A model to describe the cavitation‐induced breakage of nanofilaments during their sonication in solution is proposed. The model predicts a limiting length below which scission no longer occurs, and accurately describes experimental results for materials ranging from carbon nanotubes to protein fibrils. Sonication‐induced breakage can now be used as a probe for the strength of nanostructures.
