Summary of the invention
The present invention relates to make and use the copper-polyphenol composite nanometer particle formed by green chemical synthesis technology and its system
Preparation Method.For example, the present invention relates to the copper complex nano particle formed by plant extract solution and these copper nanometers
Application of the grain in semiconductor, ceramics, catalyst, sensor and field of medical materials.
Compared with physics, chemistry and microbial process, the present invention is without using toxic chemical as reactant, organic solvent
Or not biodegradable stabilizer, therefore do not have potential danger to environment and biosystem.In addition, this method does not need
The condition of complicated control or very standard, keeps them comparatively inexpensive.
In one aspect, the present invention provides prepare copper-polyphenol composite nanometer particle method.In some embodiments
In, the method includes providing the copper ion of dissolution；Plant extracts is provided, the plant extracts includes chelating agent, polyphenol
Or natural solvent or surfactant；And the copper ion of dissolution and plant extracts are combined and received with preparing copper-polyphenol complex
Rice grain.Einsteinium.For example, the copper ion of dissolution can be provided by dissolving mantoquita in water.For example, dissolution copper ion mentions
The combination of the copper ion and plant extracts of offer or dissolution for, plant extracts can be about to prepare nano particle
Room temperature carries out at around room temperature.For example, room temperature can be the temperature in the sustainable range of the mankind.For example, temperature
Freezing point more than or equal to water and the freezing point less than or equal to water and maximum temperature less than or equal to earth surface Lock-in
Temperature be considered room temperature.For example, room pressure may be greater than or equal to the minimum value occurred on earth surface
Pressure, less than or equal to the maximum value occurred on earth surface.Copper-polyphenol complex nanoparticle can be deposited with effective concentration
In being to apply, for example, the test of semiconductor, ceramics, sensor, medical diagnosis, medical material, targeted delivery of drugs, chemistry are closed
