A microfluidic band-pass filter for flexible fiber separation

Sylvain Patinet — 2026-02-17T07:01:05Z

Flexible fibers are common in nature and technology, from biological filaments to nanomaterials and pollutants. However, sorting these deformable, anisotropic objects in flow remains difficult. We show that microfluidic devices with tilted pillar arrays-originally designed for spherical particles-can be adapted to separate fibers by length. Unexpectedly, these arrays act as band-pass filters, causing lateral migration only for fibers whose lengths match the interpillar spacing. This (…)

Lifetime and fluctuations of specific bonds between anisotropic colloids mediated through depletion interactions
To fabricate large-scale structures using colloidal particle self-assembly, one of the main challenges is to prevent kinetic trapping in metastable states. Therefore, interactions and colloids must be carefully chosen to ensure selectivity to guide the assembly, reversibility to enable large-scale reorganization and flexibility to finely tune colloid positioning. In pursuit of (…)

Science Festival at PMMH

Sylvain Patinet — 2025-09-18T16:38:12Z

The PMMH will be present at ESPCI (10 rue Vauquelin, 75005 Paris) on Saturday afternoon, October 4th, for open-access experimental demonstrations.
The laboratory will also welcome school groups on October 7th and 8th.
The laboratory tour will be divided into workshops providing a quick overview of the PMMH's research activities: wave propagation, kirigami, walking drops, tear propagation, soap bubbles, a mechanics workshop, dragonfly flight, superhydrophobic surfaces, and inflatable (…)
