Microfluidic culture platforms for C. elegans bacterial interaction and digestion studies at single-organism resolution

Increasing interest in understanding fundamental biological processes, among which aging and nutrition, has led to the study of simple and powerful model organisms, as the round-worm Caenorhabditis elegans (C. elegans). The nematode, selected by Sydney Bre ...

An In Vivo Microfluidic Study of Bacterial Load Dynamics and Absorption in the C. elegans Intestine

Martinus Gijs, Thomas Lehnert, Vittorio Viri, Maël Arveiler

Caenorhabditiselegans (C. elegans) has gained importance as a model for studying host-microbiota interactions and bacterial infections related to human pathogens. Assessing the fate of ingested bacteria in the worm's intestine is therefore of great interes ...

Integration of polymeric membrane/dielectric sphere assemblies in microfluidic chips for enhanced-contrast imaging with low-magnification systems

Martinus Gijs, Daniel Migliozzi, Vittorio Viri

Current microscopy systems for the imaging of microorganisms are expensive because of their optimized design toward resolution maximization and aberration correction. In situations where such an optimization is not needed, for instance to merely detect the ...

Anin vivomicrofluidic study of bacterial transit inC. elegansnematodes

Martinus Gijs, Thomas Lehnert, Matteo Cornaglia, Hüseyin Baris Atakan, Vittorio Viri

Caenorhabditis elegans(C. elegans) constitutes an important model organism for use in nutrition and aging studies. We report a novel method for studying the dynamics ofEscherichia coli(E. coli) bacterial transit through the worms' intestine. A microfluidic ...
