    Abstract: 革蘭氏陰性菌為環境中常見的菌種，牠們通常透過食物和飲水汙染引起一連串的疾病和感染。本研究主要透過掃描式電子顯微鏡和穿透式電子顯微鏡等物分析儀器探討奈米銀離對大腸桿菌(E.coli)抗菌特性的影響，並依據Z2801:2010的標準進行抗菌試驗，實驗結果顯示在細菌的懸浮液中有相對大量的銀離子釋出，並對大腸桿菌具有優秀的抗菌能力，其抗菌率高達100%，因而，銀離子對大腸桿菌生物膜的形成也同樣具有抗黏附性。

    The Gram negative bacteria are commonly bacteria in the environment. They often resulting in environmental, food and drinking water contamination and then causing some serious diseases, complications and infections. This study is to investigate the influence of nano siliver ion on antibacterial properties against Escherichia coli (E.coli) cells by means of scanning electron microscopy and transmission electron microscopy. A standard experimental procedure JIS Z2801:2010 specification was performed in this antibacterial test. The experimental results indicated that as the bacteria suspension with trace amount of nano silver ion exhibited an excellent antibacterial property against E.coli. It has an antibacterial rate nearly of 100%. Furthermore; bacterial biofilm formation assay results also found that silver ion can strongly inhibit E.coli to adhesion on the surface of devices.
