Optical Antenna-based Fluorescence Correlation Spectroscopy to Probe the Nanoscale Dynamics of Biological Membranes
Pamina M. Winkler, Raju Regmi, Valentin Flauraud +4
The plasma membrane of living cells is compartmentalized at multiple spatial scales ranging from the nano- to the meso-scale. This non-random organization is crucial for a large nu…
Transient Nanoscopic Phase Separation in Biological Lipid Membranes Resolved by Planar Plasmonic Antennas
Pamina M. Winkler, Raju Regmi, Valentin Flauraud +4
Nanoscale membrane assemblies of sphingolipids, cholesterol, and certain proteins, also known as lipid rafts, play a crucial role in facilitating a broad range of important cell fu…
Planar Optical Nanoantennas Resolve Cholesterol-Dependent Nanoscale Heterogeneities in the Plasma Membrane of Living Cells
Raju Regmi, Pamina M. Winkler, Valentin Flauraud +6
Optical nanoantennas can efficiently confine light into nanoscopic hotspots, enabling single-molecule detection sensitivity at biological relevant conditions. This innovative appro…
Wavefront-sensing with a thin diffuser
Pascal Berto, Hervé Rigneault, Marc Guillon
We propose and implement a broadband, compact, and low-cost wavefront sensing scheme by simply placing a thin diffuser in the close vicinity of a camera. The local wavefront gradie…
Origin and suppression of parasitic signals in Kagomé lattice hollow core fibers used for SRS microscopy and endoscopy
Alberto Lombardini, Esben Ravn Andresen, Alexandre Kudlinski +2
Hollow core fibers are considered as promising candidates to deliver intense temporally overlapping picosecond pulses in applications such as stimulated Raman scattering (SRS) micr…
High-resolution multimodal flexible coherent Raman endoscope
Alberto Lombardini, Vasyl Mytskaniuk, Siddharth Sivankutty +8
Coherent Raman scattering microscopy is a fast, label-free and chemically specific imaging technique that has a high potential for future in-vivo optical histology. However, its im…
