Nanomanufacturing Using DNA Origami

Posted in Hardware on 8th Mar, 2012 06:56 PM by AlexMuller

In recent years, scientists have begun to harness DNA’s powerful molecular machinery to build artificial structures at the nanoscale using the natural ability of pairs of DNA molecules to assemble into complex structures. Such “DNA origami,” first developed at the California Institute of Technology,* could provide a means of assembling complex nanostructures such as semiconductor devices, sensors and drug delivery systems, from the bottom up.


While most researchers in the field are working to demonstrate what’s possible, scientists at the National Institute of Standards and Technology (NIST) are seeking to determine what’s practical.**


According to NIST researcher Alex Liddle, it’s a lot like building with LEGOs—some patterns enable the blocks to fit together snugly and stick together strongly and some don’t.


“If the technology is actually going to be useful, you have to figure out how well it works,” says Liddle. “We have determined what a number of the critical factors are for the specific case of assembling nanostructures using a DNA-origami template and have shown how proper design of the desired nanostructures is essential to achieving good yield, moving, we hope, the technology a step forward.”


In DNA origami, researchers lay down a long thread of DNA and attach “staples” comprised of complementary strands that bind to make the DNA fold up into various shapes, including rectangles, squares and triangles. The shapes serve as a template onto which nanoscale objects such as nanoparticles and quantum dots can be attached using strings of linker molecules.

Dec08 Thanks for the a new challenge you have ueocvernd in your article. One thing I'd prefer to touch upon is that FSBO connections are built eventually. By introducing yourself to the owners the first end of the week their FSBO is actually announced, ahead of masses commence calling on Mon, you generate a good relationship. By sending them tools, educational products, free accounts, and forms, you become the ally. If you take a personal fascination with them plus their circumstances, you generate a solid link that, oftentimes, pays off when the owners opt with an adviser they know and also trust preferably you actually.
