在过去的几十年中，我们见证了制造粒径从几微米到几纳米的单分散系统的不同技术的发展。这些粒子的大小和形式不同，它们的化学结构可以是复杂的，也可以是简单的。在最初，这些系统的研究重点是寻找不同的物理和化学性质，这可以从粒子的大小和它们的形态强烈依赖。后来有人指出，它们用于制造具有特定和重复特性的材料。如今，科技和医学的微型化趋势特别加快了这一用途。它们使得在经济上在单分散胶体系统中传输制备安排的实验室技术方面取得了很大进展。讲师将重点讲解单分散胶体系统在樱桃和颜料制造、摄影、化学抛光，特别是在单分散药物制造中的作用。他将展示胶体颗粒如何在药物传播中发挥作用，从而对预先选定的人体部位产生延迟效应。它们也用于诊断，特别是在X光检查中。由于纳米分散体和微分散体的性质不同，它们的用途也不同。

| 课程简介: |
In the last decades we witnessed the development of different techniques for the manufacturing of monodispersed systems with particle size from few micrometers to few nanometers. These particles are of different sizes and forms, their chemical structure can be complex or simple. At the beginning the focus of research of these systems was in the search of different physical and chemical properties, which can be strongly dependent from the size of the particles and their morphology. Later on the interest was pointed towards their use in the making of materials with specific and repeated properties. This use is specially accelerated by today’s trends in miniaturizing in technology and medicine. They enable a large progress in the transmission of laboratory techniques of preparative arrangements in monodispersed colloid systems in the economy. The lecturer will focus on the role of monodispersive colloid systems in the manufacturing of cheramics and pigments, photography, chemical polishing, and especially in the making of monodispersive medicines. He will show how colloid particles are useful in the transmission of medicines with delayed effect on the in advance chosen part of the human body. They are also used in diagnostics, especially in x-ray examinations. Their use is different because of the differences in the properties of nano and micro dispersions.
