EPFL/IMT - Peking University workshop on MEMS and related technologies
Nanofluidics is a booming research topic which studies ion transportation in nanometer sized confined space. However, real application of nanofluidics faces serious challenges from difficulty in surface modification, complexity and costliness in manufacture. We have developed a novel nanofluidics scheme, named as nanofluidic crystal, to address the above issues by using nanoparticle crystal (NPC) as the basic functional nanostructure. Nanofluidic crystal is an ease-in-surface-modification, simple and cheap approach to establish a nanofluidic system, and thereby can be used to construct various biosensing devices. Here, we theoretically analyzed the electrokinetics properties of the nanofluidic crystal and developed a simple electrical model for device design and optimization. Preliminary applications of nanofluidics crystal in protein and metal ion sensing have been demonstrated.
