Effects of Molecular Crowding on stretching of polymers in poor solvent
Amit Raj Singh, Debaprasad Giri, Sanjay Kumar
We consider a linear polymer chain in a disordered environment modeled by percolation clusters on a square lattice. The disordered environment is meant to roughly represent molecul…
Role of pulling direction in understanding the energy landscape of proteins
R. Rajesh, D. Giri, I. Jensen +1
Single molecule force spectroscopy provide details of the underlying energy surfaces of proteins which are essential to the understanding of their unfolding process. Recently, it h…
Does changing the pulling direction give better insight into biomolecules?
Sanjay Kumar, Debaprasad Giri
Single molecule manipulation techniques reveal that the mechanical resistance of a protein depends on the direction of the applied force. Using a lattice model of polymers, we show…
Statistical mechanics of coil-hairpin transition in a single stranded DNA oligomer
Sanjay Kumar, Debaprasad Giri, Yashwant Singh
A model of self-avoiding walk with suitable constraints on self-attraction is developed to describe the conformational behavior of a short RNA or a single stranded DNA molecule tha…
Force induced triple point for interacting polymers
Sanjay Kumar, Debaprasad Giri, Somendra M. Bhattacharjee
We show the existence of a force induced triple point in an interacting polymer problem that allows two zero-force thermal phase transitions. The phase diagrams for three different…
Does a surface attached globule phase exist ?
Pramod Kumar Mishra, D. Giri, S. Kumar +1
A long flexible neutral polymer chain immersed in a poor solvent and interacting with an impenetrable attractive surface exhibits a phase known as surface attached globule ({\bf SA…
