【Abstract】 [Objective] The research aimed to provide basis for the application of nano-materials in biological field.[Method] The changes of water clusters treated with nano-materials were studied through ultraviolet absorption spectrum and nuclear magnetic resonance spectroscopy.[Result] The light absorption of water treated with nano-materials on ultraviolet absorption spectrum was strengthened at the wave band of 190-325 nm,which indicated that the structure and energy state of water molecule had changed.17O-NMR half-peak width of water became narrow and the chemical shift decreased and moved towards low field.[Conclusion] Water treated with nano-materials had smaller micelle and higher activity.更多还原
