Mechanical forces are integral to many biological processes; however, current techniques cannot map the magnitude and direction of piconewton molecular forces. Here, we describe molecular force microscopy, leveraging molecular tension probes and fluorescence polarization microscopy to measure the magnitude and 3D orientation of cellular forces. We mapped the orientation of integrin-based traction forces in mouse fibroblasts and human platelets, revealing alignment between the organization of force-bearing structures and their force vectors. Molecular force microscopy employs a combination of fluorescence polarization microscopy and molecular tension sensors to determine the orientation of cellular forces. The technology is demonstrated for integrin-mediated forces in platelets and fibroblasts.
