Pathologic histological analysis of CuS NDs PTT promoting healing effect in MRSA-infected diabetic wound model. (a) Digital images of Masson’s trichrome-stained (db/db) mice dermal wound tissue at day 12 after wounding and collagen distribution (aquamarine blue) in healed skin as per tissue sections, bar = 1 mm. (b) Quantification of the percentage of wound healing area over time. (c) Vertical section of the wound stained between the euangiotic tissues at both ends and the collagen tissue gap (stained with aquamarine blue) after different treatments. (d) Quantification of the collagen tissue thickness. (e) Quantification of the collagen tissue gap.
