Spontaneous and dense assemblies of nanoparticles within micro-channels by the bubble deposition method

We explore the potential of the bubble deposition method (BDM) for the specific monolayer organization of spherical and anisotropic NPs onto microstructured surfaces. These structurations cannot be only explained by the classical interactions between nano-objects and substrates but mainly by a combination of the drying front peculiar to the BDM with lithographically patterned substrates. Extended up to the integration of SWNT, this approach represents a simple, efficient, nano-object independent and potentially useful route for nanometric device realization.
