Imagerie dans le brouillard à longue distance

D’une rencontre en 1999 naît une aventure scientifique entre le Raman Research Institute de Bangalore (Inde) et deux laboratoires français autour de l’imagerie en milieux diffusants à longue distance pour l’imagerie en conditions de visibilité…

Möbius strip microlasers

Direct laser writing [1] enables the fabrication of almost arbitrary three-dimensional (3d) microstructures with feature sizes of less than 1 µ m and allows to create 3d organic microlasers such as pyramids with high quality and low surface…

Harnessing subcellular-resolved organ distribution of cationic copolymer-functionalized fluorescent nanodiamonds for optimal delivery of therapeutic siRNA to a xenografted tumor in mice

Diamond nanoparticles (nanodiamonds) can transport active drugs in cultured cells as well as in vivo. However, in the latter case, methods allowing to determine their bioavailability accurately are still lacking. Nanodiamond can be made fluorescent…

A versatile microfluidic tool for the 3D culture of HepaRG cells seeded at various stages of differentiation

Abstract The development of livers-on-a-chip aims to provide pharmaceutical companies with reliable systems to perform drug screening and toxicological studies. To that end, microfluidic systems are engineered to mimic the functions and architecture…

Möbius Strip Microlasers: A Testbed for Non-Euclidean Photonics

We report on experiments with Möbius strip microlasers, which were fabricated with high optical quality by direct laser writing. A Möbius strip, i.e., a band with a half twist, exhibits the fascinating property that it has a single nonorientable…

Solution-processed graphene–nanographene van der Waals heterostructures for photodetectors with efficient and ultralong charge separation

Sensitization of graphene with inorganic semiconducting nanostructures has been demonstrated as a powerful strategy to boost its optoelectronic performance. However, the limited tunability of optical properties and toxicity of metal cations in the…
