Oral cancer is a worldwide health issue with high incidence and mortality, demands an effective treatment to improve patient prognosis. Superparamagnetic iron oxide nanoparticles (SPIONs) emerged as a candidate for oral cancer treatment due to their unique attributes, enabling a synergistic combination with its drug-delivery capabilities and hyperthermia when exposed to magnetic fields. SPIONs can be synthesized using biopolymers from agricultural waste like lignin from paddy, which produce biogenic nano iron oxide with superparamagnetic and antioxidant effects.
