Harnessing the power of chemically active sheets in solution

RK Manna, A Laskar, OE Shklyaev… - Nature Reviews …, 2022 - nature.com
In living organisms, diffusing chemicals react with soft tissue to actuate a range of
mechanical actions, such as periodic pulsations or net motion. Inspired by this biological …

Spontaneous oscillations of elastic filaments induced by molecular motors

G De Canio, E Lauga… - Journal of The Royal …, 2017 - royalsocietypublishing.org
It is known from the wave-like motion of microtubules in motility assays that the piconewton
forces that motors produce can be sufficient to bend the filaments. In cellular phenomena …

Structure and dynamics of a self-propelled semiflexible filament

SK Anand, SP Singh - Physical Review E, 2018 - APS
We investigate structural and dynamical properties of a self-propelled filament using coarse-
grained Brownian dynamics simulations. A self-propulsion force is applied along the bond …

Collapse dynamics of chemically active flexible polymer

N Jain, S Thakur - Macromolecules, 2022 - ACS Publications
We investigate the structural and dynamical properties of a chemically active flexible
polymer chain immersed in a solvent bath by using hybrid molecular dynamics (MD) and …

Conformation and dynamics of a self-avoiding active flexible polymer

SK Anand, SP Singh - Physical Review E, 2020 - APS
We investigate conformations and dynamics of a polymer considering its monomers to be
active Brownian particles. This active polymer shows very intriguing physical behavior which …

Synchronized oscillations, traveling waves, and jammed clusters induced by steric interactions in active filament arrays

R Chelakkot, MF Hagan, A Gopinath - Soft matter, 2021 - pubs.rsc.org
Autonomous active, elastic filaments that interact with each other to achieve cooperation and
synchrony underlie many critical functions in biology. The mechanisms underlying this …

Buckling instabilities and spatio-temporal dynamics of active elastic filaments

Y Fily, P Subramanian… - Journal of the …, 2020 - royalsocietypublishing.org
Biological filaments driven by molecular motors tend to experience tangential propulsive
forces also known as active follower forces. When such a filament encounters an obstacle, it …

Linking catalyst-coated isotropic colloids into “active” flexible chains enhances their diffusivity

B Biswas, RK Manna, A Laskar, PBS Kumar… - ACS …, 2017 - ACS Publications
Active colloids are not constrained by equilibrium: ballistic propulsion, superdiffusive
behavior, or enhanced diffusivities have been reported for active Janus particles. At high …

Twist and turn: elastohydrodynamics of microscale active fibres

M Lisicki - The European Physical Journal Special Topics, 2024 - Springer
Cellular locomotion often involves the motion of thin, elastic filaments, such as cilia and
flagella, in viscous environments. The manuscript serves as a general introduction to the …

Emergent programmable behavior and chaos in dynamically driven active filaments
