Fig. 6. Hybrid self-powered treatment for the healing of S. aureus–infected wounds.

Fig. 6.

(A) Schematic representation of wound dressing stimulated by a-TENG and thermocatalyst for healing infected wounds. (B) Schematic diagram of the experimental process throughout the 12-day period. (C and D) Digital photographs (C) and corresponding wound contraction areas (D). (E and F) Agar plating images (E) and survival rates of bacterial cells (F) collected from the wound area for different treatment groups of infected wounds taken on days 0, 3, 6, 9, and 12 for the control, w/o a-TENG, w/ a-TENG, and a-TENG+ ΔT groups. (G and H) H&E, Masson’s trichrome, and IL-6 staining of control (G) and a-TENG+ ΔT (H) groups. (I and J) Quantitative results concerning the thickness of the epidermis (I) and the collagen density (J) in wounds on day 12. Results are plotted as means ± SD (n = 6); *P < 0.05, **P < 0.01, ***P< 0.001, and ****P < 0.0001.
