A. Photonic crystals on chips to probe the viability of bacteria (work from a Pheliqs-LTM-LETI collaboration) B. Illustration of the principle of an electronic nose, from a SyMMES-Aryballe-LIPhy-IBS-LETI collaboration (J.Weerakkody, Graphical Abstract Labex Arcane Winner)

A. Passage of microswimmers through a constriction, new crowd model (LIPhy). B. Neural network on a network of microelectrodes (Institut Néel). C. Dynamics of bacterial DNA folding: Snapshot of a spatial conformation of a 60 kb molecule obtained by polymer physics simulation (TIMC-LIPhy).

A. Innovative radiotherapies allowing better targeting of irradiated structures: Microbeam radiotherapy by synchrotron radiation, boron neutron capture radiotherapy, vectorized internal radiotherapy, radiotherapy potentiated by nanoparticles. (STROBE). B. Microtissue composed of opto-genetically modified fibroblasts and surrounded by collagen (nucleus: blue, actin: green and collagen: magenta). Augmented blue light causes cells to contract; image analysis makes it possible to monitor deformation and mechanical stress. (LIPhy)

Some examples of bio-inspired materials. A: TiO2 microstructure film with anti-fouling properties, inspired by marine microflowers (LMGP); B: 3D mini-scaffold coated with biomimetic materials for cancer cell growth (BRM). C: Biodegradable needles containing arrays of flexible microelectrodes with nanostructured surfaces implanted in the brain of rats (Braintech).
