Most natural waters are probably "ultra dilute": aquasols. While the composition of such waters is routinely characterized thoroughly with respect to composition, very little attention has been paid to the solid phases which are certainly suspended in most, if not all, such. Our recent work having established the importance of the structure of water on its properties, [[1]; R. Roy, W.A. Tiller, I. Bell, M.R. Hoover; Mater Res Innov. 9 (2005) 577.] we have examined the structures of many waters with easily demonstrated (e.g. silver aquasols) or long-claimed (e.g. homeopathic remedies) biological effects. The results show that such materials can be easily distinguished from the pure solvent, and from each other, by the use of UV-VIS and Raman spectroscopy, while FTIR is insensitive to these differences. This opens up a whole new field of endeavor for inorganic materials scientists interested in biological effects.
大多数天然水可能是“超稀溶液”:水溶胶。虽然此类水体的成分通常会依据其组成进行全面表征,但对于固相,即便不是所有此类水体,至少在大多数此类水体中,固相肯定是悬浮的,却很少有人关注。我们近期的工作已经证实了水的结构对其性质的重要性,[[1]; R. 罗伊、W.A. 蒂勒、I. 贝尔、M.R. 胡佛;《材料研究创新》。9 (2005) 577。]我们已经研究了许多具有易于证明(例如银水溶胶)或长期宣称(例如顺势疗法药物)的生物效应的水体结构。结果表明,通过使用紫外可见光谱和拉曼光谱,此类物质能够轻易地与纯溶剂区分开来,并且彼此之间也能区分,而傅里叶变换红外光谱对此类差异不敏感。这为对生物效应感兴趣的无机材料科学家开辟了一个全新的研究领域。
