A mechanical model of bacteriophage DNA ejection
Rahul Arun, Sandip Ghosal
Single molecule experiments on bacteriophages show an exponential scaling for the dependence of mobility on the length of DNA within the capsid. It has been suggested that this cou…
Studying DNA translocation in nanocapillaries using single molecule fluorescence
Vivek V. Thacker, Sandip Ghosal, Silvia Hernández-Ainsa +2
We demonstrate simultaneous measurements of DNA translocation into glass nanopores using ionic current detection and fluorescent imaging. We verify the correspondence between the p…
Capstan friction model for DNA ejection from bacteriophages
Sandip Ghosal
Bacteriophages infect cells by attaching to the outer membrane and injecting their DNA into the cell.The phage DNA is then transcribed by the cell's transcription machinery.A numbe…
Ion transport through a graphene nanopore
Guohui Hu, Mao Mao, Sandip Ghosal
Molecular dynamics simulation is utilized to investigate the ionic transport of NaCl in solution through a graphene nanopore under an applied electric field. Results show the forma…
Electrokinetic-flow-induced viscous drag on a tethered DNA inside a nanopore
Sandip Ghosal
Recent work has shown that the resistive force arising from viscous effects within the pore region could explain [Ghosal, S. Phys. Rev. E. vol. 71, 051904 (2006) and Phys. Rev. Let…
Electromigration dispersion in Capillary Electrophoresis
Zhen Chen, Sandip Ghosal
In a previous paper (S. Ghosal and Z. Chen Bull. Math. Biol. 2010, vol. 72, pg. 2047) it was shown that the evolution of the solute concentration in capillary electrophoresis is de…
