We analyze this problem through scaling theory and simulations, and uncover a regime where filaments’ ends find each other through bending fluctuations without the need for the whole filament to diffuse. This results in a very substantial speedup of assembly in physiological regimes, and could help with understanding the dynamics of actin and intermediate filaments in biological processes such as wound healing and cell division."}],"date_updated":"2023-12-11T07:59:25Z","year":"2023","citation":{"ista":"Sorichetti V, Lenz M. 2023.

Here, we self-assemble polymer networks via simulations of a mixture of bivalent and tri- or tetravalent patchy particles, which result in an exponential strand length distribution analogous to that of experimental randomly cross-linked systems. After assembly, the network connectivity and topology are frozen and the resulting system is characterized. We find that the fractal structure of the network depends on the number density at which the assembly has been carried out, but that systems with the same mean valence and same assembly density have the same structural properties. Moreover, we compute the long-time limit of the mean-squared displacement, also known as the (squared) localization length, of the cross-links and of the middle monomers of the strands, showing that the dynamics of long strands is well described by the tube model. Finally, we find a relation connecting these two localization lengths at high density and connect the cross-link localization length to the shear modulus of the system.","lang":"eng"}],"day":"21","arxiv":1,"doi":"10.1063/5.0134271","external_id":{"pmid":["36813705"],"isi":["000936943800002"],"arxiv":["2211.04810"]},"isi":1,"year":"2023","citation":{"mla":"Sorichetti, Valerio, et al. “Structure and Elasticity of Model Disordered, Polydisperse, and Defect-Free Polymer Networks.” <i>Journal of Chemical Physics</i>, vol. 158, no. 7, 074905, American Institute of Physics, 2023, doi:<a href=\"https://doi.org/10.1063/5.0134271\">10.1063/5.0134271</a>.","short":"V.
