Nanotechnology has been received much attention recently because of their potential for overcoming the limitation of classical mechanics. When the feature size is decreased under visible range, nanometer size, it shows unique behavior optically and mechanically. When the regularly ordered metal particles, which have under incident light dimension, are exposed to the light, those particles trap the incident light and generate surface Plasmon resonance. Due to the recent development of nanotechnology, SPR can be tuned by changing the shape, size and distance of metal particles through various lithography techniques. Many researchers are now trying to find its applications, and one of the most prospective applications of SPR is bio and chemical sensing. On the other hand, Gecko effect is the most important characteristic of nanostructure in mechanical application. Gecko can easily stick to any surface due to their feet which have the unique geometry of micro and nano structure. This surprising adhesion property is considered a major breakthrough in mechanical adhesion research. In this thesis, some novel nanotechnology applications are introduced to optical sensing area and mechanical adhesion area. After a brief explain and overview about whole researches at chapter 1, optical application of nanostructure is discussed at chapter 2. Highly ordered Ag/$SiO_2$/Au layered nanopatterns bring high performance on surface-enhanced Raman scattering (SERS) and its reproducibility. The next chapter is related to the mechanical application of micro and nano structures. Micro line pattern with nanohole array on aluminum surface causes remarkably increased adhesion power with polymer resin. In chapter 2, the highly ordered Ag/$SiO_2$/Au layered nanopatterns that can be used as an efficient surface-enhanced Raman scattering (SERS) active substrate is introduced. The hybrid nanopattern with a silica inter-layer shows large SERS enhancement (up to EF = 3.3×$10^6$) as compared ...
