The range project aims to strengthen the network of nanotechnology platforms in the Greater East region, to better coordinate the research work carried out by the teams (Universities of Strasbourg, Reims-Champagne-Ardenne, UTT and Lorraine, CNRS), to pool know-how and results so that stakeholders can move their respective themes faster. The teams directly involved in the range project represent a potential of about 100 researchers, PhD students and post-doctoral students. The project focuses on new innovative developments in the fields of nanostructures for optics, biosensors and nanoelectronics, both anticipated and with high scientific potential and impact. In this context, this project aims to develop an original method of electrochemistry in ionic liquid media, through the synthesis and implementation of silicon nanostructures. Compared to the state of the art, the proposed methodology aims in particular to increase the efficiency of systems and costs. Using the technological means of the Nano'Mat platform and the development skills of the LRN, the project proposes a real technological break with current synthesis methods. The development of growth and nanostructuring technology will be extended by the development of highly sensitive selective gas sensors by the other members of the consortium of the range project.
