Research Fields

Self-assembly of polymer materials or micro-nano-particles

S.Gree, L.Josien, V.Luchnikov, J.-P. Malval, K.Mougin

Self-assembly and controlled deformation of polymer thin films are used to prepare surfaces with chemical contrast or curvature at the micro and nanometric scales. Patterned surfaces allow the controlled deposition of metal nanoparticles for applications in sensors. Curved polymer thin films can form microtubes with practical applications for drug delivery.

Liquid-solid interfaces on complex surfaces, wetting, dewetting

M.Nardin, L.Vonna

Interparticle interactions between micro- and nano-objects are characterized to investigate the cohesion of particles-based materials. Liquid-solid interfaces at the microscale are also considered to study wetting and dewetting on micro-nano-patterned surfaces.

Photopolymers and functional materials for photostructuration

D.Berling, J.-P.Malval, O.Soppera, A.Sprangenberg

Original functional materials compatible with photopatterning are developed to obtain multifunctional micro-nano-structures. Among others, photo-materials, molecularly imprinted polymers (MIP), hybrid materials with electrical or magnetic properties, sol-gel materials for optical or photonic application were prepared and patterned with our different photoinduced micro-nano-patterning setups.

Unconventional photostructuration processes

J.-P. Malval, B.Leuschel, O. Soppera, A. Spangenberg

New original strategies for light-induced micro- and nano-fabrication have been developed. Some recent examples include laser direct-writing, 3D printing, 2-photon stereolithography, interferometry lithography, optical near-field lithography, self-guiding lithography… Photoresists compatible with these fabrication processes can cover a wide range of wavelengths from Deep-UV to Near-Infrared.
