Doctoral School - recruitment

The aim of the project is a design and preparation of new biomaterials based on modified biopolymers. In the project several biopolymers (polysaccharides and proteins) will be used to prepare appropriate composite based on biopolymer blends. Dual crosslinking using physical and chemical methods will be used to optimize the materials properties. New biopolymer based materials will be studied as potential biomedical applications. Morphological and physico-chemical properties of new material will be modified in order to achieve good biological properties. The interaction with fibroblast and keratinocytes will be studied. Thermal and photochemical stability of the new materials obtained will be studied. Within the project mechanical properties, swelling, and biodegradation will be studied. Film forming properties of biopolymer blends will be studied for applications in hair care cosmetics.

For chemical study the following techniques will be used: FTIR-spectroscopy, UV-Vis spectrometry, XRD, SDS-Page electrophoresis, GPC chromatography, HPLC. The surface properties will be studied by AFM and SEM microscopy, apparatus for contact angle measurements. Moreover, mechanical and thermal properties of new materials will be studied. For the study of hair properties after applications of new materials the following instruments will be used: microscope, sebumeter, colorimeter, ARAMO TS for study the hair general look.

Biocompatibility of new materials prepared under this project will be studied by in vitro study.
