Laser killing of cell nuclei has long been a powerful means of examining the roles of individual
cells in C. elegans. Advances in genetics, laser technology, and imaging have further …

We report a technique for quantitative three-dimensional (3D) mapping of refractive index in
live cells and tissues using a phase-shifting laser interferometric microscope with variable …

A single multimode fiber is considered an ideal optical element for endoscopic imaging due
to the possibility of direct image transmission via multiple spatial modes. However, the wave …

We report the experimental implementation of optical diffraction tomography for quantitative
3D mapping of refractive index in live biological cells. Using a heterodyne Mach-Zehnder …

We report that disordered media made of randomly distributed nanoparticles can be used to
overcome the diffraction limit of a conventional imaging system. By developing a method to …

We present an optogenetic illumination system capable of real-time light delivery with high
spatial resolution to specified targets in freely moving Caenorhabditis elegans. A tracking …

… enabled the targeted killing of specific cells in intact worms using a laser microbeam coupled
through a microscope; this approach has generated a great deal of our knowledge of C. …

One advantage of the nematode Caenorhabditis elegans as a model organism is its
suitability for in vivo optical microscopy. Imaging C. elegans often requires animals to be …

… Here we investigate this feat by studying the undulatory movements of C. elegans in
Newtonian … Our results suggest that C. elegans locomotory gait continuously adapts to external …

… In this study, we sought to identify the neural circuits that allow C. elegans to exhibit
different olfactory preferences depending on adult-stage experience. The nematode detects …
