Solubilization of [60]fullerene in water by complexation with disaccharides in mixed homogeneous solvent system, is described for the first time. The complexation of extremely water-insoluble [60]fullerene dissolved in non-polar solvent toluene and extremely water-soluble disaccharides dissolved in polar solvent DMSO resulted in an unique self-assembled highly crystalline water-soluble [60]fullerene-disaccharide complex. The interaction between [60]fullerene and disaccharides was found to be non-covalent and were characterized by FTIR, UV-Vis, NMR, XRD, and thermogravimetric analysis. The particle size of the lactose-C-60 complex was found to be monodisperse similar to 60 nm from Transmission Electron Microscopy (TEM) and matched with the size obtained from Static Light Scattering (SLS). Preliminary studies of radical scavenging on the most stable free radical 2,2'-diphenyl-1-picrylhydrazyl (DDPH) suggested that complex has potential biological applications. (c) 2012 Elsevier Ltd.
