DNA-binding strands used to create molecular zipper

30.03.2004


Virginia Tech students and faculty members are creating releasable coatings and thin films using the same chemistry that nature uses to bind the double helix of DNA.



They will present their research at the 227th national meeting of the American Chemical Society in Anaheim, Calif., March 28-April 1, 2004.

"We are coating a patterned surface with accepting molecules then applying donating molecules – that is, using molecular recognition -- to create a molecular zipper," explains Tim Long of Blacksburg, professor of chemistry in the College of Science at Virginia Tech.


Applications would be strong, multilayered structures that might be used for body armor, as well as for releasable coatings and films.

The researchers are using heterocycles – the same groups that bind strands of DNA. "They can be selected to recognize specific complementary groups based on the attributes desired," Long says.

The paper, "Multiple hydrogen bonding on surfaces (PMSE 135)," will be presented by Casey L. Elkins, a graduate student from Coopersville, Mich. Her co-authors are doctoral student Kalpana Viswanathan of Madras, India, Adhesive and Sealant Science Professor Thomas C. Ward of Blacksburg, Va., and Long. The presentation will be at 2:40 p.m. on Monday, March 29, at Coast Anaheim Hotel in the Park B room as part of the Division of Polymeric Materials: Science and Engineering symposium on Functional Polymer Thin Films for Switching, Sensing, and Adaptive Applications.

Elkins received her undergraduate degree from Michigan State University and Viswanathan received her master of science degree from Indian Institute of Technology, Madras.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...

Rice University researchers test 3-D carbon nanostructures' thermal transport abilities

Pillared graphene would transfer heat better if the theoretical material had a few asymmetric junctions that caused wrinkles, according to Rice University...
