🚨 The study is relevant to wound healing in humans and mentions hair growth in rats, which could be indirectly related to human hair biology and alopecia research.
Studysummary In this study, a hydrogel wound dressing infused with tannic acid demonstrated excellent antibacterial activity and promoted effective wound healing in rat burn models, leading to wound closure in 17 days and hair regrowth by day 21.

This research article details the synthesis of a flexible hydrogel wound dressing using a biomonomer composed of hydroxyethyl methacrylate, citric acid, and polyethylene glycol (HEMA-CA-PEG). The hydrogel's mechanical properties were confirmed through various tests, and tannic acid (TA) was added to enhance its antibacterial and antioxidant capabilities. The study demonstrated that the TA-containing hydrogel achieved over 99.9% bacterial inhibition and was effective in treating burns on rats, with wound closure observed after 17 days and hair growth by the 21st day. The hydrogel showed promising results in wound healing, promoting granulation tissue formation, re-epithelialization, angiogenesis, and collagen deposition, without any conflicts of interest reported by the authors.
