Engineering Nanoscale Biological Molecular Motors

In his book ‘What is life?’, Erwin Schrödinger equated death with the living cell decaying into thermal equilibrium with its surroundings. That is, when a cell is unable to continue using the free energy of its environment to keep order, it decays into a state of disorder. Evolution has led to incredibly beautiful, complex, and astonishing constructs called molecular motors to maintain order an...

The physics of molecular motors.

Molecular motors convert chemical energy into mechanical force and movement. Operating at energies just above those of the thermal bath, these motors experience large fluctuations, and their physical description must be necessarily stochastic. Here, motor operation is described as a biased diffusion on a potential energy surface defined by the interactions of the motor with its track and its fu...

Engineering controllable bidirectional molecular motors based on myosin

Cytoskeletal motors drive the transport of organelles and molecular cargoes within cells and have potential applications in molecular detection and diagnostic devices. Engineering molecular motors with controllable properties will allow selective perturbation of mechanical processes in living cells and provide optimized device components for tasks such as molecular sorting and directed assembly...

Molecular physics of a polymer engineering instability: experiments and computation.

Entangled polymer melts exhibit a variety of flow instabilities that limit production rates in industrial applications. We present both experimental and computational findings, using flow of monodisperse linear polystyrenes in a contraction-expansion geometry, which illustrate the formation and development of one such flow instability. This viscoelastic disturbance is observed at the slit outle...
