A first step towards truly quantitative TIRF microsopy
Total internal reflection and other near-field optical techniques excel in selectively imaging dynamic processes at or near the basal plasma membrane, e.g., single-receptor or single-vesicle dynamics. However, it has been difficult to quantify TIRF int ...
Characterizing nanometric axial distance with far-field light
A group of researchers around Adi Salomon (BINA Nanocenter, Ramat-Gan, Israel) and Martin Oheim (SPPIN) have developed a simple nanometric calibration tool for axial super-resolution imaging. In a pre-print available on biorXiv, they describe a simpl ...
Our first work on the enteric nervous system, the “brain in the gut” is out!

Understanding the effect of scattered evanescent light
Evanescent-wave scattering is a topic in classical electrodynamics and in the study of colloidal particles near a boundary. However, how such near-surface scattering at sub-cellular refractive-index heterogeneities degrades the excitation confinement ...
A nutrient sensor in the cell’s stomach | INSB (cnrs.fr)
© Solène Lebrun & Bruno Gasnier To stay in good health, cells that no longer divide such as neurons renew their components by degrading them and recycling their building blocks in acidic compartments called lysosomes. These “micro-stomachs” ...
Complex scattered light-field measurement with a simple wavefront-sensor
Wavefront sensors are simple and robust phase sensors at the basis of adaptive optics in astronomy and bio-imaging. Adaptive optics has been introduced in bio-imaging to compensate smooth aberrations mostly arising from the refractive index mismatch a ...
A simple, inexpensive and multi-scale 3-D fluorescent test sample for optical sectioning microscopies
Pyranine-labeled tissue paper, imaged upon 405-nm epifluorescence excitation through a 455LP LP dichroic and 465LP emission filter. Objective ×20/NA0.25. Overlaid are the normalised absorbance (dashed) and emission spectra (through line), respectively. I ...
Heating, not highly non-linear photo damage is limiting for 920-nm 2-imaging
Unraveling how neural networks process and represent sensory information and how these cellular signals instruct behavioral output is a main goal in neuroscience. Two-photon activation of optogenetic actuators and calcium (Ca 2+) imaging with gen ...
Spectral correlations in forward scattering media
Artist illustration of chromatic speckle expansion after a scattering sample. (© Clément Molinier) Imaging deep in scattering tissues has been typically achieved by exciting non-linear optical processes thanks to broadband ultrashort laser pulses. Scatte ...
Evanescence in emission: seeing fluorescence from supercritical angles
Read it here : Supercritical angle microscopy and spectroscopy Authors: Martin Oheim, Adi Salomon, Maia Brunstein Abstract: Fluorescence detection, either involving propagating or near-field emission, is widely being used in spectroscopy, sensing and micro ...
