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.
