(a) Micro-CT scanning and US detection of legs in all groups: (1) saline with NIR laser, (2) ICG/Fe3O4@PLGA-ZOL NPs without NIR laser, (3) ICG@PLGA NPs with NIR laser, (4) ICG@PLGA-ZOL NPs with NIR laser, (5) ICG/Fe3O4@PLGA NPs with NIR laser, and (6) ICG/Fe3O4@PLGA-ZOL NPs with NIR laser. (b) The bone volumes of the sections of proximal tibia in all groups were analyzed by software. (c) The trabecular numbers of the sections of proximal tibia in all groups were analyzed by software.
