DOI: 10.1002/1873-3468.12577
Abstract: The ciliated protozoan Vorticella convallaria is noted for its exceptionally fast adenosine triphosphate‐independent cellular contraction, but direct measurements of contractile force have proven difficult given the length scale, speed, and forces involved. We used high‐speed… read more here.
