Main research topics

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 (...)

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 (...)

Development of capacitive nanoparticle-based strain sensors

To deploy networks of connected sensors at large scale in embedded systems, it is mandatory to use wireless sensors with low power consumption. Helped by his strong knowledge and experience with resistive nanoparticle-based strain sensors, the Nanotech team studied the fabrication of capacitive (...)

Directed assembly of colloidal nanoparticles on surfaces

The Nanotech team develops multiple complementary approaches for the directed assembly of colloidal nanoparticles onto rigid or flexible surfaces. *Convective Self Assembly The convective self assembly (CSA) technique makes use of the hydrodynamic and capillary forces that appear at the (...)

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 (...)

New generations of resealable and multifunctions microfluidic chips

The main goal is to realize the first step of the nanoxerography protocol (contact between the colloidal dispersion and the charged substrate) not anymore by simple immersion in the colloidal bath but via the automatized injection of the dispersion inside a microfluidic chip. The development of (...)
