摘要註:	目前單分散膠體顆粒可以說備受關注，不僅在於它本身科學價值，在技術應用上也頗受青睞。然而可惜的是，通常在粒子製備過程中常常會涉及多種有毒化學品或溶劑的參與。因此近年來，有越來越多胺基酸被當作陰離子表面活性劑運用於奈米材料的合成。氨基酸為人體中一種必要的成分，因此在對於環境或人體是呈現無毒、無害。經由以上論點，所以本實驗在這選用胺基酸中的賴胺酸進行奈米粒子合成.本研究主要探討賴胺酸輔助奈米粒子的合成，與此類奈米粒子之組裝狀況。整體實驗過程複雜度低，沒有有機溶劑的添加而於純水相下進行，與目前流行的綠色化學相當符合。粒子合成結果分析主要藉由紫外光-可見光吸收光譜儀(UV-Vis Spectrometer)與掃描式電子顯微鏡(Scanning Electron Microscopy, SEM)。實驗中賴胺酸在粒子的合成扮演著相當重要的角色，因此分別對其濃度、溶液中pH值、環境溫度、轉速的變化來觀察合成粒子粒徑與密度..等的變化。根據本篇論文的研究結果，證實經由適當的還原方式與製程參數，可以使得奈米粒子合成具有低複雜性、無汙染、均勻的粒徑分佈與穩定性，具備實際應用的價值。 Monodispersed colloidal particles have attracted much attention not only for their scientific interest but also for many technological applications. However, many kinds of toxic chemicals or solvents are usually involved in the particle preparation process. Amino acid is an essential in the body so non-toxic and harmless to the environment or human. Recently, anionic surfactants derived from diverse amino acids have been applied to the synthesis of nanosized materials. These accomplishments have inspired us to use amino acids in preparing materials unique in structure. In this work, we used lysine to assist the synthesis of nanoparticles. The synthesis and the assembly property of nanoparticles were investigated. The experimental process of low complexity, and in pure water phase with no organic solvents participated, is consistent with the currently popular green chemistry. The resulting nanoparticles were characterized via UV-Vis Spectrometer, and Scanning Electron Microscopy. The critical roles of lysine in the formation of nanoparticles were investigated on the basis of experimental results. The influences of the concentration of lysine, solution pH value, temperature, and stirring speed on particle size and size distribution are discussed. By employing such an appropriate reduction method and process condition, we can make nanoparticles process simplification, non-polluting and has a good size distribution and stability, with the value on the practical application.
