Method of treating cancer cells using CaMoO4/CaSiO3/g-C3N4 crystalline nanocomposite material

A method of treating cancer cells, comprising:

• incubating a plurality of cancer cells with a particulate crystalline nanocomposite, in an amount sufficient to induce apoptosis or kill at least 60% of the cancer cells, wherein the particulate crystalline nanocomposite comprises:
• a tetragonal CaMoO4 crystalline phase;
• a CaSiO3 crystalline phase;
• and
• a graphitic-C3N4 crystalline phase, wherein at least a portion of the graphitic-C3N4 is in the form of mesoporous nanosheets,
• wherein the cancer cells are breast cancer cells or liver cancer cells,
• wherein a ratio by weight of CaMoO4 to CaSiO3 to graphitic-C3N4 in the particulate crystalline nanocomposite is about (0.8-1.2):(0.8-1.2):(0.8-1.2),
• wherein at least a portion of the CaMoO4 and at least a portion of the CaSiO3 of the particulate crystalline nanocomposite are in the form of substantially spherical particles, and
• wherein the substantially spherical particles have an average particle size of about 5 to about 20 nm,
• wherein the particulate crystalline nanocomposite has a monomodal pore size distribution, as determined by Barrett-Joyner-Halenda (BJH) desorption analysis,
• wherein the particulate crystalline nanocomposite has an average pore diameter of from about 15 to about 25 nm, as determined by BJH desorption analysis, and
• wherein the particulate crystalline nanocomposite has a Brunauer-Emmett-Teller (BET) surface area of from about 60 to about 100 m2/g.
