Nano Electro-Mechanical Systems (NEMS) are tiny
machines built at the nanometer scale. Current
NEMS applications are simple machines, such as
the tiny cantilever shown at the right. An electrical circuit measures the deflection
of the lever. A larger version of this device,
with dimensions at the micrometer or millimeter
scale, is commonly used as an airbag sensor in
automobiles. A sudden stop causes a strong
deflection of the lever, which signals that
the airbags should be deployed. At the nano
scale, such a lever is sensitive enough to
measure the weight of individual atoms or
molecules resting upon it.

The Network for Computational Nanotechnology (NCN) held a workshop entitled Challenges and Opportunities in the Development of Nanoelectromechanical Systems on April, 8, 2005. The workshop was held at the Entrepreneurship Center at Purdue University and featured presentations and discussion on...
Single Electron Switching with Nano-Electromechanical Systems and Applications in Ion Channel Transport
01 Nov 2004 | | Contributor(s):: Robert H. Blick
Taking classes in physics always starts with Newtonian mechanics. In reducing the size of the objects considered however the transition into the quantum mechanical regime has to occur. The 'mechanics' of quantum mechanics is best studied in nano-structured semiconductor systems often termed...
Bioinformatics and Systems Biology: At the Crossroads of Biology, Engineering, and Computation
08 Oct 2004 |
Traditional biological research has relied on a "deconstructive" mode where piece-wise analysis of the components of complex systems was carried out in detail. The genome projects have spurred the discovery of new genes/molecules to add to the existing inventory of "parts" that make up living...
Computational Prototyping Tools For Biological Applications
03 Dec 2004 |
Computational tools are playing a rapidly expanding role in biology, both for engineering design and in exploratory science. The main reason is that the dramatic improvements in the measurement and mathematical modeling of basic biochemical and biological processes is making it possible to...
Construction of an Imitating Nano-motor Driven by Six ATP-binding RNAs of Bacterial Virus phi29
02 Dec 2004 |
A switchable imitating DNA-packaging motor was constructed in the laboratory. The motor is driven by six synthetic ATP-binding pRNA (packaging RNA) molecules that bind to the connector and function in a manner similar to the driving of a bolt with a hex nut. Conformational change and sequential...

Welcome to Nanotechnology 101, a series of lectures designed to provide an undergraduate-level introduction to nanotechnology. In contrast, the Nanotechnology 501 series offers lectures for the graduate-level and professional audiences.
Multiscale Modeling of the Mechanical Behavior of Polymer-Based Nanocomposites
25 Mar 2004 |
Polymers filled with nanoscale fillers (carbon nanotubes or nanoparticles) exhibit enhanced properties compared with the neat polymer and with the polymer filled with micron-sized fillers at same volume fraction. Most interestingly, combinations of exceptional properties may be obtained as, for...

Quantum Electromechanical Systems: Are we there yet?
05 Feb 2004 | | Contributor(s):: Andrew Cleland
Electrons moving in a conductor can transfer momentum to the lattice via collisions with impurities and boundaries, giving rise to a fluctuating mechanical stress tensor. Driving electrons out of equilibrium by applying the voltage across the conductor, one may control this electromechanical noise.
