摘要
在微乳液中制备出色氨酸-银纳米微粒,并用X射线衍射(XRD),原子力显微镜(AFM),红外光谱(IR)对其结构进行表征。XRD结果表明,色氨酸-银晶粒的平均粒径为27.8nm;从AFM可以看出,色氨酸-银纳米微粒分散性较好;红外可见光谱表明,色氨酸中-COOH,-NH2以及吲哚基上的氮对银(Ⅰ)有直接的配位作用。
Tryptophan-silver(Trp-Ag) nanoparticles in micro emulsion were prepared, the structures of surfaces were characterized by XRD, AFM and IR spectra. XRD results showed that Trp-Ag nanoparticles sizes of diameter were about 27.8 nm. AFM indicated that Trp-Ag nanoparticles dispersed well. The IR results showed that -COOH, -NH2 and indote group of tryptophan formed chemical binding with silver(I).
