Fig. 6: Controllable photothermal therapy applied by the THFOW.

a Schematic illustration of the controllable photothermal therapy in vivo; (b) H&E stained muscle slices harvested from the tissues of mice in contact with PMMA fiber and THFOW; (c) Temperature changes of tumors/muscle monitored by the infrared thermal camera during laser irradiation; (d) Temperature increment during the photothermal therapy of the experimental and control groups (n = 5 biologically independent mice), data were presented as mean ± SD; (e) Schematic illustration of the heat conduction on the tumor site; (f) H&E stained tumor slices harvested from the blank, experimental and control groups after photothermal therapy. A representative image of three independent samples from each group is shown in b and f.
