A Retinal Matrix Stiffening Model Reveals FAK‐Dependent Mechanotransduction in Pericytes Underlies Vascular Destabilization

Advanced Materials, EarlyView.
In this study, we show that retinal matrix stiffness is increased in diabetic mice. Using engineered human vascular models with controlled matrix stiffness, we demonstrate that stiffening activates focal adhesion kinase (FAK) signaling in pericytes, suppresses Notch signaling, and disrupts vascular morphology.

Life‐Like Ferrous Oxide Microspheres from Kombucha

Advanced Materials Interfaces, EarlyView.
Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

Interface Dynamics in Biomolecular Condensates by High‐Speed AFM

Advanced Materials Interfaces, EarlyView.
High‐speed atomic force microscopy provides nanoscale structural dynamics at the liquid interface of biomolecular condensates, key elements in several cellular pathways. By addressing the challenges of low surface tension and condensate‐induced instabilities, we achieve nanometer spatial and sub‐second temporal resolution, revealing structural ...

Using molecular dynamics simulation to examine the evolution of blood barrier structure in the presence of different electric fields

International Journal of Thermofluids
Membrane disruption refers to increasing cell membrane permeability. This state may be transient, allowing the cell to regain its function, or it can be lasting, resulting in the cell's demise.
