Remember Slinky®, the coiled metal spring that "walks" down stairs with just a push, momentum and gravity? Researchers at the National Institute of Standards and Technology (NIST) have developed their own version of this classic–albeit 10 million times smaller–as a novel technology for manipulating and measuring DNA molecules and other nanoscale (billionth of a meter) materials. In the first of two recent papers, Samuel Stavis, Elizabeth Strychalski and colleagues...

It's not often that someone can claim that going from a positive to a negative is a step forward, but that's the case for a team of scientists from the National Institute of Standards and Technology (NIST) and private industry. In a recent paper, the group significantly extended the reach of their novel microfluidic system for analyzing the chemical components of complex samples. The new work shows how the system, meant to analyze real-world, crude mixtures such as dirt or whole blood, can...

The goal of an integrated, miniaturized laboratory analysis system, also known as a "lab-on-a-chip," is simple: sample in, answer out. However, researchers wanting to use these microfluidic devices to analyze complex solutions containing particulates or other contaminating materials often find that the first part of the process isn't so easy. Effective sample preparation from these solutions can be laborious, expensive and time-consuming, involving complicated laboratory methods that must be...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
