To stick or not to stick:
a new understanding of condensates-membranes interactions

March 24, 2025

Sustainable & Bioinspired Materials

Challenge: It's not just whether a membrane is in a "solid" or "liquid" state that matters—how tightly its molecules are packed also influences how protein-rich droplets (condensates) stick to it
Finding: More tightly packed membranes push away condensates, while loosely packed ones attract them
Impact: Understanding these interactions is key to grasping essential cellular functions and disease progression

Revealing Bacteria’s True Colors:
Shimmering from Collective Patterns

July 12, 2024

Sustainable & Bioinspired Materials

Scientists can now predict structural colors in bacteria. By sequencing a wide range of bacterial DNA and developing an accurate predictive model, reseachers uncovered how bacteria organize themselves into specific patterns within colonies to interfere with light and create iridescence.Their findings hold great promise for sustainable, pigment-free color production.

From Nanotubes to Disks:
How Droplets Remodel Cell Membranes

June 21, 2024

Sustainable & Bioinspired Materials

Biomolecular condensates may play a crucial but overlooked role in remodeling membrane structures within cells. Rumiana Dimova and her team demonstrated that these droplets can shape parts of the endoplasmic reticulum into nanotubes and double-membrane discs without the need for specific curvature-molding proteins.

Sustainable & Bioinspired Materials

Imagine switching on a light and being able to understand and control the inner dynamics of a cell. This is what the Dimova group has achieved: by shining lights of different colors on replicates of cells, they altered the interactions between cellular elements. Controlling these complex interactions enables us to deliver specific drugs directly into the cells.

Little is known yet about the interaction between these biomolecular condensate droplets and the membrane-bound organelles. Researchers at the Max Planck Institute of Colloids and Interfaces in Potsdam developed synthetic membraneless organelles and visualized what happens when they meet a membrane.
