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! 🎉

🎨🔬 In our lab, science meets art! From vibrant colors to stunning shapes, our experiments are as beautiful as they are fascinating. Because science is art!

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!

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👇

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

Excited to share the new preprint on reconfigurable colloidal molecules, led by S. Ketzetzi, in collab. with H. Löwen and L. Isa. Congrats to Vivien (first article from her Master’s) & @lauraal.bsky.social for their contribution, and to all for the great work!

We are thrilled to be part of the #SigSynCell European DN

We will focus on the fabrication and manipulation of giant lipid vesicles with diverse architectures for motility, reconfiguration and signalling.
