1. A method of treating cancer cells, comprising:
exposing the cancer cells to a ZrO2/CaSiO3/g-C3N4 nanocomposite material,
wherein the ZrO2/CaSiO3/g-C3N4 nanocomposite material comprises spherical metal oxide nanoparticles comprising a ZrO2 phase and a CaSiO3 phase dispersed on a matrix of g-C3N4 nanosheets,
wherein the spherical metal oxide nanoparticles have an average particle diameter in a range from 3 to 18 nm, and
wherein the ZrO2/CaSiO3/g-C3N4 nanocomposite material has a percent inhibition for human Breast carcinoma (MCF-7) cells greater than or equal to 80% inhibition in an in-vitro cellular viability assay.
