An Opto‐Actuated Hydrogel for Cell Mechanoactuation and Real‐Time Force Monitoring
Advanced Science, EarlyView.Researchers developed a mechanoactuated hydrogel interface where nanomachines exert forces on adhesion receptors and allow monitoring of traction force responses in real time. They demonstrate reversible talin recruitment, enhanced F‐actin polymerization, and a reduction in cell traction force when force is locally applied to focal adhesions of ...

Active Force Dynamics in Red Blood Cells Under Non‐Invasive Optical Tweezers
Advanced Science, EarlyView.A non‐invasive method combines low‐power optical tweezers with high‐speed microscopy to simultaneously monitor local membrane forces and displacements in single human red blood cells. This dual‐channel approach reveals a mechano‐dynamic signature that correlates the cell's metabolic state with its mechanical activity. This energetic framework serves as
