The creation of nanometre-sized structures that exhibit controllable motions and functions is a critical step towards building nanomachines. Recent developments in the field of DNA nanotechnology have begun to address these goals, demonstrating complex static or dynamic nanostructures made of DNA. Here we have designed and constructed a rhombus-shaped DNA origami 'nanoactuator' that uses mechan...

The design hypothesis, architectures, and computational modeling of a novel peptide-based nanoactuator are presented in this paper. We engineered the -helical coiled-coil portion of the yeast transcriptional activator peptide called GCN4 to obtain an environmentally responsive nanoactuator. The dimeric coiled-coil peptide consists of two identical approximately 4.5 nm long and approximately 3 n...

A multi-walled carbon nanotube (MWNT) bimorph nanoactuator has been modeled, fabricated and characterized. A thin aluminum film was uniformly deposited on the sidewalls of MWNTs using a pulsed laser deposition method to create the bimorph nanostructure. For a temperature change from 290 to 690 K with measured dimensions of 100 +/- 20 nm for the MWNT diameter, 40 +/- 10 nm for the Al thickness, ...

This paper studies the nonlinear behavior of a nano-optomechanical actuator, consisting of a free-standing arc in a ring resonator that is coupled to a bus waveguide through evanescent waves. The arc deflects when a control light of a fixed wavelength and optical power is pumped into the bus waveguide, while the amount of deflection is monitored by measuring the transmission spectrum of a broad...

A DNA-based molecular machine is described which has two movable arms that are pushed apart when a strand of DNA, the fuel strand, hybridizes with a single-stranded region of the molecular machine. Through the process of branch migration, a second strand of DNA complementary to the fuel strand is able to remove the fuel strand from the molecular machine, restoring it to its original configurati...

We report on three new types of nanoelectromechanical systems based on carbon nanotubes: an electromechanical nanothermometer, a nanorelay and a nanomotor. The nanothermometer can be used for accurate temperature measurements in spatially localized regions with dimensions of several hundred nanometers. The nanorelay is a prototype of a memory cell, and the nanoactuator can be used for transform...
