NADIS method

A liquid nanodispenser, called NADIS, was recently developed to answer the need of deposition techniques for nanosciences. The deposition is realized with an original atomic force microscope (AFM) tip including a nanochannel drilled at its apex by Focused Ion Beam. The liquid transfer is performed by capillarity through this channel during contact of the tip with the substrate. It was shown that, by tuning the tip properties, the size of the deposited patterns can be controlled down to 70 nm in diameter corresponding to volume in the attoliter range (10-18 L).

Nanoparticles deposition

Molecules, nanoparticles or proteins in solution could be patterned with high resolution. In the case of nanoparticles, we assessed the ultimate limit of the method and showed that large arrays of single (or pairs of) nanoparticles can be reproducibly deposited. It demonstrates that NADIS can be an alternative to other scanning probe lithography techniques since the versatility of liquid manipulation allows the high resolution direct writing of any soluble molecules or nano-object (nanoparticles or biomolecules).

Capillary force

 We also demonstrated that, in addition to its interest for surface patterning and molecule deposition, NADIS is a unique tool to probe capillarity and wetting at nanoscale as illustrated by studies of capillary forces, spreading dynamics and evaporation at sub-micron scale.
