Main research topics

Directed assembly of colloidal nanoparticles on surfaces

The Nanotech team develops two complementary techniques of directed assembly of colloidal nanoparticles on surfaces. * Convective self-assembly Convective self-assembly uses hydrodynamic and capillary forces present at the solid-liquid-gas triple line during the move of the evaporation front (...)

Development of nanoparticle-based resistive sensors

The Nanotech team develops resistive sensors such as strain gauges, humidity sensors and temperature sensors. They are based on compact nanoparticle assemblies made by convective self-assembly. Figures 5 and 6 illustrate some results obtained with nanoparticle-based strain gauges. These (...)

Transport measurements on silicon nanocrystals

During the European project NEON (2001-2003), CEMES and IMEL developed a method for the synthesis of a 2D silicon nanocrystals layer embedded in a thin insulating oxide layer obtained by ultra-low-energy ion implantation followed by oxidizing annealing. TEM cross section and SEM (...)

Directed assembly of biological objects on surfaces for their study with AFM

The Nanotech team also adapts its techniques of directed assembly of colloidal nanoparticles to the directed assembly of yeasts and bacteria. These works are made in close collaboration with the Nanobiosystems team from LAAS and aim at studying these biological objects by atomic force (...)

Plasmo-electronic: “plasmonic photoconductance in free-standing monolayered gold nanoparticle membranes”

Plasmo-electronic: “plasmonic photoconductance in free-standing monolayered gold nanoparticle membranes”. In collaboration with Adnen Mlayah (CEMES / CNRS, NeO team) (adnen.mlayah@cemes.fr), we develop the plasmo-electronics field, coupling between plasmonic phenomenon and electron transport of (...)

Nanomarkers

Based on the directed assembly technique of nanoxerography, the Nanotech team has developed secured marking stickers also called nanomarkers or nanotags. It is about reproducing via the electrostatic directed assembly of colloidal nanoparticles, a logo, a pattern or a code of desired geometry (...)
