摘要:
Photocatalytic titanium dioxide particles are disclosed having improved dispersibility into an aqueous solvent not only under neutral physiological conditions in vivo but also over a wide pH range, and improved cell affinity and cell uptake property. The photocatalytic titanium dioxide particles comprise particles comprising photocatalytic titanium dioxide and a cationic hydrophilic polymer modifying surfaces of the photocatalytic titanium dioxide particles, wherein the hydrophilic polymer is bonded to the photocatalytic titanium dioxide particles. The photocatalytic titanium dioxide particles are very useful for medical applications, such as destruction of cancer cells.
