An electro-osmotic instability in biological cells

The development of ionic currents during the growth of biological cells contributes to the generation of spatial order. A new instability is proposed to describe such phenomenon. The mechanism triggering the instability is based on electro-osmosis flow which generates aggregation of channels or pump...

Description
Summary:The development of ionic currents during the growth of biological cells contributes to the generation of spatial order. A new instability is proposed to describe such phenomenon. The mechanism triggering the instability is based on electro-osmosis flow which generates aggregation of channels or pumps. The onset of unstable modes and the dispersion relation are determined and a comparison with a biological cell is provided.
