摘要

為了突破繞射極限，先前文獻將單顆微米球放置於量測物表面，配合奈米噴流技術可以看到高分辨率的奈米成像，但因單顆微米球成像的區域太小，所以為了擴大成像區域需要大面積二維微米球陣列，但由於目前沒有可形成完美大面積二維微米球陣列的排列方法。因此本文提出一種新穎的自我組裝方法，成功排列出1cmx1cm單層二維結構，並通過降低排列基板的摩擦力、不同濃度之乙二醇加水的微米球懸浮溶液、不同的揮發溫度及懸浮液微米球濃度來調控6um微米球的排列，實驗結果使用俱潤滑的石墨基板，乙二醇與水的重量濃度為9:1，揮發溫度為100℃及5x〖10〗^(-6)wt%微米球懸浮液時，可以得到最佳的微米球排列及降低雙層微米球排列的機會。

In order to overcome the diffraction limit, according to a method of previous research[4] is to put the single microspheres on the measuring surface so that we can see nanometer high resolution imaging by nano-jet technology. We have to expand the imaging region into large two-dimensional microspheres array because the single microsphere imaging region is too small, and there is no arrangement method can be formed perfect large area with-two-dimensional microsphere array now. Therefore, this studies proposes a novel self-assembling method, successfully arranged a 1cmx1cm single layer two-dimensional structure by reducing the friction of the arrangement substrate, microspheres suspended of the ethylene glycol add water solution of different concentrations, different volatilization temperature and microsphere suspension concentration to control 6μm microspheres arrangement. The results of using with lubricating graphite substrate, weight concentration of ethylene glycol and water is 9:1, volatilization temperature at 100℃ and 5x〖10〗^(-6) wt% microsphere suspension, can get the best microspheres arrangement and reduce the chance of double layer microspheres arrangement.
