Steerable optical nanoantennas light the way for practical lab-on-a-chip devices

By - February 25, 2015 1 Picture
Using unidirectional cubic nanoantennas to direct the output from nanoemitters, researchers at Monash University in Australia have described a method to accurately focus light at the nanoscale. The practical upshot of which is substantial progress towards guided, ultra-narrow beams needed for the new world of nanoelectromechanical systems (NEMS) and the eventual production of entire lab-on-a-chip devices.

Researchers break sensitivity record for mass measurement

By - May 20, 2012 2 Pictures
A sprocket of research engineers (yes, apparently that's the collective noun for a group of engineers) at the Catalan Institute of Technology (CIT) has succeeded in breaking the record for sensitivity of mass measurement. By measuring the resonant frequency of a short length of single carbon nanotube, masses as small as a single nucleon (proton or neutron), having a mass of about 1.7 yoctogram (1 yg = 10^-24 grams) were measured, thereby exhibiting a level of sensitivity several orders of magnitude better than previous devices. This new technology enables the detection and identification of individual atoms and molecules and tracing the fate of individual atoms in a chemical reaction. Read More

Tiny light mill could have big applications in nanotech

By - July 9, 2010 3 Pictures
OK, first of all, what’s a light mill? It’s a simple rotary motor consisting of four flat vanes mounted to a central axis, which spins when subjected to light. Light mills have been around since 1873, mostly just as novelty items, and have pretty much always been at least a few inches tall. Less than a week ago, however, scientists at California’s Lawrence Berkeley National Laboratory announced the creation of a light mill just 100 nanometers in size. Unlike its bigger brothers, this tiny device might actually have some very practical applications. Read More

Small liquid sensor could lead to home cancer detection kits

By - February 18, 2010 1 Picture
Just as home tests revolutionized the detection of pregnancy, a tiny sensor being developed at the University of Missouri (MU) could bring the benefits of home testing to the diagnosis a variety of diseases, including breast and prostate cancers. The sensor, known as an acoustic resonant sensor, is smaller than a human hair and could one day be used in home testing kits for the easy, rapid and accurate diagnosis of a range of diseases.

A nuclear battery the size and thickness of a penny

By - October 9, 2009 0 Pictures
They might sound dangerous, but nuclear batteries have been safely powering devices such as pace-makers, satellites and underwater systems for years. They have an extremely long life and high energy density compared to chemical batteries. However, they are costly and also very large and heavy. Now researchers at the University of Missouri (MU) are developing a nuclear battery that is smaller, lighter and more efficient. Read More
