TUNEL staining for different treatment groups: vehicle plus light exposure (A), blank nanoparticles plus light exposure (B), doxorubicin nanoparticles plus light exposure (C), methylene blue nanoparticles plus light exposure (D), doxorubicin and methylene blue in solution plus light exposure (E), nanoparticles loaded with doxorubicin and methylene blue without light exposure (F), and nanoparticles loaded with methylene blue and doxorubicin plus light exposure (G). Sections were imaged at 100× (I) or 400× (II).
