Probe can measure both cell stiffness and traction, researchers report

January 27, 2023

Scientists have developed a tiny mechanical probe that can measure the inherent stiffness of cells and tissues as well as the internal forces the cells generate and exert on one another. Their new “magnetic microrobot” is the first such probe to be able to quantify both properties, the researchers report, and will aid in understanding cellular processes associated with development and disease.

They detail their findings in the journal Science Robotics.

Fast-acting, color-changing molecular probe senses when material about to fail

March 25, 2021

Materials that contain special polymer molecules may someday be able to warn us when they are about to fail, researchers said. Engineers at the University of Illinois Urbana-Champaign have improved their previously developed force-sensitive molecules, called mechanophores, to produce reversible, rapid and vibrant color change when a force is applied.
