Arrays of plasmonic nanocavities with very low volumes, down to λ(3)/1000, have been fabricated by soft UV nanoimprint lithography. Nearly perfect omnidirectional absorption (3-70°) is demonstrated for the fundamental mode of the cavity (λ ≃ 1.15 μm). The second-order mode exhibits a sharper resonance with strong angular dependence and total optical(More)
Mobile microrobots have a promising future in various applications. These include targeted drug delivery, local measurement, biopsy or microassembly. Studying mobile microrobots inside microfluidics is an essential step towards such applications. But in this environment that was not designed for the robot, integration process and propulsion robustness still(More)
Magnetically actuated helical nanoswimmers have various potential applications from in-vitro microfluidics to invivo less invasive surgery. However these applications provide more challenging environments for the helical nanoswimmers by often limiting their mobility robustness from their limited motion dexterity. That is why we propose in this paper a(More)
We study the edge diffraction enhanced printability in x-ray nanolithography under both proximity and soft-contact printing conditions. Theoretical modeling shows that the gap dependence of the edge diffraction is closely related to that of the minimum linewidth described by the common Fresnel formula and that the edge diffraction can significantly enhance(More)
Structured luminescent thin films are investigated in the context of improved light extraction of phosphors for solid-state-lighting applications. Thin films composed of a sol-gel titania matrix doped with europium chelates are studied as a model system. These films, patterned with a square photonic lattice by soft nanoimprint lithography, are characterized(More)
Recent advances in large area graphene growth have led to tremendous applications in a variety of areas. The graphene nanomesh with its tunable band-gap is of great interest for both fundamental research, to explore the effect of edges on both the 2D electrical conduction and its electrochemical behavior, and applications such as nanoelectronic devices or(More)
In-vivo and in-vitro micro-interventions by mobile robotic agents require their precise control. Numerous types of microrobotic swimmers have been developed, assuming different peculiar applications, but often suffering from a lack of mobility and robustness, due to their unique propulsion mode. Hence we present in this paper the multi-flagella helical(More)
Microswimmers integrated into microfluidic devices that are capable of self-illumination through fluorescence could revolutionize many aspects of technology, especially for biological applications. Few illumination and propulsion techniques of helical microswimmers inside microfluidic channels have been demonstrated. This paper presents the fabrication,(More)
Magnetically actuated micro/nano robots are promising to various biological and medical applications in wet environments. In order to improve robots control, robustness and efficiency, real time 3D topographical surface analysis are essential especially for their navigation under such wet and confined environments. In this paper we propose a swimmer from(More)
Helical microstructures present large force and deformation range that give them good potential to become mechanical force sensors at the microscale. Various materials and processes have been proposed but their real life applications especially in wet/air environments are still very few mainly due to their mechanical robustness and non-linearity. Polymer(More)
