Under high H2O2 conditions, Fe3+ is reduced to Fe2+ and reacts with DHA to produce C-center free radicals, which kill tumor cells. In addition, ICG produced a warming effect and cytotoxic singlet oxygen with 808 nm laser irradiation.Results: The significant combined antitumor activity of Fe2O3/GCN/ICG/DHA, validated in vitro and in vivo, provides strong experimental support for advancing this transition metal iron-based nanocomplex towards tumor therapy applications.Discussion: It expands the potential applications of novel nanocomplex in the field of tumor therapy. Keywords: nanocomplexes, malignant tumors, chemodynamic therapy, photothermal therapy, photodynamic therapy
