WATER-SOLUBLE NANOCOMPOSITES WITH FULLERENE C NANOPARTICLES IN POLY-N-VINYLPYRROLIDONE MATRIX AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2024 - IPC A61K9/14 B01J13/00 C01B32/152 C08L39/06 B82B1/00 B82B3/00

Abstract RU 2823484 C1

FIELD: polymer chemistry.

SUBSTANCE: disclosed is a water-soluble nanocomposite as a drug carrier in powder form with long storage life with nanoparticles of fullerene C₆₀ with size from 2 to 50 nm with a face-centered cubic lattice in a poly-N-vinylpyrrolidone matrix with molecular weight from 9 to 300 kDa with fullerene C₆₀ content from 0.48 to 18.42 wt.%. Also disclosed is a method of producing a water-soluble nanocomposite with fullerene nanoparticles.

EFFECT: group of inventions provides avoiding use of toxic solvents, ultrasonic exposure, prolonged dialysis cleaning and obtaining nanocomposites in the form of powder with long storage life.
