For years, scientists have known that the culprit is a single molecule, an enzyme that cuts proteins in two specific places.
's (nasdaq: IMCL - news - people ) Erbitux work by picking a single molecule and disabling it.
Oscillo is so diluted that there is essentially zero chance that even a single molecule of the original extract is in the product.
Pacific Biosciences of California, Inc. is engaged in the development, manufacture and commercialization of its single molecule, real-time, or SMRT technology-an integrated platform for genetic analysis.
The IBM team's innovation to create the first single molecule picture, of a molecule called pentacene, was to use the tip to pick up a single, small molecule made up of a carbon and an oxygen atom.
BBC: Atomic bond types discernible in single-molecule images
It's not well-known or even thought about but ever since Leo Hendricks unveiled the first fully synthetic moldable hard plastic called Bakelite to the American Chemical Society in 1909, except for a very small percentage that has been incinerated, every single molecule of plastic ever manufactured still exists somewhere in our environment.
The laser detectors on the machines aren't sensitive enough to see a single DNA molecule.
Its machine is due in early 2011 and will be the first to scan a single DNA molecule.
U.S. Genomics is even more ambitious: It hopes to develop a machine that can directly read a single DNA molecule.
That's just wide enough for a single DNA molecule to slip through.
His team is working on many next-generation technologies that could render Ion Torrent obsolete, including one that will read a single DNA molecule.
The same team took the first-ever single-molecule image in 2009 and more recently published images of a molecule shaped like the Olympic rings.

The IBM team's quantum computer was a straw-thin vial filled with a rust-colored liquid packed with millions of copies of a single organic molecule.
That's wide enough for a single DNA molecule to slip through.
Other members of my laboratory will use techniques such as force spectroscopy and single-molecule assays to further investigate the compounds that I screen, providing a more complete picture of the actions of these compounds.
Last year Hewlett-Packard, along with a team of scientists from UCLA, proved the ability to make a switch that could be turned off and on, like a transistor, out of a single organic molecule called a catenane.
The long-awaited era of single-molecule DNA sequencing will begin in earnest with new machines from companies like Pacific Biosciences, and with a bit of luck this will improve the speed at which we can recognise unknown bugs.
Last year Hewlett-Packard, along with a team of scientists from UCLA, proved that it is possible to make a switch that can be turned off and on, like a transistor, out of a single organic molecule called a catenane.
The message itself is copied into a single-stranded messenger molecule which carries it to the protein-making parts of the cell, where it is translated.
Scientists have used chromophores for decades to detect chemicals, but, until Fido, they weren't sensitive enough to detect trace explosives because each molecule of TNT vapor would switch off just a single chromophore, with the result that faint wisps of evil chemicals caused no visible change in luminosity.
After tinkering for a few weeks, Howard realized he could stabilize the molecule (and thus eliminate the toxicity problem) by adding a single chlorine atom.
GM--its market share dropping like a heavy molecule, its bonds near junk, its vehicles piling up in dealer lots-is making its single biggest research bet on developing a hydrogen-powered car.
