Promoted immune response by IM@ZP under NIR laser irradiation in vivo. A Flow cytometric analysis of CD4 +  and CD8 +  T cells in tumor tissues of mice treated with IM@Z, IM@Z  +  NIR, IM@ZP and IM@ZP  +  NIR. B Flow cytometric analysis of CD8  +  T cells in tumor tissues of mice treated with IM@Z, IM@Z  +  NIR, IM@ZP and IM@ZP  +  NIR. C Flow cytometric analysis of CD4 +  T cells in tumor tissues of mice treated with IM@Z, IM@Z  +  NIR, IM@ZP and IM@ZP  +  NIR. D Flow cytometric analysis of CD8  +  T cell proliferation in tumor tissues of mice treated with IM@Z, IM@Z  +  NIR, IM@ZP and IM@ZP  +  NIR. E Ki67-positive CD8  +  T cells in tumor tissues 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
