Particle image analysis: A new tool for the exploration of nanofluidic flows

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

In this paper, we expose the developpment of a new method for local characterization of nanoflows based on imaging of nanoparticles by Total Internal Reflection Fluorescence (TIRF). We reconstructed concentration and speed profiles with unprecedent accuracy by the use of this method. This has allowed the measurement of the slip length and of the Debye length in a water flow above a glass surface. Our new tool is thus a powerful method for the investigation of the nanofluidic world and open new perspectives for the fundamental understanding of nanoflows and for the further design of nanofluidic devices.
