Nano-Sensor - Nanotechnological Engineering


This project begins with a bibliographic work in the framework of sensors and an oral presentation of this work.

It follows with an experimental work et a report on the experiments.


The experimental realization of a sensors includes:

- chemical synthesis of nanoparticles; characterization by dynamic light scattering (DLS), electron microscopy, atomic force microscopy (AFM);

- Assembly of the nanoparticles by convective deposition, nanoxerography, and/or dielectrophoresis;

- Electrical measurements of the nanoparticles based sensors; characterization of gas sensors under pcontrroled partial pressure of different gas; study of the temperature effect; sensibility and selectivity.







The projects are realized by groups of 2 or 3 students. The whole project (bibliographic + experimental) corresponds to about 60h. 30h are in presence of the professors, 20h of which are dedicated to the experimental works.


At the end of this module, the student will have understood and be able to explain (main concepts):


- the approach and the different steps for the conception and realization of a micro- and nano-electronic by integration of nano-objects synthesized as a colloidal solution;

- the operating model of a nano-sensor


the student will have understood and be able to explain:

- the main concepts and the experimental practices about nano-object synthesis and stabilization of colloidal solutions;

- the main concepts and the experimental practices about deposition of nano-objects from a solution into 2D and 3D arrays on a surface;

- the physical principles of nanoparticles based sensors (gaz sensor, strain sensor …).



The student will be able to:

- produce a sensor relying on nanoparticle arrays with particles synthesized and assembled during the project;

- measure the sensor properties and describe how it works;

-discuss the results obtained and suggest improvements..


The student will be able to:

- suggest a reasonable solution for the realization of a sensor gathering the different concepts described above;

- produce an expertise on the conception and the practical realization on a novel sensor.

Needed prerequisite

Master 1 in Physics, Applied Physics, Chemistry or Material Science or equivalent

Form of assessment

The evaluation of outcome prior learning is made as a continuous training during the semester. According ot the teaching, the assessment will be different: as a written exam, an oral exam, a record, a written report, peers review...
