Cellulose and modified cellulose based materials for bioapplications
Cellulose is the most abundant polymer on Earth and as a biopolymer it is a good candidate for application in tissue engineering. In plants and bacteria cellulose is produced at the interface of the environment and the cell membrane and it forms the extracellular matrix. The structure of cellulose can be therefore used for cell culturing in an environment that is similar to their natural state. The disadvantage of cellulose for tissue engineering is its non-degradability. Cellulose derivates or nanocellulose loaded with enzymes promoting its controlled hydrolysis expand application of cellulose inside the human body where the implanted tissue carrier dissolves after a new tissue is created. This work is aimed on preparation and characterisation of modified cellulose and nanocellulose materials for tissue engineering application.

Immobilization of metal nanostructures on polymer carriers
Experimental work aimed at preparation of metal nanostructures and development of methods of their immobilization on polymer carriers for the next generation of antimicrobial surfaces. Both physical and chemical methods of nanostructures immobilization will be emploied, based on interaction of prepared nanostructures with laser light or chemical agents. Antibacterial effects and biocompatibility of developed surfaces will be evaluated in cooperation with the Department of biochemistry and microbiology UCT Prague.
Intelligent materials and surfaces - switching between "ultra" states
Materials for quantum memories and computers
Modification of polymers by metal nanostructures
The work consists in the preparation of composite materials based on polymers and metal nanostructures for use in biological applications, exploiting their antibacterial effect. Polymeric carriers will be deposited by metal layers which will be nanostructured by the action of a power excimer laser. Alternatively, the possibility of replicating metallic nanostructures from inorganic carriers (silica, silicon) into biocompatible polymers will be studied.
Plasmon catalysis - a new trend in chemical transformations
Preparation and characterization of nanostructures with specific magnetic properties
Pulsed laser deposition and surface modification by high energy excimer beam
Preparation of laser deposited/exposed special materials (biopolymers, metals, special carbon materials) in order to prepare homogeneously nanostructured surfaces. Optimization of deposition / exposure time to prepare structures with unique physicochemical properties or "new types" of structures (graphene, Q-carbon). Specific polymer composites (carbon nanowires and nanotubes in polymer) will also be prepared and their response to high energy laser excimer beam exposure will be monitored. Changes in surface properties of bulk modified materials, especially changes in conductivity, surface morphology, roughness and surface chemistry will be studied. The modification will be carried out with the aim of precise control of the types of prepared structures (dot, line, wrinkled nanopattern). Interdisciplinary character of the work - possible applications in chemistry, electronics and biocompatibility studies (tissue engineering).
