1. A method for treating a cancer in a subject, comprising administering to a subject in need thereof a pharmaceutical composition comprising a nanomedicinal composition, comprising
a nanocarrier comprising:
a porous silicate and/or aluminosilicate matrix which is at least one selected from the group consisting of particles of mesoporous silica and halloysite nanotubes; and
cerium oxide nanoparticles having a mean particle size of 1 to 20 nm disposed on the porous silicate and/or aluminosilicate matrix; and
a pharmaceutical agent mixture comprising a platinum (II) complex and an antioxidant, the pharmaceutical agent mixture being disposed in the pores and/or on a surface of the nanocarrier, wherein
the nanocarrier has a surface area of 15 to 80 m2/g;
the nanocarrier is substantially free of silanes and organosilicates, and
the cancer is at least one selected from the group consisting of breast cancer, colorectal cancer, and lung cancer.
