Northwestern researchers create state-of-the-art desktop nanofabrication tool A new low-cost, high-resolution tool is primed to revolutionize how nanotechnology is produced from the desktop, according to a new study by Northwestern University researchers. Currently, most nanofabrication is done in multibillion-dollar centralized facilities called foundries. This is similar to printing documents in centralized printing shops. Consider, however, how the desktop printer revolutionized the...

Artificial atoms and bonds provide a new set of building blocks for future materials Northwestern University's Chad A. Mirkin, a world-renowned leader in nanotechnology research and its application, has developed a completely new set of building blocks that is based on nanoparticles and DNA. Using these tools, scientists will be able to build -- from the bottom up, just as nature does -- new and useful structures. Mirkin will discuss his research in a session titled "Nucleic...

Design rules will enable scientists to use DNA to build nanomaterials with desired properties Nature is a master builder. Using a bottom-up approach, nature takes tiny atoms and, through chemical bonding, makes crystalline materials, like diamonds, silicon and even table salt. In all of them, the properties of the crystals depend upon the type and arrangement of atoms within the crystalline lattice. Now, a team of Northwestern University scientists has learned how to top nature by...

Synthetic PCR mimic could lead to highly sensitive medical, environmental diagnostics Northwestern University researchers have taken another step towards realizing a new class of polymerase chain reaction (PCR) enzyme mimics, opening the door for the development of highly sensitive chemical detection systems that go beyond nucleic acid targets. The blueprint for building synthetic structures to detect and signal the presence of targets such as small molecule medical analytes (signalers of...

Pens that write with light offer low-cost, rapid nanofabrication capabilities One Chicago skyline is dazzling enough. Now imagine 15,000 of them. A Northwestern University research team has done just that -- drawing 15,000 identical skylines with tiny beams of light using an innovative nanofabrication technology called beam-pen lithography (BPL). Details of the new method, which could do for nanofabrication what the desktop printer has done for printing and information transfer, will be...

New technology 300 times more sensitive than commercial tests, defines new PSA 'zero' A team of Northwestern University researchers, using an extremely sensitive tool based on nanotechnology, has detected previously undetectable levels of prostate-specific antigen (PSA) in patients who have undergone radical prostatectomy. The researchers found measureable PSA levels in each post-operative patient in its study, thanks to the power of the nanoparticle-based bio-barcode assay developed at...

Buttery Christmas cookies, eggnog, juicy beef roast, rich gravy and creamy New York-style cheesecake. Happy holiday food unfortunately can send blood cholesterol levels sky high.Northwestern University scientists now offer a promising new weapon -- synthetic high-density lipoprotein (HDL), the "good" cholesterol -- that could help fight chronically high cholesterol levels and the deadly heart disease that often results.The researchers successfully designed synthetic HDL and show that their...


Word of the Day
negawatt
  • A unit of saved energy.
Coined by Amory Lovins, chairman of the Rocky Mountain Institute as a contraction of negative watt on the model of similar compounds like megawatt.
