Applications for Cell & Tissue Mechanobiology

optical tweezers application for cell mechanobiology: membrane tension and tether pulling
Tether Pulling

Study cell membrane mechanics in cells and explants performing tether pulling experiments. Use our customizable routines or create your own tether pulling routines.

optical tweezers application for cell mechanobiology: immune cell-cell interactions.
Immune Cells Interactions

Manipulate whole cells to engage cell-cell interactions and measure their binding forces while having absolute control on cells orientation and contact time. Use functionalized beads and/or substrates to measure in vitro receptor-ligand binding forces.

optical tweezers application for cell mechanobiology: micro-rheology
Active Micro-Rheology

Perform active & passive micro-rheology experiments in viscoelastic media like cell’s cytoplasm, hydrogels or biofilms.

optical tweezers application for cell mechanobiology: whole cell and nucleus shape deformation and stretching
Cell & Nucleus Deformation

Study cell membrane and cell nucleus mechanotransduction pathways by stretching the cell as a whole or manipulating the cell nucleus.

optical tweezers application for cell mechanobiology: membrane mechanoreceptors. Cell-ECM interactions
Cell-ECM Interactions

Study the dynamics and forces of transmembrane mechanoreceptors in cell-ECM interactions at the single-molecule level.

optical tweezers application for cell mechanobiology: motor proteins activity
In Vivo Motor Proteins Activity

​Study the activity and kinetics of motor proteins in vitro and in vivo. Measure stall forces of protein motors and observe tug-of-war and cooperating phenomena.
