Abstract

---

Azo-polymers are part of the “intelligent materials family” because they are able to change the configuration, elasticity, or other mechanical parameters using only the light as an external stimulus.

Using of a polarized laser source can generate surface relief gratings on the film surface used as cell culture support. Azobenzenes undergo an isomerization process, passing from the stable trans configuration, toward the less stable geometric isomer, cis. Large conformational changes are associated with the transcis photochemical isomerization of azobenzenes.

Understanding and manipulating these reordering phenomena at the molecular level is beneficial for the applications of azopolymers in the bio-field. Valuable information can be obtained through molecular modeling studies. Using this method we are trying to understand the mechanism that originates from the mass transport process which takes place in azobenzene materials.
