Effective anti-tumor properties of IM@ZP under NIR laser irradiation in vivo. A Tumor volume of mice treated with IM@Z, IM@Z  +  NIR, IM@ZP and IM@ZP  +  NIR. B Representative images showing xenografts in mice treated with IM@Z, IM@Z  +  NIR, IM@ZP and IM@ZP  +  NIR. C Cell apoptosis and pathological changes of tumor tissues in mice treated with IM@Z, IM@Z  +  NIR, IM@ZP and IM@ZP  +  NIR measured by TUNEL and HE staining assays. D Tumor weight of mice treated with IM@Z, IM@Z  +  NIR, IM@ZP and IM@ZP  +  NIR. n  = 6 for mice following each treatment. *p  < 0.05
