Elasticity of single flexible polymer chains in good and poor solvents
Vikhyaat Ahlawat, Shatruhansingh Rajput, Shivprasad Patil
Force versus extension curves measure entropic elasticity of single polymer chain in force spectroscopy experiments. A Worm-like Chain model is used to describe force extension exp…

Elastic response of poly(ethylene glycol) polymer chains studied using dynamic atomic force microscopy
Vikhyaat Ahlawat, Shatruhan Singh Rajput, Shivprasad Patil
Stretching response of polymer chains under external force is crucial in understanding polymer dynamics under equilibrium and non-equilibrium conditions. Here we measure the elasti…
