Paper: Active force maintains the stability of the contractile ring

Stanard Mebwe Pachong and Kristian Müller-Nedebock “Active force maintains the stability of a contractile ring” European Physical Journal E (2017) 40:91 DOI:10.1140/epje/i2017-11581-9 We discuss how motors in the contractile ring bring about its stability, separating the effects of the activity and the networking.

Winter School “The Biophysics of Cells and Macromolecules”, 4 July 2016

One of the traditional, one-day winter schools preceding the Annual Conference of the South African Institute of Physics this year will be on The Biophysics of Cells and Macromolecules. Please watch the conference web site for details that will be added there in the coming weeks. This year the conference is being held at the University of Cape Town.

Polymers and filaments in confined geometries

Imagine the filaments forming the cytoskeleton of a cell.  They are confined within the cell membrane.  Not only do these filaments influence how the cell might  behave mechanically, but how the filaments behave is coupled to the restricted space in which they grow, arrange or combine into networks.  Similarly one can think of polymers inside… Read More »

Paper: Molecular dynamics simulations of polymer systems under geometrical confinement

Arash Azari, Kristian K. Müller-Nedebock “Entropic competition in polymeric systems under geometrical confinement”, EPL 110 68004 doi:10.1209/0295-5075/110/68004 (alternatively, We present simulations of alternating copolymers of segments of different stiffness that are confined within regions.  Mixtures of different chains then have different arrangements depending on the size of the confining region. In another paper we shall be… Read More »
