Probing single-molecule dynamics in self-assembling viral nucleocapsids

All viruses on Earth rely on host cell machinery for replication, a process that involves a complex self-assembly mechanism. Our aim here is to scrutinize in real time the growth of icosahedral viral nucleocapsids with single-molecule precision…

Exploring non-Euclidean photonics: Pseudosphere microlaser

Classical and wave properties of microlasers with the shape of a truncated pseudosphere are investigated through experiments and numerical simulations. These pseudosphere microlasers are surface-like organic microlasers with constant negative…

Spectro-FLIM for heritage: scanning and analysis of the time resolved luminescence spectra of a fossil shrimp

Nous décrivons l'utilisation d'un dispositif d'imagerie par comptage de photons uniques pour scanner la surface d'un spécimen fossile plat. Nous avons étudié une crevette du Trias précoce identifiée comme Anisaeger longirostrus, du biote de Paris …

Carbon Dot Synthesis in CYTOP Optical Fiber Using IR Femtosecond Laser Direct Writing and Its Luminescence Properties

Luminescent carbon dots (CDs) were locally synthesized in the core of CYTOP fibers using IR femtosecond laser direct writing (FLDW), a one-step simple method serving as a post-treatment of the pristine fiber. This approach enables the creation of…

3D real-time single particle tracking using two-photon fluorescence from bright dye-based organic nanoparticles

This paper addresses the use of ultrabright dye-based fluorescent organic nanoparticles in a 3D single-particle tracking two-photon microscopy setup. The nanoparticles consist of an assembly of quadrupolar dyes, presenting a large two-photon…

Optical properties of fs laser-created sphere inside CYTOP fiber by Mueller polarimetry

Optical elements embedded in an optical fiber can be used to shape and modulate the light transmitted within. We consistently observe, via Mueller polarimetry, that the optical properties of a femtosecond (fs) laser-created spherical cavity within a…

Direct fabrication of rough gold nanoholes and investigation of their second-harmonic generation

Abstract In this study, we introduce a simple and cost-effective technique called one-photon absorption-based direct laser writing (OPA-based DLW) to directly fabricate noncentrosymmetric gold nanoholes (Au NHs). This technique relies on the…
