Abstract: Prospects for successful use of fullerenes in biology and medicine relate to the possibility of obtaining their non-toxic hydrophilic derivatives, which are able to participate in the metabolism occurring in a living organism. An effective solution to this problem is associated with creation of water-soluble molecular complexes, in which the fullerene molecule is enclosed in a larger water-soluble capsule. A new method for producing colloidal suspensions and aqueous dispersions of fullerenes based on vegetable oil and polyvinyl alcohol by ultrasonic dispersion in an Elmasonic S10H chamber has been proposed. Transmission spectra of the synthesized samples were recorded on a UNICO 2100 spectrophotometer. The hydrodynamic radius of particles was measured on a Photocor Compact-Z particle size analyzer. To create theoretical models, as well as carry out quantum chemical calculations, the 3D modeling program ArgusLab 4.0.1 was used. The structures of hydrogel films of fullerene dispersions were studied by scanning electron microscopy (MIRA-LMH microscope from Tescan).
Keywords: colloidal solutions of fullerenes, fullerene dispersions, ultrasonic dispersion, 3D modeling, physical and chemical analysis
