The Center of Micro & Nano-Rheometry is a technological platform of the Institute of Physics of Nice (InPhyNi) of the University of Nice-Sophia Antipolis. The Center is accessible to companies or external laboratories under research contracts or services. The center's equipment is essentially dedicated to the physico-chemical characterization of materials based on micro or nanoparticles: Measurements of viscoelastic properties of materials: forces (AFM, Viscoanalyseur) or couples (rotational rheometers) at macro, micro and nanometric scales. micro- and nanoparticles (size distribution, charge, zeta potential, etc.) and the composition of complex fluids (TOC, UV spectrometer, ICP).
