LAUREA MAGISTRALEThe areas of application of 2PP technique described in this thesis are related to the great field of optoelectronics, specifically to an alternative technology for “e-paper” or “e-ink”, and focuses on the study of the nematic liquid crystal 5 CB behavior in 3D woodpile-like structures at the application of transverse and longitudinal electrical field. The second area deals with a microfluidic applications in Lab-on-a-Chip devices, and focuses on the study of microstructures in SZ2080 optimized for filtering in microfluidic channels
