Mechanical forces are an integral part in biology, they regulate several cellular properties, such as morphology, proliferation, migration. These forces are also involved in receptor signaling and the differentiation of different cell types. Different proteins and biomolecules such as cadherin, integrin, notch proteins are essential elements of these processes. Measuring these intercellular forces are challenging considering the minimal intensity (piconewton-level) of these molecular forces. In our lab, we have developed a membrane DNA tension probe (MDTP) that uses a DNA hairpin module to sense tensile forces and has a lipid anchor to modify onto live-cell membranes. The programmability of DNA …
