Frontiers in fluorescence microscopy
How we see organisms and cells depends on the tools at our disposal. For over 150 years, biologists were forced to rely on fixed, dehydrated and stained specimens in order to guess how the living cells could function. It all changed abruptly during the last two decades when the rapid development of novel imaging techniques revolutionized the way ...

Tip-Enhanced Fluorescence Microscopy at 10 Nanometer Resolution [PDF]
We demonstrate unambiguously that the field enhancement near the apex of a laser-illuminated silicon tip decays according to a power law that is moderated by a single parameter characterizing the tip sharpness.

Wide field fluorescence epi-microscopy behind a scattering medium enabled by speckle correlations [PDF]
Fluorescence microscopy is widely used in biological imaging, however scattering from tissues strongly limits its applicability to a shallow depth. In this work we adapt a methodology inspired from stellar speckle interferometry, and exploit the optical memory effect to enable fluorescence microscopy through a turbid layer.

Instant three-color multiplane fluorescence microscopy
One of the most widely used microscopy techniques in biology and medicine is fluorescence microscopy, offering high specificity in labeling as well as maximal sensitivity. For live-cell imaging, the ideal fluorescence microscope should offer high spatial

Light Sheet Fluorescence Microscopy Illuminating Soft Matter
Volumetric microscopic imaging data acquired at high speeds is often needed in studies of soft matter. Several microscopy techniques exist for this purpose, but a relative newcomer is light sheet fluorescence microscopy (LSFM). This microscopy method has

Bridging fluorescence microscopy and electron microscopy [PDF]
Development of new fluorescent probes and fluorescence microscopes has led to new ways to study cell biology. With the emergence of specialized microscopy units at most universities and research centers, the use of these techniques is well within reach for a broad research community.

Compressed sensing in fluorescence microscopy
Compressed sensing (CS) is a signal processing approach that solves ill-posed inverse problems, from under-sampled data with respect to the Nyquist criterium. CS exploits sparsity constraints based on the knowledge of prior information, relative to the structure of the object in the spatial or other domains.

Elastohydrodynamic study of actin filaments using fluorescence microscopy [PDF]
We probed the bending of actin subject to external forcing and viscous drag. Single actin filaments were moved perpendicular to their long axis in an oscillatory way by means of an optically tweezed latex bead attached to one end of the filaments. Shapes

Fourier imaging study of efficient near-field optical coupling in solid immersion fluorescence microscopy [PDF]
We measured images and Fourier images of fluorescence for 0.11- and 0.22-$\mu$m-diameter dye-doped polystyrene micro-sphere beads on a solid immersion lens, and experimentally verified strongly-angle-dependent fluorescence intensities due to efficient near-field optical coupling in solid immersion fluorescence microscopy. The results are interpreted in
