Sub-millisecond electric field sensing with an individual rare-earth doped ferroelectric nanocrystal
Autor: Muraleedharan, Athulya, Zou, Jingye, Vallet, Maxime, Zaki, Abdelali, Bogicevic, Christine, Paillard, Charles, Perronet, Karen, Treussart, François
Understanding the dynamics of electrical signals within neuronal assemblies is crucial to unraveling complex brain function. Despite recent advances in employing optically active nanostructures in transmembrane potential sensing, there remains room f

Ferroelectric texture of individual barium titanate nanocrystals
Autor: Muraleedharan, Athulya, Co, Kevin, Vallet, Maxime, Zaki, Abdelali, Karolak, Fabienne, Bogicevic, Christine, Perronet, Karen, Dkhil, Brahim, Paillard, Charles, Fiorini-Debuisschert, Céline, Treussart, François
Publikováno v: ACS Nano, 2024
Ferroelectric materials display exotic polarization textures at the nanoscale that could be used to improve the energetic efficiency of electronic components. The vast majority of studies were conducted in two dimensions on thin films, that can be fu

Two-photon real-time device for single-particle holographic tracking (red shot)
Autor: Semmer, Florian, Emperauger, Marie-Charlotte, Lopez, Colin, Bogicevic, Christine, Treussart, François, Perronet, Karen, Marquier, François
Three-dimension real-time tracking of single emitters is an emerging tool for assessment of biological behavior as intraneuronal transport, for which spatiotemporal resolution is crucial to understand the microscopic interactions between molecular mo

Statistical Tests for Force Inference in Heterogeneous Environments
Autor: Serov, Alexander S., Laurent, François, Floderer, Charlotte, Perronet, Karen, Favard, Cyril, Muriaux, Delphine, Vestergaard, Christian L., Masson, Jean-Baptiste
We devise a method to detect and estimate forces in a heterogeneous environment based on experimentally recorded stochastic trajectories. In particular, we focus on systems modeled by the heterogeneous overdamped Langevin equation. Here, the observed

Accurate calibration of optical tweezers close to a glass surface using interference rings in backscattered light
Autor: Gillant Flavie, Moreau Julien, Richly Maximilian U., Alexandrou Antigoni, Perronet Karen, Westbrook Nathalie
Publikováno v: Journal of the European Optical Society-Rapid Publications, Vol 19, Iss 1, p 28 (2023)
Mechanical forces play an important role in the behaviour of cells, from differentiation to migration and the development of diseases. Optical tweezers provide a quantitative tool to study these forces and must be combined with other tools, such as p
