Psychoactive molecules are essential tools for treating CNS disorders and exploring nervous system function. However, the lack of accurate in vivo tests has limited the discovery of novel psychoactive drugs over the last decades.
The platform, an automated motility recording system adapted for zebrafish embryos, allows the identification of in vivo novel psychoactive molecules.
It is based on high-intensity light stimulus which elicits a stereotypical series of motor behaviours in zebrafish embryos, the photomotor response (PMR). Interestingly, diverse classes of psychoactive molecules induce distinct, quantifiable and highly reproducible modifications of the PMR. PMR analysis can therefore be used to classify psychoactive drugs according to their activity.

Most of the formulated products are obtained by an optimal mixing of several components. Flow properties for fluids or viscoelastic properties for pasty materials are then essential for their final conditions of use (e.g. applying a paint on a solid surface or a cosmetic product on the skin under shear) or for the development of stimulated materials by change of pH, temperature, electrical or magnetic field, UV radiation, etc. These properties are connected to physicochemical properties of raw materials and final products. It is therefore essential for producers to have good knowledge of these physicochemical properties in order to achieve the best formulation and process of production.

PLATEFORME ÎLOTS DE CHALEUR
L’analyse et la caractérisation thermo-climatique de matériaux est une problématique constante notamment pour les structures en milieu urbain. La plupart des méthodes existantes pour mener ces études sont des techniques d’analyse d’échantillons à une seule couche, de grande taille (échantillons de quelques mètres carrés) et en milieu extérieur, ce qui est assez restrictif pour mener de nouvelles études. De plus, elles ne permettent de suivre que l’évolution des températures de surface des matériaux.
Face à l’absence d’une approche expérimentale globale des revêtements multicouches, la plateforme dispose d’une invention technologique apportant une solution à cette problématique. Le dispositif expérimental créé consiste en une enceinte climatique permettant d’étudier le comportement thermique et climatique de matériaux multicouches soumis à un protocole climatique donné. Un avantage supplémentaire de cette invention est sa capacité à tenir compte des interactions entre les différentes couches qui constituent les matériaux urbains. L’autre particularité du dispositif est la possibilité d’injecter à intervalle de temps souhaité une quantité d’eau en surface en vue d’étudier l’impact de l’évaporation d’un film d’eau en surface. Une cloche en plexiglas vient se positionner à la surface du revêtement et un capteur mesure la teneur en vapeur d’eau évaporée.

ELECTROCHEMICAL ATOMIC FORCE MICROSCOPY PLATFORM
The research group proposes a high resolution electrochemical imaging platform for in situ functional probing of individual redox or redox labeled nano-objects (nanoparticles, (bio)-macromolecules, viral particles…) immobilized on a surface. For this, the group has developed an original imaging technology coupling atomic force (AFM) and electrochemical (SECM) microscopies and enabling the simultaneous acquisition of topographic and electrochemical images with a nanometer resolution. This coupling is made possible by the use of metal nanoprobes (nanoelectrodes) produced by the group following an original process. AFM-SECM microscopy thus offers the possibility of correlating different properties (topographic, redox or catalytic) measured for the same individual nano-object. It is free of the limitations of other nano-characterization imaging techniques such as XRD, TEM and AFM which are either ex-situ, nonspecific and/or purely topographic methods. Development of AFM-SECM is therefore an important technological leap toward functional analysis of nano-objets at the macromolecular scale.
We offer, via collaborative mid or long term research contracts (3 months min.), to design experimental strategies allowing AFM-SECM correlative imaging of redox (bio)-nanostructures immobilized on a surface, in the framework of (bio)-nanotechnology applications.
Scientific expertise :
- High resolution correlative imaging of single redox nano-objects
- Fabrication of metallic (functionalizable) combined nanoelectrode - AFM probes
- Redox labelling of nano-objects (nanoparticles, viruses, proteins, etc.)
