FIELD: medicine.
SUBSTANCE: invention can be used for photodynamic therapy method (PDT) of oncology diseases. As nanocomposite photosensitiser, powder consisting of porous silicon particles, including silicon crystals of sizes 2 to 4 nm with fullerene molecules adsorbed on crystal surface (e.g., C60 or C70) is offered, at relative fullerene in nanocomposite 0.3% to 4% by mass. The powder can be used in PTD, as, e.g. aqueous or saline suspension.
EFFECT: photosensitiser is high-effective to generate singlet oxygen, stable to water solutions aggregation, nontoxic for organism.
