Great week at #ISMC2025 in Crete!
Sarika Chelur & Cristian Villalobos gave two great contributed talks, and our group leader, Laura, gave a #Keynote on our #JanusActiveVesicles
Huge thanks to the organizers & to everyone for inspiring discussions and fun moments!
#SoftBioColloids #SoftMatter
We are so proud of our @softbiocol.bsky.social group at #ISMC2025 🇬🇷!
Fantastic posters by Benjamín Oliva, José Fojo, Vivien Willems and Laura (PIs can also bring posters!)
🏆 Congrats to Vivien & Benjamín for winning #PosterPrizes! 🎉

Congratulations!!! 🥳
Not a promise, tho, a fact! :D
We are working on it!
Last weekend, we gathered to beat the heat with a lovely picnic, and to celebrate the recent tenure of our group leader @lauraal.bsky.social
Here’s to many more exciting years of science and friendship with you and those yet to join!
#softmatter @univbordeaux.bsky.social @crpp-bordeaux.bsky.social
Our group leader Laura's portrait is on the @cpjfrance.bsky.social website.
She holds a Chair Junior Maitre de Conference @univbordeaux.bsky.social @crpp-bordeaux.bsky.social

SoftBioColloids group portraits! 🗒️
We will be posting portraits of our group members, so you get to know a bit more about the people driving the science in the group.
We start with the portrait of Vivien Willems👇

📄 Run-and-tumble dynamics of active giant vesicles

Why it’s exciting:
- First time showing tunable run-and-tumble behavior in synthetic, soft lipid vesicles systems
- Reorientation is membrane-driven
- Behavior is encoded in lipid composition and electric field
During "tumbles", the membrane reconfigures, disrupting the Janus asymmetry.
The vesicle stops, loses directionality, then resumes motion in a new direction after phase structure recovers.
This is driven by field-induced membrane fluidity and tension.
These giant unilamellar vesicles (GUVs) have coexisting liquid-ordered and disordered lipid domains.
Under AC fields, asymmetric EHD flows along the membrane generate propulsion—as long as the Janus structure is intact.
Publication Alert!🎉
🚀🧪 New paper out! @softmatter.rsc.org @rsc.org
We show that Janus lipid vesicles can self-propel under AC electric fields, exhibiting run-and-tumble dynamics—just like bacteria, but driven by membrane-phase behavior.

The active softies of the group met some weeks ago to spend a nice evening together and enjoy some international delicacies!🧀🍷
What a blessing being surrounded by these amazing humans!

Frequency acts as a selector:
🔻Low freq → dipolar-driven networks
🔺High freq → standing rods, disconnection
Voltage tunes “stickiness.” Electric fields as on-demand glue.

🧲🧪 Field-tunable networks of colloidal rods!
AC fields induce reversible 2D percolated networks at area fractions below theoretical thresholds—dipolar attraction beats excluded volume. #SoftMatter #Colloids #SelfAssembly
