    摘要: Disclosed is a titanium dioxide composite material which can be dispersed in an aqueous solvent stably and can be administered to a living body in a simple manner and in which the pharmacological effect of a therapeutic compound carried on the composite material can be eliminated by irradiation with light. Also disclosed is a dispersion product of the composite material. The composite material comprises titanium dioxide which has a photocatalytic activity and a therapeutic compound attached to the titanium dioxide through a hydrophilic polymer. The composite material is stable in an aqueous solvent and can be administered to a living body in a simple manner. After the composite material is administered to a living body, a site on the living body where the pharmacological effect of the therapeutic compound is not needed to be developed can be irradiated with light to induce the light excitation of titanium dioxide at the site, thereby decomposing the therapeutic compound to reduce any adverse side effect of the therapeutic compound.

    摘要: Provided is an ultrasonic cancer therapy accelerator comprising titanium oxide-metal complex particles showing a long-lasting antitumor effect imparted thereto while sustaining the dispersibility and catalytic activity thereof which are obtained by dispersing titanium oxide-metal complex particles in an aqueous solvent with the use of a water-soluble polymer and modifying the same with molecules containing a low-valent transition metal via linker molecules having been bound thereto without denaturing the water-soluble polymer. To the titanium oxide surface of titanium oxide-metal complex particles which have been dispersed in an aqueous solvent with the use of a water-soluble polymer, linker molecules are bound via at least one functional group selected from the group consisting of carboxyl, amino, diol, salicylate and phosphate groups followed by the modification with low-valent transition metal-containing molecules via the linker molecules. Thus, an ultrasonic cancer therapy accelerator, which comprises titanium oxide-metal complex particles showing a long-lasting antitumor effect imparted thereto while sustaining the dispersibility and catalytic activity thereof, can be provided. This ultrasonic cancer therapy accelerator, which accumulates in an affected area, can be used as a drug for therapy combined with ultrasonic irradiation.

    摘要: A titanium dioxide composite having a molecular recognition capacity is obtained by modifying the surface of a fine titanium dioxide particle with a hydrophilic polymer in such a manner that titanium dioxide is bonded via an ester bond to a carboxyl group of the hydrophilic polymer and immobilizing a molecule having an ability to specifically bind to a target molecule to the carboxyl residue of the hydrophilic polymer. Due to the molecule distinguishability, this titanium dioxide complex can bind specifically to an endocrine disrupting chemical, a pathogenic factor, a cancer cell and the like and decompose the same by a photocatalytic function.
