奈米材料的製備最近受到廣泛的討論。奈米材料的研究範圍涵蓋包括金屬、非金屬、高分子材料、磁性材料等。在此粒徑範圍的粒子擁有一般巨觀材料所無法比擬的特殊性質。例如低熔點、高延展性、硬度、導電、導熱性質。
在眾多的金屬奈米材料當中，因為銀奈米粒子具有相較於其他金屬優良的導電性、抗菌性、光學性質、以及作為氧化反應的催化效果，因而受到廣泛的研究興趣。例如，表面增強拉曼光譜(SERS)，是微觀分析的一件強有力的工具，因為它提供關於局部的共振訊息，使用銀奈米材料可以使表面增強拉曼光譜(SERS)的敏感度大幅提高，因此可以作為生物感測器的應用。
本篇論文分成三個研究主題。分別為研究利用微波合成的方法製備銀奈米棒/線的技術，以及探討加入核種後調整不同參數對成長銀奈米棒的影響，以及結合光學微影的技術對銀奈米材料做選區成長。
在微波合成銀奈米粒子的部份，在研究中已經證實微波加熱技術(Microwave heating technology)為一種高效率合成的技術，可以成功的應用在奈米合成方面，在實驗中，不需要藉由任何模版或是高分子聚合物當作包覆劑的輔助，藉由調整不同的加熱溫度以及反應升溫速率，證實可製備出純度高的銀奈米棒以銀奈米線。
在利用核種(Seeding growth)加入的部份，本實驗證實，利用核種的加入配合微波熱的技術，能夠在短時間且低溫的環境下合成出銀奈米棒，調整不同的參數，可以控制不同銀奈米棒的長寬比。
在結合微影技術製作選區成長的研究部份。本實驗成功的研究出利用光學微影(Optical lithography)的技術結合微波加熱的方法，能夠快速且完整的直接在設計好圖形的矽晶圓基材上製作出選區成長的圖形。此方法將能有效應用在不同的設計圖形上；製作在石英基板上，探討其不同的光學性質，或是應用在銀奈米粒子具有和蛋白質特殊的親和力，能夠在未來應用在生物晶片上。

Nanostructure materials has been interested in many areas of science and technology. This research range contains metal, non-metal, high polymer material, magnetic material, etc. The nanomaterials has many properties different from bulk materials, such as their low melting point, hardness, electric conduction.
Amount different elements of NPs, it is well known that silver NPs have properties superior to other nanostructured metal particles, such as their electrical conductivities, antimicrobial effects, optical properties, and applications in oxidative catalysis. For example, surface enhanced Raman scattering (SERS), which occurs on roughened metal NPs, is a powerful tool for microanalysis because it provides vibrational information on local areas and as such has potential for bio-sensing. The enhanced factor of SERS using silver NPs has been estimated experimentally to be 106–1015. It is expected that SERS is extraordinary sensitive to be a practical technique for the detection of single molecules.
There are three subjects in this research, including using microwave heating method for synthesis of silver nanorods/nanowires, adding to metal seed and control different parameter effect for silver nanorods, and combination with optical lithography for selective area growth of silver nanoparticles.
In the fabrication of silver nanoparticles, it was found that a feasible method for synthesizing silver nanorods/nanowires. A close chamber of a microwave system with precise temperature and control of different ramp is employed to synthesize the silver nanorods/nanowires, without templete or polymer capping agent existence.
Using seeding growth method for synthesizing of silver nanorods, it was found that using metal nanoparticles as a catalyst and combination with microwave heating method, adjusting different reaction time and catalyst volume, can synthesize silver nanorods with different aspect ratio.
In the combination optical lithography and microwave heating for selective area synthesize of silver nanoparticles, it was found that using this method, silver nanoparticles grew on pattern that we have been designed before so quickly. Using this method, we can extend to other pattern and other materials﹔fabricate on quartz, confer with different optical property, or with high affinity for the desired bio-functional molecules, have application for biosensor fabrication in the future.
