reate nano-structured materials that would allow a better development of human cells.

The Polish partner in the team, the Military University of Technology of Warsaw, has been in charge of the development of the new laser-based technology called EUV (Extreme Ultra-Violet) that was used for the creation of the nano-structured polymer surfaces. A beam of EUV light formed with a unique mirror developed by the Czech partner REFLEX S.R.O is directed on the surface allowing the creation of new kinds of polymeric materials. This innovative technique allows for a very high degree of precision, from 10 to 20 nanometres, whereas conventional techniques allowed only for a maximal precision level of 100 nanometres. 'One of the newest theories in the field of cell growing is that the smaller the structure, the wider the possibilities to manipulate cells,' says Professor Heitz.

A wide range of human cells

The EUV technique, thanks to its particular level of precision, also allows for the conservation of the material's structure, which was not the case with other methods used to modify the polymer. 'A regular structure is essential if the material is to be used for the purpose of growing human cells,' says Dr Henryk Fiederowicz, Professor at the Military University of Technology.

The story does not end there. Nano-structures built through the EUV technique have the ability to influence the behaviour of organic cells and different kind of cells can be grown better and faster depending on the type of polymer surface used.

The variety of material used to grow human stem cells will determinate the way cells will differentiate, meaning that they will transform into another human cell type. In other words: 'Using one type of polymer material or another will help you grow different types of muscle, nerves, cells adapted to a human heart, bone or any other part of the human body,' says Professor Heitz.

Thanks to their affinity
