Automated high-content phenotyping from the first larval stage till the onset of adulthood of the nematode Caenorhabditis elegans

Martinus Adela Maria Gijs, Johan Auwerx, Matteo Cornaglia, Laurent Mouchiroud, Hüseyin Baris Atakan

The nematode Caenorhabditis elegans is increasingly used as a model for human biology. However, in vivo culturing platforms for C. elegans allowing high-content phenotyping during their life cycle in an automated fashion are lacking so far. Here, a multipl ...

Pedestal evolution physics in low triangularity JET tokamak discharges with ITER-like wall

The pressure gradient of the high confinement pedestal region at the edge of tokamak plasmas rapidly collapses during plasma eruptions called edge localised modes (ELMs), and then re-builds over a longer time scale before the next ELM. The physics that con ...

Analysis of ELM stability with extended MHD models in JET, JT-60U and future JT-60SA tokamak plasmas

The stability with respect to a peeling-ballooning mode (PBM) was investigated numerically with extended MHD simulation codes in JET, JT-60U and future JT-60SA plasmas. The MINERVA-DI code was used to analyze the linear stability, including the effects of ...

Interplay between the potential waveform and diffusion layer dynamics determines the time-response of voltammetric detection in microchannels

Martinus Adela Maria Gijs, Raphaël Etienne Jean Trouillon

The diffusion layer is a critical factor affecting the temporal response of electrochemical devices. In this article, we have investigated the effect of the relaxation of the diffusion layer during the potentiodynamic sensing of ferrocenemethanol (FcMeOH) ...

Delayed voltammetric with respect to amperometric electrochemical detection of concentration changes in microchannels

Martinus Adela Maria Gijs, Raphaël Etienne Jean Trouillon

The time response of an electrode incorporated into a fluidic channel to variations in analyte concentration of the outer-sphere redox probe ferrocenemethanol was investigated both for amperometry (AMP) and cyclic voltammetry (CV). The experimental data sh ...

Monolithic micro-direct methanol fuel cell in PDMS with microfluidic channel-integrated Nafion strip

Martinus Adela Maria Gijs, Meng Shen

We demonstrate a monolithic polymer electrolyte membrane fuel cell by integrating a narrow (200 mu m) Nafion strip in a molded polydimethylsiloxane (PDMS) structure. We propose two designs, based on two 200 mu m-wide and two 80 mu m-wide parallel microflui ...

Attomolar protein detection using a magnetic bead surface coverage assay

Martinus Adela Maria Gijs, Matteo Cornaglia, Hüseyin Cumhur Tekin

We demonstrate a microfluidic method for ultra-sensitive protein detection in serum. First, ‘large’ (2.8 μm) antibody-functionalized magnetic beads specifically capture antigen from a serum matrix under active microfluidic mixing. Subsequently, the large b ...

Studying the roundworm Caenorhabditis elegans using microfluidic chips

Martinus Adela Maria Gijs

C. elegans is an attractive model organism in biology, as it shows genetic similarity with humans, facilitates microscopic observation due to its transparency, and has a short life cycle. Moreover, many mutants expressing fluorescent proteins in particular ...
