Each particle carries pH-responsive BODIPY dyes on its surface and a stable reference probe in the core, enabling ratiometric readouts. By decorating the membrane with Fcγ-binding ligands, we drive controlled uptake and capture the earliest steps of phagosome formation.

We introduce a modular biosensing strategy using targeted lipid microparticles to monitor phagosomal acidification in real time. These biomimetic particles are engineered to couple receptor-specific uptake with fluorescence-based pH reporting in macrophages.

We introduce a microfluidic device that can trap, analyze, and release individual microparticles on demand using membrane deformation driven by pneumatic pressure. The setup uses a deformable membrane suspended over an array of traps.

Our work on hydrodynamic instabilities in active jets is on the cover of PRL this week!
journals.aps.org/prl/abstract...
A dialogue between experiment and theory, where we use light to control active suspensions and show how they can be destabilized by their self-generated flows

A nice sky viewing night with family and kids, thanks to the Space Bus, in Corsica and under the full moon.

What if we could trap Lipid Droplets and control their dynamics in cells?
Our latest work does just that, using Engineered Condensates to manipulate LD behavior.
Exciting results by Chems Amari and the team!
Great collab with @abdourachidthiam.bsky.social
