Modulating hydrodynamic flow by modifying the active patch of a colloid
Om Vandra, Suhal Siva Ratan T. N., Hemant Giri +4
We have developed a simulation model to study the hydrodynamic flow fields around Brownian colloidal particles with an active surface patch. Hydrodynamics is introduced by modeling…
Kinetics of segregation of topologically-modified ring polymers in cylindrical confinement
Harsh Doshi, Shreerang Pande, Sathish K. Sukumaran +1
In Escherichia coli (E. coli), entropic repulsion between the two daughter DNA ring polymers under cylindrical confinement is believed to be an important factor governing chromosom…
Entropic alignment of topologically modified ring polymers in cylindrical confinement
Sanjay Bhandarkar, Debarshi Mitra, Jürgen Horbach +1
Under high cylindrical confinement, segments of ring polymers can be localized along the long axis of the cylinder by introducing internal loops within the ring polymer. The emerge…
Entropic organization of topologically modified ring polymers in spherical confinement
Kingkini Roychoudhury, Shreerang Pande, Indrakanty S. Shashank +2
It has been shown that under high cylindrical confinement, two ring polymers with excluded volume interactions between monomers, segregate to two halves of the cylinder to maximize…
Topology mediated organization of E.coli chromosome in fast growth conditions
Shreerang Pande, Debarshi Mitra, Apratim Chatterji
Recent experiments have been able to visualise chromosome organization in fast-growing E.coli cells. However, the mechanism underlying the spatio-temporal organization remains poor…
