Using electrophoretic co-deposition (EPD), nanocomposite of ball-milled activated carbon and cerium (IV) oxide (CeO2) (or) ceria was prepared as a thin film. Nanocomposite preparation was done and deposited on aluminium foil. Phase analyses were carried out using X-ray diffraction analysis (XRD) showing the uniform compositional profile of the composite. The elemental analysis of ceria, oxygen and carbon was carried out using X-ray photoelectron spectroscopy (XPS). Detailed scanning electron microscopy analysis showed that ball-milled activated carbon, ceria and carbon-ceria composite were formed on the nanoscale and uniformly distributed. The toxicity of activated carbon ceria nanocomposite towards the prostate cancer cell line was evaluated and found to be toxic towards prostate cancer cell lines (PC-3) as analyzed by MTT assay.
