| 摘要: | 水是存在於地表上最多的化合物質，它與我們的日常生活是息息相關、密不可分的。它的功能性涵蓋的範圍也很廣，無論是在生物、物理與化學應用上，更是扮演著一個不可或缺的角色。而水的一個獨特的特性，主要來自於它擁有一個由氫鍵鍵結的四面體化學結構網，當水被侷限於一個奈米及大小的環境或坐落在某個狹小的介面上時，它的氫鍵鍵結會開始有產生變化，而最一開始由氫鍵鍵結的四面體化學結構網亦會產生一致性的改變。
在本篇研究中，我們對水開創了一個創新的方法，這個方法就是將水的高能量效益儲備起來，並將其能量有效地被應用，並且在常溫下提升水的溶解度、導電性等的相關特性。而本篇主要是利用特定波長光源活化奈米黃金，使其產生表面電漿共振，而後形成之熱電子，這些熱電子進而將由氫鍵鍵結四面體化學結構網的水分子之間的氫鍵打斷或降低其氫鍵鍵結能力，進而形成水分子較小之電漿活化水。
而此種具有高能量的電漿活化水，跟一般的二次水相比較，尤其是在放熱的狀態下，它的鹽類溶解性有更顯著地增加，且當一般的二次蒸餾水在沒有鹽類的狀態下，其導電效益略顯薄弱，此時的電漿活化水卻比一般的二次蒸餾水水有著更顯著的導電效果，而此電漿活化水亦有高滲透性，能夠更有效地進入我們的組織細胞中，將危害分子更完善地代謝出來，亦有抗發炎、抗自由基的效益。將此電漿活化水應用在萃取抗氧化物質時，其能更有效地萃取茶葉中的抗氧化物質epigallocatechin gallate (EGCG)與何首烏中的2,3,5,4’-tetrahydroxystilbene-2-O-beta-d-glucoside (THSG)；且此電漿活化水也會使肥胖老鼠的膽固醇下降，其中以由電漿活化水萃取出來的茶湯，促使老鼠膽固醇更有效地下降。因此，由我們的研究結果顯示，奈米黃金搭配電漿活化制動方式為一種創新，且可提升水多方位功能性可信賴之方法。
Water is the most abundant compound distributing in the world and living being, that is a ubiquitous solvent in biological, physical, and chemical processes. Unique properties of water result from water’s tetrahedral hydrogen-bonded (HB) network (THBN). When water is confined in a nanosized environment or localized at interfaces, the original THBN is destroyed that resulting in corresponding changes in HB-dependent properties.
In this study, the innovative idea of plasmon-activated water (PAW) to validate the reserve energy of high-energy water and applications of high-energy water to promote water’s fundamental activities of solubility, ionic conductivity, and extraction at room temperature is proposed. PAW was created by utilizing hot electrons with energies from the decay of surface plasmon excited at gold (Au) nanoparticles (NPs) for the high-energy water with reduced HBs.
The solubilities of alkali metal-chloride salts in high-energy PAW water were significantly increased, especially for salts that release heat when dissolved that compared to conventional deionized (DI) water. Meanwhile, the ionic conductivity of NaCl in high-energy PAW water was also markedly higher, especially when the electrolyte’s concentration was extremely low. This kind of created water has higher diffusion and mass transfer that could increase the metabolism in tissue. It owns distinct property of anti-inflammatory, also, it is a free radical scavenger. In addition, antioxidative components of epigallocatechin gallate (EGCG) and 2,3,5,4’-tetrahydroxystilbene-2-O-beta-d-glucoside (THSG) from teas and Polygonum multiflorum (PM), respectively, can be more effectively extracted using high-energy PAW water. Moreover, fat mice drinking PAW and drinking green tea dissolved in PAW can effectively decrease cholesterol (CHOL) and glucose (GLU). These results suggest that high-energy PAW water has emerged as a promising innovative solvent for promoting water’s fundamental activities via effective energy transfer. |
