Résumé

The aim of my project is to develop a low-cost bottom-up based lab-on-a-chip nanofluidic device for biomedical or analysis applications. Common researches try to create such kind of devices by realizing high-cost top-down (ebeam lithography in example) nanochannels. In this thesis much cheaper bottom-up nanoporous materials are analyzed. Fundamental aspects of nanofluidics have to be studied in these materials in order to fully exploit their potentiality. A final step of coupling with microfluidic channels is performed in order to allow connecting this device with previously studied microfluidic circuitry. Capillarity and electro-osmosis in these materials are studied and analyzed as the driving forces for separations in the device both experimentally and computationally. The diffusion of species (without and with an electric field) is studied experimentally and then simulated through Stochastic Rotation Dynamics.
