Mechanoactive Biomaterials for Cell–Matrix Mechanotransduction
Advanced Materials, EarlyView.The graphical abstract shows how individual triggers (force, light, or temperature) and combined optothermal or receptor‐targeted actuation induce material responses at the tissue, cellular, and receptor scales. Their spatial (global or focused) and temporal (continuous or cyclic) modulation determines the resulting mechanical output.
