電漿系統的應用,在材料科學領域是蝕刻、鍍膜的重要設備,近年來在醫學上發展出最新的應用層面。由於電漿蘊藏的能量能夠深入皮膚真皮層進行熱能作用,對緊緻皮膚和改善膚質有顯著效果。本實驗的目的在於建立新形態的大氣電漿整合系統對生物表面進行研究。實驗前期針對氦氣電漿的功率特性進行分析,初步推測氦氣在大流量下(4∼5 slm)電漿提供較高的能量。另一方面,藉由酒精(ethanol,99.9%)和藥用雙氧水(hydrogen peroxide solution,3%)分子鍵結中的氧原子具有很好的氧化能力,對細胞具有殺菌和美白效果,從實驗中亦發現混合兩種氣體在熱能和光譜特性上有明顯變化。後期針對脈衝式電漿與連續式電漿輸出對豬皮組織進行升溫實驗,研判氦氣流量在4 slm,脈衝頻寬50%下會有較好的升溫效果,混合氣體分子在升溫趨勢上也有所不同。相較於連續電漿輸出對組織會有過強的熱破壞,選擇適合的脈衝頻寬和處理時間是未來在人體操作下的重要考量因素。目前實驗設備已經整合在可移動的儀器平台,藉由電腦控制電漿系統的運作,在操作上更具實用和方便性。
