Detailed description of the invention
For the ease of understanding the present invention, further illustrate technical scheme below in conjunction with embodiment.
Namely aforementioned metal nanoparticle according to the understanding on the ordinary meaning of this area, can refer to the size metallic at 1 to 100nm.The kind of metal nanoparticle is not done particularly severe restriction by the present invention, but is noble metal nano particles preferably, because noble metal nano metallic particles stable performance, not easily reacts with solvent etc. in general solution.Metal nanoparticle can be single metal, for instance Au, Pt, Ag, Pd etc.；It is preferably the alloy form containing Au, for instance Au-Pd etc..
What deserves to be explained is, metal nanoparticle can adopt commercially available, it is also possible to according to preparing of this area usual way.For Au nanoparticle, one of which known method can be listed, particularly as follows: with HAuCl4Aqueous solution is Jin Yuan, with NaBH4For reducing agent, under strong alkali environment, (such as NaOH solution) is stirred reduction reaction and obtains.In order to prevent the reunion of nanoparticle in preparation process, stabilizer can be added, for instance CALNN polypeptide.Here, CALNN polypeptide is the polypeptide of 5 amino acid structures, full Cysteine-Alanine-Leucine-Asparagine-Asparagine by name.Its molecular structure is:
, wherein the SH of C end is towards gold nano grain, and the OH of N end is towards solvent.Can make adjustment according to actual needs as its consumption, referential ground is 10 for volume, with the volume of HAuCl4 aqueous solution be 1, NaOH aqueous solution and NaBH4 aqueous solution three's volume be 1 calculating, under the premise that concentration is 1.35mol/l that the concentration that concentration is 0.136mol/l, NaOH aqueous solution of HAuCl4 aqueous solution is 0.136mol/l and NaBH4 aqueous solution.Except aforementioned stable, also can adopt more known surfactants, for instance SDS, SDBS, OP-9, OP-10 etc. and composite, or more known silicone coupling agents, for instance KH560, KH550 etc. and composite.For gold palladium composite nanoparticle, one of which known method can be listed, particularly as follows: with PdCl2Strong acid aqueous solution (such as 0.1mol/L hydrochloric acid) be palladium source, be obtained by reacting under reducing agent at vitamin C under (-5 to 0 DEG C) at cold temperatures.Certainly, in order to avoid the reunion of nanoparticle in preparation process, the identical stabilizer being similar to above-mentioned gold preparation can be adopted.Note; prepared by said method is the metal nanoparticle of solution form; in order to obtain final medium solution; need to isolate the metal nanoparticle of solid particle or solid powdery from the above-mentioned palladium composite nanoparticle containing gold; again the metal nanoparticle of solid particle or solid powdery is dissolved in solvent, namely obtains medium solution.Herein, separation method can be centrifuged processing by the above-mentioned solution containing nano metal particles drying again.
