Le Mans Molecules and Materials Institute
Tools for Restorative and Regenerative Medicine

Organization activities


Le Mans Molecules and Materials Institute is a research unit depending on “CNRS” and “Université du Maine” institutions.


The IMMM comprises 72 researchers and a technical and administrative staff of 32 persons, 55 PhD students, about 30 Master students and about 10 post-doctoral or invited professor positions.


Research activities rely on well-established knowhow and renowned expertise in chemistry, physicochemistry and physics and are organized in 4 topics: organic material, inorganic material, physics of confined systems and polymers. A wide range of applications are targeted such as bioactive molecules, materials for the sector of energy, of environment and sustainable development, of health, of agrifood, plastics industry and soft materials, and of optics.


State of the art equipments are available in the IMMM institute: for diffraction, microscopy, spectroscopy, radiation delivery, rheology, plasma, combined with innovative technics (super-fast spectroscopy, probes, pumps, impulsive lasers).

This facility allows multiple and multi scale characterization of innovative materials and functional nano structures, complex fluids and surfaces, associated to an expertise in expertise spectrum processing and numerical modelling.


The IMMM is funded by classical French subsidies and grant but also get fuds from multiple industrial collaborations. In addition, the IMMM institute is proactive in European and international projects.


The IMMM is organized in 4 research groups:

  1. Polymers
  2. Organic synthesis
  3. Inorganic materials
  4. Physics of confined systems

Groups 1 et 2 are currently linked to Bioregate projects.


IMMM research activities linked to Bioregate topics


The research group gathers chemists, physico-chemists and des physicists to prepare polymeric materials with interesting features for their volume, surface or interface. These basic researches brings solutions to needs expressed in health, energy, transportation or environment sectors.


We work on:

  •  Functional polymer preparation
  • Controlled autoassembly
  • Polymers interfaces

Organic synthesis

We are particularly interested in:

  • Reactions of homo- and heterocycloadditions
  • Reactivity of polar organometallic components
  • Use of titanacyclopropanes in the framework of synthesis
  • Synthesis and assessment of original (organo)catalysts coming from the biomass


These basic researches lead to bioactive components and some are used for example in the field of cancerology or immune system modulation.
