METHOD FOR PRODUCING AQUEOUS NANODISPERSIONS OF FULLEREN Russian patent published in 2015 - IPC C01B31/02 B82B3/00 B82Y5/00 

FIELD: medicine, pharmaceutics.

SUBSTANCE: invention can be used in the chemical industry, cosmetics and medicine in making cosmetic products, therapeutic agents, antioxidants, antimicrobial agents, radioprotective substances, compounds for gene material delivery. An aqueous nanodispersion of fullerene is produced by solving C₆₀ fullerite crystals in N-methylpyrrolidone. The prepared solution is mixed with water and a stabilising agent, which is presented by amino acid, monosaccharide, peptide, polyvinylpyrrolidone or glycerol. That is followed by the dialysis of the prepared mixture. After the dialysis, the solution can be concentrated, e.g. by vacuum vaporisation. The process is safe as uses no toxic solvents.

EFFECT: simplifying the process by eliminating the use of pre-milled fulleren crystals, ultrasonic treatment and heating.
