A Theoretical Method to determine unstressed off-rate from multiple bond force spectroscopy
(Elsevier B.V, 2012-06-15)Using dynamic force spectroscopy to measure the kinetic off-rates of intermolecular bonds currently requires the isolation of single molecules. This requirement arises in part because no tractable analytic method for ... -
Effect of Viscoelasticity on the Analysis of Single-Molecule Force Spectroscopy on Live Cells
(Elsevier Inc, 2012-07-03)Single-molecule force spectroscopy is used to probe the kinetics of receptor-ligand bonds by applying mechanical forces to an intermediate media on which the molecules reside. When this intermediate media is a live cell, ... -
Elastic capsule deformation in general irrotational linear flows
(IOP Publishing Ltd, 2012-07-05)Knowledge of the response of elastic capsules to an imposed fluid flow is necessary for predicting the deformation and motion of biological cells and synthetic capsules in microfluidic devices and in microcirculation. ... -
