Streszczenie:
We stated developing the model the self assembly of cellulose microfibrils in silicon considering both allomorphs I-alpha and I-beta. The modelling has been benefited by a crystallographic structure of CESA complex. In the experimental part we have extracted cellulose I microfibrils from plant source and obtained bacteria nanocelulose for comparison in AFM studies with an aspect ratio of d=5-10 nm. We have design a theoretical framework for the analysis of mechanical properties of biological systems (e.g. proteins, lipids and polysaccharides). The robustness of this protocol has been tested in several biological complex systems (Protein membranes). In addition, we develop a simplified model of proteins using coarse grained technique via the so called Elastic Network (EN) model. It has yield a model for the study of protein-cellulose system. Part of this work has been already published.
