Powering nanodevices with biomolecular motors.
Biomolecular motors, in particular motor proteins, are ideally suited to introduce chemically powered movement of selected components into devices engineered at the micro- and nanoscale level. The design of such hybrid "bio/nano"-devices requires suitable synthetic environments, and the identification of unique applications. We discuss current approaches to utilize active transport and actuatio...
متن کاملProcessivity and collectivity of biomolecular motors extracting membrane nanotubes.
Biomolecular motors can pull and viscously drag membranes. The resulting elongations include cell protrusions, tether networks, and sensorial tentacles. Here we focus on the extraction of a single tube from a vesicle. Via a force balance coupled to binding kinetics, we analytically determine the phase diagram of tube formation as function of the motor processivity, the surface viscosity of the ...
متن کاملA mechanochemical theory for the ATP-fuelled biomolecular motors
Biomolecular motors are normally single or complex biomolecules exerting mechanical forces over molecular and cellular scales. The ATP-fuelled biomolecular motors can transduce the chemical energy from ATP hydrolysis into forces and motions in cells. In biomolecular motors, transport reactions are both stoichiometric and enzymatic. We outline a mechanochemical theoretical framework for biomolec...
متن کاملTransportation of Micromachined Structures by Biomolecular Linear Motors
We have demonstrated a novel micro/nano transportation system using the adenosine triphosphate (ATP)-driven biomolecular motors. Two kinds of linear biomolecular motor systems, microtubulekinesin [1] and actinmyosin [2], are investigated as driving mechanisms in the system. The rail molecules, microtubules, and actin are patterned on a glass substrate using a regular soft lithography technique ...
متن کاملBiomolecular motors at the intersection of nanotechnology and polymer science
The dynamic cytoskeletal components, biomolecular motors and their associated filaments, can be integrated in vitro with synthetic components to enable nanoscale transport systems. These “molecular shuttles” have generated significant scientific interest over the past decade, resulting in over 200 publications. This review focuses on the contributions involving the use of linear biomolecular mo...
