 LIONS (Interdisciplinary Laboratory on Nanoscale and Supramolecular Organization) activities focus on the understanding and utilization of self-assembly for creating supramolecular architectures. The LIONS approach is truly interdisciplinary since it blends statistical physics, experimental physics both in the laboratory (microscopy, scattering, spectroscopy) and on large facilities (neutron scattering, synchrotron sources), chemistry (synthesis, elemental analysis) and biological inspiration. The paramount importance of interfaces in self-assembly means that a lot of effort is devoted to explain the effect of ions at interfaces, how interfaces can be modified between oil and water (stimulable emulsions, microemulsions) or how chemical reactions can transfer species through a liquid-liquid interface (with the help of many microfluidics devices). Elemental bricks for self-assembly are very often nano-objects of various shapes (spheres, tubes or rods) whose nucleation and growth is precisely controled by surface chemistry and kinetically analyzed by time-resolved scattering techniques and statistical physics tools. For some nanoparticles, LIONS has also gained a valuable expertise on their toxicity. At a larger scale, the self-assembly of nanometric bricks is studied for providing nanoparticle networks, supramolecular ligands for membrane attachment, polymer membranes or bio-inspired materials like in studies about biomineralization. LIONS activities are pursued through numerous french and international collaborations (USA, Spain, Italy, Germany, Greece, Israël).

Nanostructures et biomolécules : biomédecine et nanotoxicité / Nanostructures and biomolecules: biomedicine and nanotoxicity

Du fait de leur taille, les nanoparticules peuvent interagir avec les éléments du vivant, de la cellule à la molécule biologique. Ceci peut être mis à profit en médecine pour cibler des traitements, mais peut aussi présenter des effets indésirables, lors d'une forte exposition.

Le développement des nanotechnologies s'appuie de plus en plus sur la logique d'assemblage spontané (auto-assemblage) ou non, des briques élémentaires que sont les nanoparticules.

Interfaces, fluides complexes et microfluidique

Selon le domaine (énergies bas carbone, nanosciences pour les technologies de l'information et de la santé (RF-TIS), interaction rayonnement-matière) plusieurs équipes de l'IRAMIS sont impliquées sur cette thématique.

X-rays are used to investigate the structural properties of solids, liquids or gels. Photons interact with electrons, and provide information about the fluctuations of electronic densities in heterogeneous matter. A typical experimental set-up is shown on Figure : a monochromatic beam of incident wave vector is selected and falls on the sample. The scattered intensity is collected as a function of the so-called scattering angle 2 teta.

Control command system for experiments with TANGO
Laboratory experiments are increasingly composed of electronic hardware and computer controlled. In most cases the quality of the equipment (mechanical, electronics) is very good but the software is inadequate and not very flexible to the needs of researchers. LIONS chose to use the open source control system  TANGO developed by a collaboration of European synchrotrons ans scientific institutes (ESRF, SOLEIL...).

Mass spectrometry is an instrumental technique of analysis resting on the separation, identification and quantification of the components of a sample according to their mass. Thus atoms, molecules or aggragates are extracted in the form of ions, then sorted by a dispersive system: sector of electric or magnetic field, quadripolar filter or time of flight.

Rayons X
Les rayons X, rayonnement électromagnétique au delà de l'ultra-violet lointain, couvrent une gamme de longueur d'onde autour du dixième de nanomètre. Cette distance est de l'ordre de la distance entre atomes dans la matière condensée. Ainsi les rayons X peuvent interagir avec ces atomes (diffraction) ou les électrons (diffusion).

Molybdenum Wide Angle X-Ray Scattering (WAXS)

Workshop SAXS en laboratoire 2012

x-rays, electromagnetic radiation beyond the remote ultraviolet ray, cover a range wavelength around the tenth of nanometer. This distance is about the distance between atoms in the condensed matter. The diffraction of x-rays thus makes it possible to probe the matter, and to obtain information on the structure, the order and the composition of materials.
