Closed-loop control of active nematic flows
Katsu Nishiyama, John Berezney, Michael M. Norton +5
Living things enact control of non-equilibrium, dynamical structures through complex biochemical networks, accomplishing spatiotemporally-orchestrated physiological tasks such as c…
Active assembly and non-reciprocal dynamics of elastic membranes
John Berezney, Sattvic Ray, Itamar Kolvin +6
Equilibrium self-assembly and conventional materials processing techniques fall far short of mimicking dynamic self-actuating processes that are commonplace throughout biology. To…
Light-activated microtubule-based 2D active nematic
Zahra Zarei, John Berezney, Alexander Hensley +4
We characterize two-dimensional (2D) microtubule-based active nematics driven by light-responsive kinesin motor clusters. We assess two constructs of optogenetic kinesin: opto-K401…
Extensile to contractile transition in active microtubule-actin composites generates layered asters with programmable lifetimes
John Berezney, Bruce L. Goode, Seth Fraden +1
We study a reconstituted composite system consisting of an active microtubule network interdigitated with a passive network of entangled F-actin filaments. Increasing viscoelastici…
Shear-induced gelation of self-yielding active networks
David A. Gagnon, Claudia Dessi, John P. Berezney +4
Molecular-motor generated active stresses drive the cytoskeleton away from equilibrium, endowing it with tunable mechanical properties that are essential for diverse functions such…
Microtubule-based active fluids with improved lifetime, temporal stability and miscibility with passive soft materials
Pooja Chandrakar, John Berezney, Bezia Lemma +8
We have developed several distinct model systems of microtubule-based 3D active isotropic fluids and have compared their dynamical and structural properties. The non-equilibrium dy…
