Abstract
成功的燒燙傷創面治療不僅需要快速促進組織再生,還必須有效調控發炎反應並避免過度疤痕形成;而這些面向至今仍是臨床治療的主要挑戰。本研究設計並製備了一種新型混合微複合體(microcomplex, MC),將經微波聚合的聚吡咯(polypyrrole, PPy)—具光熱活性的導電高分子—與 Lactera(LAC,一種具生物活性的黃豆來源成分)整合於同一平台。當接受近紅外光(NIR)照射時,LAC–PPy MC 可產生可控的溫和升溫(mild hyperthermia),進而促進新生血管形成、活化前驅細胞族群,並提升熱休克蛋白的表現。同時,該治療也能調節創傷區域的發炎微環境,促進巨噬細胞朝向修復性的 M2 表型極化。

體外研究顯示,此材料具良好的細胞相容性,且即使在光熱刺激條件下仍能維持芳香烴受體(aryl hydrocarbon receptor, AhR)訊息傳遞的穩定性。進一步在大鼠燒燙傷模型中評估發現,LAC–PPy MC 治療,尤其合併 NIR 照射時,可顯著加速再上皮化(re-epithelialization),改善膠原沉積與排列組織,並降低創面部位的氧化壓力。

綜合而言,本研究提出一個具多重功能的治療平台,能將光熱調控與天然生物活性成分產生協同效應。此策略有望提供一種具前景且具延展性的方式,用於提升燒燙傷修復效率,並推進再生醫學相關應用。
