Reach out and touch an oscillator: Cornell researchers find a new way to read nanoscale vibrations
Nanomechanical oscillators — tiny strips of vibrating silicon only a few hundred atoms thick — are the subject of extensive study by nanotechnology researchers. They could someday replace bulky quartz crystals in electronic circuits or be used to detect and identify bacteria and viruses.   view more (2007-03-27)

'Nanocantilevers' yield surprises critical for designing new detectors
Researchers at Purdue University have made a discovery about the behavior of tiny structures called nanocantilevers that could be crucial in designing a new class of ultra-small sensors for detecting viruses, bacteria and other pathogens.   view more (2006-08-29)

Mechanical motion used to 'spin' atoms in a gas
For the first time, mechanical motion has been used to make atoms in a gas "spin," scientists at the National Institute of Standards and Technology (NIST) report.   view more (2006-12-11)

Growing nanostructures on micro cantilever provides new platform for materials discovery
Researchers have developed a new technique that could provide detailed information about the growth of carbon nanotubes and other nanometer-scale structures as they are being produced.   view more (2006-06-07)

Fast AFM probes measure multiple properties of biomolecules or materials simultaneously
New research demonstrates that novel probe technology based on flexible membranes can replace conventional atomic force microscopy (AFM) cantilevers for applications such as fast topographic imaging, quantitative material characterization and single molecule mechanics measurements.   view more (2008-04-17)

Purdue engineers solve chaos mystery in use of high-tech microscope
Mechanical engineers at Purdue University have proven that the same sort of "deterministic chaos" behind the baffling uncertainties of the stock market and long-term weather conditions also interferes with measurements taken with a commonly used scientific instrument.   view more (2006-01-20)

'Radio wave cooling' offers new twist on laser cooling
Visible and ultraviolet laser light has been used for years to cool trapped atoms-and more recently larger objects-by reducing the extent of their thermal motion.   view more (2007-09-17)

Bioengineers at University of Pennsylvania devise nanoscale system to measure cellular forces
University of Pennsylvania researchers have designed a nanoscale system to observe and measure how individual cells react to external forces.   view more (2007-08-28)

Tough new probe developed for nanotechnologists
Since the invention of the atomic force microscope (AFM) in 1986 by Nobel laureate Gerd Binnig, the tool has been employed to advance the science of materials in many ways, from nanopatterning (dip-pen nanolithography) to the imaging of surfaces and nano-objects such as carbon nanotubes, DNA,... view more (2005-08-11)

'World's smallest controlled heat source' studies explosives at the nanoscale
Using nanometer scale analysis techniques and quantities too small to explode, researchers have mapped the temperature and length-sale factors that make energetic materials - otherwise known as explosives - behave the way they do.   view more (2006-09-11)

Sharply-tuned nanostrings work at room temperature
Using a fast, low-cost fabrication technique that allows inexpensive testing of a wide variety of materials, Cornell researchers have come up with nanoscale resonators - tiny vibrating strings - with the highest quality factor so far obtainable at room temperature for devices so small.   view more (2006-07-17)
