a IR thermal images of Kunming tumor-bearing mice with tail vein injection of normal saline and FeO/MoS₂-BSA nanocomposites (200 µL, 400 µg mL⁻¹) under 1064 nm laser irradiation (0.75 W cm⁻²) in every minute for 10 min. b Tumor photos harvested from the mices after various treatment at 14th day. c Tumor volume growth on mice measured after different treatments every 2 days for 2 weeks (n = 6, **P < 0.01). d H&E and TUNEL staining of tumor sections harvested from the mice after different treatments at third day (scale bars: 50 μm). e Tumor weight growth on mice measured after different treatments every 2 days within 2 weeks
