钛表面金纳米粒子生物医学应用初探
Preliminary studies of creation of gold nanoparticles on titanium surface towards biomedical applications
摘要：
本文介绍了在钛表面制备金纳米粒子的研究结果。我们专注于如何在钛表面上产生具有定义的粒度和分布的金纳米颗粒的问题，这对于几个应用来说可能是有趣的（例如，为生物医学研究提供定义明确的基底等）。要做到这一点，样品受到金纳米颗粒形成的复杂物理路径的影响：通过金离子注入，薄Au层沉积和热退火。通过X射线衍射、扫描电子显微镜和原子力显微镜以及二次中性质谱等方法研究了该技术的效果、对表面结构及其参数的影响。
英文摘要：
This paper is devoted to present the results of creation of gold nanoparticles on titanium surface. We focused on the problem how to create gold nanoparticles on the titanium surface with defined particle size and distribution, which could be interesting for several applications (e.g. providing well-defined substrates for biomedical research, etc.). To do that the sample is affected by the complex physical rout of gold nanoparticles formation: by gold ion implantation, thin Au layer deposition and thermal annealing. The effect of the technology, influence on the surface structure and its parameters were investigated by the X-ray diffraction, Scanning Electron and Atomic Force Microscopy, as well as by Secondary Neutral Mass Spectrometry methods.
