Force generation by a propagating wave of supramolecular nanofibers

R. Kubota, M. Makuta, et al.

Exciting research by Ryou Kubota and colleagues unveils the mechanics of force generation through a traveling wave of supramolecular nanofibers. Explore how innovative stimuli control the creation and breakdown of these nanofibers, leading to measurable forces that can even propel nanobeads!

Abstract
This paper describes force generation by a propagating wave of supramolecular nanofibers. A reaction network was designed to control the formation and degradation of nanofibers using two orthogonal stimuli. Real-time fluorescent imaging visualized the propagating wave. Numerical simulation showed that the concentration gradient of the degradation stimulus and the lower diffusion coefficient of the nanofiber were crucial for wave emergence. The generated force (0.005 pN) moved nanobeads.
