Abstract
In the last teen years LbL (Layer-by-Layer) method was frequently used in basic scientific research of polyelectrolyte structures. In our postdoctoral project we want to continue and develop scientific and research work that we started in collaboration at Department of Physics University of Maribor with research group of Max-Planck Institute for Colloids and Interfaces in Golm, Germany and research group of Institute for Medical Physics and Biophysics, University of Leipzig, Germany. The LbL method is aimed to be applied to research of physical and chemical properties of new materials for target delivery systems developed for an application in medicine and chemical, pharmacological and food industry. Furthermore, the research of nano and microsensor with respect to different physical and chemical parameters will be continued as well. Research group at Faculty of Chemistry and Chemical Engineering has been collaborating among others also with a lot of scientific groups around the world. Between them there is also a group from University of Bochum, Germany. In collaboration a method for formation multifunctional composites like nano and micorparticles was developed. Particles with controlled physical and chemical properties can be fabricated by a controlled fast expansion method of supercritical fluids. Then, these monodisperse spherical particles will be used as template for developing polyelectrolyte capsules. With incubation of polyelectrolyte nano and microcapsules in supercritical fluids we will influence on interactions among polyelectrolytes in capsules wall. Research of stability and adhering of nano and microcapsules and coated particles in supercritical fluids will contribute to understanding basic physical and chemical interactions among polyelectrolytes in capsule wall and its application in medicine, pharmacology and food industry.
Significance for science
Polyelectrolyte capsules present a new type of materials. Modification of polyelectrolyte capsules in supercritical fluids opens a way for scientific research in investigation of polyelectrolyte capsules properties in dependence of system parameters. With these results we will contribute to deeper understanding of interactions among polyelectrolyte layers as well as among polyelectrolyte in these layers.
Significance for the country
Research project proposed will contribute to general progress in chemical and physical as well as biophysical sciences in Slovenia. These are actual fields of interdisciplinary bio and nano technology and science.
