OFFER DESCRIPTION

The candidate will develop new on-surface protocols for producing ultrathin 2D Au mesocrystals and perform all structural characterization and some nanofabrication steps in the ARCEN (ICB, Dijon) platform. The protein origami designed by our biochemist partners will be characterized by TEM and cryoEM in the CBI (Toulouse) facility and exploited as templates for the morphosynthesis of anisotropic Au/Ag crystals and the assembly with emitters. All structures and protein-metal interfaces will be characterized structurally (AFM, TEM) and optically (TIRF, Raman).

The proposed project will combine two concepts to produce and exploit macroscopic ultrathin 2D gold crystals with designable surface functionalization: (1) new on-surface synthesis protocols and (2) design and characterization of protein origami as a new type of growth templates. The mesocrystals produced during the project will rapidly be exploited in advanced photonic devices in our group.

A multi-disciplinary (chemistry, biochemistry, microscopies) post-doctoral position for an experimental chemist is available in the Laboratoire Interdisciplinaire Carnot de Bourgogne (ICB, CNRS Univ. Bourgogne, Dijon, France) as part of a national collaborative research project gathering biochemists, physical chemists and cryo-electron-microscopists.
The initial 18-month contract may be extended depending on achievements.
The proposed work will be dedicated to the frontier field of anisotropic Au single crystal synthesis, surface chemistry, protein engineering applied to material science and advanced characterization using optical spectroscopy and transmission electron cryomicroscopy.
The research project will comprise three parts: (i) Development of new protocol for on-surface growth of ultrathin gold mesocrystals; (ii) surface functionalization with artificial proteins1 and spectroscopic investigations; (iii) structural characterization of protein origami designed to template the growth2 and assembly of optically active nanocrystals.3
Context:
Controlling the size, shape, interfaces and crystallinity of metallic nanostructures, in particular for plasmonic metals such as gold and silver, and mastering their coupling with other photo-active nanoparticles such as emitters, photocatalysts or photoactuators has expanded the scope of potential application fields of metal nanoparticles. Solution chemistry is now offering a variety of protocols to produce metal nanocrystals with well-defined shapes, size and surface chemistry. Yet two aspects remain challenging for their actual exploitation: (1) single crystallinity in anisotropic particles tends to be limited to a few micrometers and (2) the most effective chemical protocols rely on surface agents (surfactants, polymers) that irreversibly adhere to the metal surface and usually prevent further interfacial engineering.
