroblastoma cell line under laser irradiation.
