Gold nanoparticules: mechanism of formation, control of shape, size and internal structure

Since 2006, we developed methodologies for in situ kinetic studies on the formation of gold nanoparticles to attain the dynamic phenomenon in nanomaterials with an extraordinary time resolution (by taking benefit of 3rd generation synchrotron).  While several synthetic pathways for gold nanoparticles have been developped in the community, there is still a need for a better understanding of the mechanism of formation and development of complete characterizations methods. If size control is nowadays achieved, the control of the shape and internal structure still remains a difficult point.

For spherical nanoparticles, we evidenced the key role of the injection law of monomers. For anisotropic shapes obtained by seeded growth method, we evidenced the role of the initial structure of seeds and ratio of growth rate in different direction to control the final shape.  The originality of our approach comes from: (i) the acquisition of original data focusing on the occurrence of anisotropy (ii) a strong coupling between experiments and theoretical simulations.

Beyond the control over size and shape, the organisation and incorporation into an organic framework is indispensable to modulate the collective properties. We start to developp incorporation of nanoparticles into 2D organized diblock copolymers to go towards metamaterials.

Multifonctionnal microemulsions-reactivity in complex fluid

In the field of microemulsions, there is a huge interest to go towards multifunctional properties for new materials and new applications. The versatility of their structures (droplets to bicontinuous) and their high solubilization power can be merged with added properties coming from the use of a specific polar or apolar phases or from multifunctional surfactants.  We developed in our laboratory, a field of research on the relation between structure and reactivity in these new complex solutions. 

 

 Nanoprecipitation-nanodrugs

In the recent years, it has been proved that gathering in one molecule self-assembling properties with pharmaceutical function can enhanced the therapeutic activities. In the 2006’s, P. Couvreur (Université Chatenay-Malabry) has introduced the squalenoylation technology to develop new nanodrugs with improved efficiency (Couvreur et al, Nanoletter (2006, 6,2544)). In 2012, in collaboration with this team, we started to investigate the mechanism of formation of these particular nanodrugs obtained by the covalently link between different nucleoside analogues (known for their anticancer or antiviral properties) to the acyclic isoprenoid chain of squalene and formulated into nanoparticles trough nanoprecipitation processes. The final aim is the control in size distribution, internal structure and stability in biological media.

Dedicated to the particular case of nanodrugs, this research activity deals with the famous “ouzo” region and “surfactant free” microemulsion.   

Recently, in the framework of the project "Nanoprotection" (Labex NanoSaclay, flagship 2), we start a study on the structure and the future of the nanoparticles of Squalene-adenosine ( SqAd) in biological environment. NEW!

Reactivity in emulsion

 

Emulsion precipitation can be implemented on a large scale through the use of pulse columns which disperse large quantities of aqueous phase in the form of droplets in an organic phase. Precipitation occurs after coalescence of two drops each containing two different reactants. If the feasibility of such a process is now proved (use in the field of nuclear waste treatment), partial knowledge of the reaction mechanism is a limiting step. We propose in this project to study this process by using controlled systems. This project is supported by a collaboration between two CEA laboratories:  the SA2I in Marcoule ( contact Sophie Charton) and the LIONS in Saclay (contacts : Antoine Thill and Fabienne Testard).

Beyond studies on the coalescence between reactive droplets, we investigate the feeding of reactant through the organic continuous phase.  Fisrt studies focuses on grafted imogolites with the phD ( EDI, Univ. Paris Saclay) of Tobias Lange (start in Oct. 2016) NEW!

 Liquid/liquid extraction

 

Multifonctionnal microemulsions have been largely used in the field of liquid/liquid extraction where extractant can play the dual role of surfactant and chelating agent.  The so-called organic phase can be described as a microemulsion with chelating properties able to extract selectively some ions from an aqueous phase. In collaboration with CEA/DEN and CEA/ICSM, the structure of these particular extractant organic phases has been studied and rationalized through the properties of the curvature of the interfacial film between polar and apolar phases.  Beyond the relation between structure and extraction efficiency, recent development in the understanding of synergism for a combination of extractants have been obtained.  We also demonstrate the feasibility of kinetic measurement across the oil/water interface by the use of microfluidic chips.

Solid microemulsion - long chain fatty acid

Going towards solid microemulsion is very promising to keep bicontinuous structure and high specific surface within a solid material.  Recently, with D. Carriere (CEA/LIONS), we take advantage of the solvosurfactant property of long chain fatty acid above their melting point to investigate the formation of microemulsions with a ternary system water/ cationic surfactant (cetyltrimethyl ammonium bromide) and myristic acid.  The existence of a frustrated microemulsion driven by the association of fatty acid with CTAB was demonstrated, while temperature driven solidification fails by the segregation of the MA-CTAB surfactant film from liquid MA. Initially developed for materials with proton conducting, such approach with fatty acid solvosurfactant reveals an original behavior with promising towards new formulations.

Functionnalised surfactants for extraction or catalysis:

In collaboration with UVSQ (Ch. Larpent, Institut Lavoisier, UVSQ), new thermoresponsive chelating surfactants were developed with high promising towards new solvent free separation processes. A real molecular economy was demonstrated in cloud point extraction of uranyl nitrate in comparison to classical liquid-liquid extraction or classical cloud point extraction only based on solubilisation properties. This class of functional surfactants with organocatalyst functions is also powerfull to catalyse organic reactions in aqueous phases.
