The mode-dependent dynamics of nonlinear nanomechanical resonators
… -- even when the dynamics are driven by the Brownian force. This nonlinearity has imposed a mechanical noise floor on the linear frequency measurements made in sensing applications. Given that NEMS also become more sensitive as they become smaller, this floor has resulted in a complex …

Direct numerical simulations and experimental investigation of dielectrophoresis
… field. The translatory motion occurs because a force called the dielectrophoretic force, which depends on the spatial variation of the electric field, acts on the particles. As the generation of force involves no moving parts and the particles can be moved without touching them, …

The driven and stochastic dynamics of micro and nanoscale cantilevers in viscous fluid and near a solid boundary
… simulations of the cantilever response to a force impulse. It is found that the driven dynamics depend upon the type of actuation in addition to the quantity measured. A comparison of the driven dynamics to the corresponding stochastic dynamics yields insight into the nature of the Brownian …

Dynamics of single semiflexible filaments in a viscous fluid
… and accounts for hydrodynamic as well as Brownian forces. This is tested against theoretically known and experimentally verified equilibrium properties and scaling laws. We then focus on flow fields commonly observed in microfluidic devices, particularly the dynamics of bio-polymers in …
