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.
