a Temporal trace of forces and extensions during different force-jump events of a GQ-NS. A similar typical temporal trace of an anti-GQ-NS is presented in Supplementary Fig. 8. Two boxes marked as b and c in the traces represent recoiling and uncoiling events respectively. Magnified images for the b recoiling events of each nanosprings from 30 pN to 0.5 pN and c the uncoiling events from 0.5 to 1 pN. Spring constants for different nanosprings were calculated via Hooke’s Law (F/∆L) from d recoiling events and e uncoiling events. The errors refer to SD for n = 3 molecules.
