Résumé

This paper presents the realization of a hydrodynamic microfluidic trap with the goal of sorting MEMS for self-assembly experiments in liquid. A simplified analytical design rule has been compiled and numerically verified. Microfluidic devices have been fabricated in PDMS and PMMA beads have been trapped in a controlled way, validating the concept.

Self-assembly of nanoparticles

Nanoparticles are classified as having at least one of three dimensions be in the range of 1-100 nm. The small size of nanoparticles allows them to have unique characteristics which may not be possible on the macro-scale. Self-assembly is the spontaneous organization of smaller subunits to form larger, well-organized patterns. For nanoparticles, this spontaneous assembly is a consequence of interactions between the particles aimed at achieving a thermodynamic equilibrium and reducing the system’s free energy.

Droplet-based microfluidics

Droplet-based microfluidics manipulate discrete volumes of fluids in immiscible phases with low Reynolds number and laminar flow regimes. Interest in droplet-based microfluidics systems has been growing substantially in past decades. Microdroplets offer the feasibility of handling miniature volumes (μl to fl) of fluids conveniently, provide better mixing, encapsulation, sorting, sensing and are suitable for high throughput experiments.

Auto-assemblage

L’auto-assemblage, parfois rapproché de l'auto-organisation, désigne les procédés par lesquels un système désorganisé de composants élémentaires s'assemble et s'organise de façon spontanée et autonome, à la suite d'interactions spécifiques et locales entre ces composants. On parle d'auto-assemblage moléculaire lorsque les composants en question sont des molécules, mais l'auto-assemblage s'observe à différentes échelles, des molécules à la formation du système solaire et des galaxies en passant par l'échelle nanométrique.
