URCA's NANOMAT platform has the following tools:
The particular expertise of the platform primarily focuses on the use and development of near-field microscopes (in particular atomic force microscopy) and electron microscopes.
The platform expertise not only focuses on the usual use of these microscopes but also on original instrumental and methodological developments that make it possible to have specific and unique nanocharacterisation tools.
In terms of the specifics of the experiments developed and available, even though all types of samples can be studied, we have nevertheless specifically developed the techniques for preparing samples and methodologies for studying polymers (organic, plant, etc.) and living organisms (cells, membranes, etc.) for applications in the field of Health/Biology and Agricultural resources/agromaterials. In addition to high-resolution imaging, our area of expertise is also in the local analysis and mapping of mechanical (adhesive force between biomolecules through the functionalisation of tips, mechanical properties of healthy or tumour cells, mechanical properties of agromaterials and biosourced materials, polymer materials for mechanical reinforcement, etc.), chemical (nanoInfrared, molecular recognition), optical (near-field cathodoluminescence, fluorescence techniques), electric (KPFM, nanoEBIC) and thermal (SThM) properties.
These different analyses can be done in any type of conditions (temperature control, variable pressure, vacuum, humid controlled atmosphere, very high-speed imaging), whether with electron microscopy or near-field microscopy.
Among all the techniques developed, we can point to some particularly original ones at international level which have benefited from specific developments.
The University of Technology in Troyes and the University of Reims Champagne Ardenne have pooled their equipment and skills on a twin-site (Troyes/UTT and Reims/URCA) Nanomanufacturing and Nanocharacterisation platform dedicated to materials for optics, mechanics, biology and agricultural resources. In Reims in particular the platform specialises in high-resolution imaging and nanocharacterisation of all types of materials, ranging from metallic materials to plants and living cells.
Thanks to the various microscopes present on Nano'Mat (optical, electron and near-field microscopes) and the associated original characterisation tools (chemical analysis, cathodoluminescence, near-field electron, nanomechanics, etc.), it is possible to do multiscale imaging (from nm to several hundred microns) in different work environments (vacuum, controlled atmosphere, controlled temperature). The traditional imaging functions are combined with chemical analysis experiments and analysis of optical, electrical, mechanical and thermal properties which make it possible to get a high resolution to map properties.
The services offered therefore mainly concern nanocharacterisation techniques which make it possible to do high-resolution imaging but also study the specific properties at a local level.
Service offer to companies: no service, but partner research and training activities through research in various forms (engineering internships in the 4th or 5th year of higher education, doctoral thesis, post-doctoral contract, etc.)
Equipment open to non-institutional researchers in the form of either a research partnership or through a contribution to training and operating costs.
