Active Particles Imprint Persistent Percolating Networks in Polymer Condensates
Ligesh Theeyancheri, Jennifer L. Ross, J. M. Schwarz
Fluid condensates readily exchange components and reorganize, and in doing so typically erase structural history. Using simulations of sticker-spacer polymers in an active particle…
Cell strain-stiffening drives cell breakout from embedded spheroids
Shabeeb Ameen, Kyungeun Kim, Ligesh Theeyancheri +5
Understanding how cells escape from embedded spheroids requires a mechanical framework linking stress generation within cells, across cells, and between cells and the surrounding e…
Enzyme Active Bath Affects Protein Condensation
Kevin Ching, Anthony Estrada, Nicholas M Rubayiza +3
We investigate how an active bath of enzymes influences the liquid-liquid phase separation (LLPS) of a non-interacting condensing protein. The enzyme we choose to use as the active…
Differential Crosslinking and Contractile Motors Drive Nuclear Chromatin Compaction
Ligesh Theeyancheri, Edward J. Banigan, J. M. Schwarz
During interphase, a typical cell nucleus features spatial compartmentalization of transcriptionally active euchromatin and repressed heterochromatin domains. In conventional nucle…
Dynamic Clustering of Active Rings
Ligesh Theeyancheri, Subhasish Chaki, Tapomoy Bhattacharjee +1
A collection of rings made of active Brownian particles (ABPs) for different packing fractions and activities is investigated using computer simulations. We show that active rings…
Active Dynamics of Linear Chains and Rings in Porous Media
Ligesh Theeyancheri, Subhasish Chaki, Tapomoy Bhattacharjee +1
To understand the dynamical and conformational properties of deformable active agents in porous media, we computationally investigate the dynamics of linear chains and rings made o…
A Polymer Chain with Dipolar Active Forces in Connection to Spatial Organization of Chromatin
Subhasish Chaki, Ligesh Theeyancheri, Rajarshi Chakrabarti
A living cell is an active environment where the organization and dynamics of chromatin are affected by different forms of activity. Optical experiments report that loci show subdi…
Transport of a self-propelled tracer through a hairy cylindrical channel: interplay of stickiness and activity
Rajiblochan Sahoo, Ligesh Theeyancheri, Rajarshi Chakrabarti
Active transport of biomolecules assisted by motor proteins is imperative for the proper functioning of cellular activities. Inspired by the diffusion of active agents in crowded c…
Chemically symmetric and asymmetric self-driven rigid dumbbells in 2D polymer gel
Praveen Kumar, Ligesh Theeyancheri, Rajarshi Chakrabarti
We employ computer simulations to unveil the translational and rotational dynamics of the self-driven chemically symmetric and asymmetric rigid dumbbells in two-dimensional polymer…
Migration of Active Rings in Porous Media
Ligesh Theeyancheri, Subhasish Chaki, Tapomoy Bhattacharjee +1
Inspired by how the shape deformations in active organisms help them to migrate through disordered porous environments, we simulate active ring polymers in two-dimensional random p…
Translational and rotational dynamics of a self-propelled Janus probe in crowded environments
Ligesh Theeyancheri, Subhasish Chaki, Nairhita Samanta +3
We computationally investigate the dynamics of a self-propelled Janus probe in crowded environments. The crowding is caused by the presence of viscoelastic polymers or non-viscoela…
Choline chloride as a nano-crowder protects HP-36 from urea-induced denaturation: Insights from Solvent Dynamics and Protein-Solvent interaction
Atanu Maity, Soham Sarkar, Ligesh Theeyancheri +1
Urea at sufficiently high concentration unfolds the secondary structure of proteins leading to denaturation. In contrast, Choline Chloride (ChCl) and urea, in 1:2 molar ratio form…
Transport of probe particles in polymer network: effects of probe size, network rigidity and probe-polymer interaction
Praveen Kumar, Ligesh Theeyancheri, Subhasish Chaki +1
Fundamental understanding of the effect of microscopic parameters on the dynamics of probe particles in different complex environments has wide implications. Examples include diffu…
