Forces at the scale of the cell
K. Vijay Kumar, Mandar M. Inamdar, Pramod A. Pullarkat +1
The importance of molecular-scale forces in sculpting biological form and function has been acknowledged for more than a century. Accounting for forces in biology is a problem that…
Rotational dynamics of bound pairs of bacteria-induced membrane tubes
Makarand Diwe, P B Sunil Kumar, Pramod Pullarkat
We present experiments demonstrating tube formation in giant unilamellar vesicles that are suspended in a bath of swimming E. coli bacteria. We chose the lipids such that the bacte…
Steerable dual-trap optical tweezers with confocal position detection using back-scattered light
Md Arsalan Ashraf, Pramod Pullarkat
Optical tweezers has emerged as a powerful tool in manipulating microscopic particles and in measuring weak forces of the order of a pico-Newton. As a result, it has found wide app…
Investigation of Soft and Living Matter using a Micro-Extensional Rheometer
Sushil Dubey, Sukh Veer, Seshagiri Rao R +2
Rheological properties of a material often require to be probed under extensional deformation. Examples include fibrous materials such as spider-silk, high-molecular weight polymer…
Strain softening and stiffening responses of spider silk fibers probed using Micro-Extension Rheometer
Sushil Dubey, Chinmay Hemant Joshi, Sukh Veer +4
Spider silk possesses unique mechanical properties like large extensibility, high tensile strength, super-contractility, etc. Understanding these mechanical responses require chara…
The role of the cytoskeleton in volume regulation and beading transitions in PC12 neurites
Pablo Fernandez, Pramod A. Pullarkat
We present investigations on volume regulation and beading shape transitions in PC12 neurites conducted using a flow-chamber technique. By disrupting the cell cytoskeleton with spe…
