The paper introduces a new class of materials with azo-polysiloxanic structure bearing the property to generate nano-structured surfaces by laser irradiation. The ability to modulate the optical response of the film, through a modification of the polymer chemical structure, has been investigated. The azo-materials were tested for their ability to support cell adhesion and growth, with very promising results. A future use of these materials as growth support in cell cultures is of great interest, due to an easy, one step-method to generate the surface relief grating and to the possibility to introduce a large range of chemical modifications due to the presence of the chlorobenzyl groups in the polymeric side-chain.
