Here we propose a novel approach to probe individual peripheral stress fibers in living cells through a microsurgically generated opening in the cytoplasm. By applying large deformations with a soft cantilever we were able to fully characterize the mechanical response of the fibers and evaluate their tension, extensibility, elastic and viscous properties.Microsurgery-aided in-situ force probing reveals extensibility and viscoelastic properties of individual stress fiberstext::journal::journal article::research article
