Hydrodynamic and rheology of active polar filaments
Tanniemola B. Liverpool, M. Cristina Marchetti
The cytoskeleton provides eukaryotic cells with mechanical support and helps them perform their biological functions. It is a network of semiflexible polar protein filaments and ma…
Propulsion of a molecular machine by asymmetric distribution of reaction--products
Ramin Golestanian, Tanniemola B. Liverpool, Armand Ajdari
A simple model for the reaction-driven propulsion of a small device is proposed as a model for (part of) a molecular machine in aqueous media. Motion of the device is driven by an…
Designing phoretic micro- and nano-swimmers
R. Golestanian, T. B. Liverpool, A. Ajdari
Small objects can swim by generating around them fields or gradients which in turn induce fluid motion past their surface by phoretic surface effects. We quantify for arbitrary swi…
