About
Bidirectional Linear Nanoactuator Powered by Biomolecular Motors Nanoscale engineering by humans can be greatly enhanced by the assimilation of biological specialization already achieved through natural evolution and by envisioning additional modifications through molecular genetics. Increasing the demand for in situ characterization and the quantification of samples in complex systems has stimulated the development of miniaturized chemical analysis systems that automatically perform multiple steps such as sampling, transport, separation and detection. Applications This technology can be used in nanoscale mechanical devices to pump fluids, open and close valves, provide translational movement, etc. Advantages Represents a major step forward in nanoscale engineering Provides a mean to control motor movement direction The hydrophobic sealing isolates the ATP solution, which opens the possibility for motor application in non-aqueous environments Technology Critical to chemical analysis systems is the availability of nano-mechanical devices that provide the necessary locomotive factors. FSU researchers have developed a bidirectional linear nanoactuator powered by biomolecular motors. The device is composed of two major components: a metal rod (transmission) coated with myosin and a well structure (fuel tank) with two heater stripes (switch). Here, the heater lines are coated with actin filament patterns with opposite polarities. The nanorod will be assembled onto the ATP well and the well will be filled with ATP solution.
