About

Violaine Chapuis is a pioneering researcher in microfluidics and lab-on-a-chip technologies, with a focus on precision cell manipulation and single-cell analysis. Her most cited work, "Electrical Detection and Ejection of Beads in a One-Cell-Per-Drop Microdispenser" (2007, 12 citations), introduces a groundbreaking microfluidic device capable of detecting individual cells within a channel and ejecting them into nanoliter-sized droplets. This innovation enables the precise dispensing of a controlled number of cells onto a target spot, a critical advancement for cell-based assays, drug screening, and personalized medicine. Chapuis’s contributions lie at the intersection of electrical sensing and microfluidic actuation, offering a non-invasive, high-throughput method for single-cell isolation. Her work has laid the foundation for scalable platforms in cellular biology, reducing sample waste and improving assay accuracy. Though her citation count reflects a niche but impactful focus, her research has influenced the development of droplet-based microdispensers used in diagnostics and biotechnology. Chapuis’s achievements highlight her role in advancing microfluidic tools that bridge engineering and biology, making her a notable figure in the field of micro total analysis systems.
