Top down and bottom up approach to self-assemble functional porous films

A double simultaneous approach has been used in this doctorate work in order to obtain complex multi-functional porous materials which can fi nd application in bio-senors and lab-on-a-chip devices. On one side a method to achieve an increase in the biological analyte detection within the mesoporous fi lms has been studied through the application of deep x-ray lithography. This technique causes multiple effects on the fi lm allowing to easily obtain the final desired structure. On the other hand, wider pores than mesopores are required for the use of thin films as a host for biological species, both due to the size requirement and for the easier pores accessibility by mean of larger pores. The possibility to tune important parameters such as pore size and shape and pore accessibility or selectivity has been achieved in this work thus giving rise to multi-functional macro-mesoporous materials in form of thin films.
