Using molecules of DNA like an architectural scaffold, Arizona State University scientists, in collaboration with colleagues at the University of Michigan, have developed a 3-D artificial enzyme cascade that mimics an important biochemical pathway that could prove important for future biomedical and energy applications.
The findings were published in the journal Nature Nanotechnology. Led by ASU Professor Hao Yan, the research team included ASU Biodesign Institute researchers Jinglin Fu, Yuhe Yang, Minghui Liu, Professor Yan Liu and Professor Neal Woodbury along with colleagues Professor Nils Walter and postdoctoral fellow Alexander Johnson-Buck at the University of Michigan.
Researchers in the field of DNA nanotechnology, taking advantage of the binding properties of the chemical building blocks of DNA, twist and self-assemble DNA into ever-more imaginative 2- and 3-dimensional structures for medical, electronic and energy applications.
In the latest breakthrough, the research team took up the challenge of mimicking enzymes outside the friendly confines of the cell. These enzymes speed up chemical reactions, used in our bodies for the digestion of food into sugars and energy during human metabolism, for example.
"We look to Nature for inspiration to build man-made molecular systems that mimic the sophisticated nanoscale machineries developed in living biological systems, and we rationally design molecular nanoscaffolds to achieve biomimicry at the molecular level," Yan said, who holds the Milton Glick Chair in the ASU Department of Chemistry and Biochemistry and directs the Center for Molecular Design and Biomimicry at the Biodesign Institute.
With enzymes, all moving parts must be tightly controlled and coordinated, otherwise the reaction will not work. The moving parts, which include molecules such as substrates and cofactors, all fit into a complex enzyme pocket just like a baseball into a glove. Once all the chemical parts have found their place in the pocket, the energetics that control the reaction become favorable, and swiftly make chemistry happen. Each enzyme releases its product, like a baton handed off in a relay race, to another enzyme to carry out the next step in a biochemical pathway in the human body.
For the new study, the researchers chose a pair of universal enzymes, glucose-6 phosphate dehydrogenase (G6pDH) and malate dehydrogenase (MDH), that are important for biosynthesismaking the amino acids, fats and nucleic acids essential for all life. For example, defects found in the pathway cause anemia in humans. "Dehydrogenase enzymes are particularly important since they supply most of the energy of a cell", said Walter. "Work with these enzymes could lead to future applications in green energy production such as fuel cells using biomaterials for fuel."

Engineers have been developing nanotechnology that could put tiny sensors in just about any material imaginable. Some of these sensors could be woven into clothing to save soldiers from chemical weapons, monitor vital signs from a Band-Aid, or make solar panels more efficient.
Making such small devices is labor intensive, so they are expensive to produce. Mass manufacturing flat, flexible sensors would reduce the cost, says University of Massachusetts Amherst chemical engineer Jim Watkins. He and his team at the NSF Center for Hierarchical Manufacturing are working on a roll-to-roll process to manufacture printable coatings.
You can have something that both performs better and is less expensive. Thats really the heart of nanomanufacturing, Watkins said.
Science correspondent Miles OBrien explains how these future assembly lines work in the National Science Foundations series Science Nation.*

NSFs Center for Hierarchical Manufacturing proves good test bed for large-scale nanomanufacturing designs Theres no shortage of ideas about how to use nanotechnology, but one of the major hurdles is how to manufacture some of the new products on a large scale. With support from the National Science Foundation (NSF), University of Massachusetts (UMass) Amherst chemical engineer Jim Watkins and his team are working to make nanotechnology more practical for industrial-scale manufacturing.
One of the projects theyre working on at the NSF Center for Hierarchical Manufacturing (CHM) is a roll-to-roll process for nanotechnology that is similar to what is used in traditional manufacturing. Theyre also designing a process to manufacture printable coatings that improve the way solar panels absorb and direct light. Theyre even investigating the use of self-assembling nanoscale products that could have applications for many industries.
New nanotechnologies cant impact the U.S. economy until practical methods are available for producing products, using them in high volumes, at low cost. CHM is researching the fundamental scientific and engineering barriers that impede such commercialization, and innovating new technologies to surmount those barriers, notes Bruce Kramer, senior advisor in the NSF Engineering Directorates Division of Civil, Mechanical and Manufacturing Innovation (CMMI), which funded the research.
The NSF Center for Hierarchical Manufacturing is developing platform technologies for the economical manufacture of next generation devices and systems for applications in computing, electronics, energy conversion, resource conservation and human health, explains Khershed Cooper, a CMMI program director.
The center creates fabrication tools that are enabling versatile and high-rate continuous processes for the manufacture of nanostructures that are systematically integrated into higher order structures using bottom-up and top-down techniques, Cooper says. For example, CHM is designing and building continuous, roll-to-roll nanofabrication systems that can print, in high-volume, 3-D nanostructures and multi-layer nanodevices at sub-100 nanometer resolution, and in the process, realize hybrid electronic-optical-mechanical nanosystems.

Making Nanotechnology More Practical For Industrial-scale Manufacturing
9 hours ago by Miles O'brien Made to order, a phrase that began with the service industry, is now vital to manufacturing's future. Manufacturing production has recently grown at its fastest pace in more than a decade, creating more economic value per dollar spent than any other sector. Adding to this surge is customization--the ability to quickly and efficiently make what you want when you want it. Rapid, efficient customization is becoming a reality for high-tech engineers, students and "maker" enthusiasts. Credit: NBC Learn, U.S. Patent and Trademark Office, and National Science Foundation

The poem, "In Praise of Air," by Sheffield's Simon Armitage is printed on a university building hoarding to emphasise its titanium dioxide coating is absorbing vehicle emissions that cause asthma and pollute our cities; Credit Air Quality News
Titanium dioxide coating on cars and aircraft have revolutionised protective nanotechnology. The University of Sheffield has set the target as absorbing the poisonous compounds from vehicle exhausts. Tony Ryan is the professor of physical chemistry in charge of adapting self-cleaning window technology to pollution solutions. The 10m x20m poster they now use on the Alfred Denny university building demonstrates how nitrogen oxides from 20 cars per day could be absorbed efficiently by roadside absorption.
The Prof has already demonstrated how jeans could have the titanium dioxide integrated in their fabric to clean up the city. The name of the miniscule nanoparticles of the commercial product is Catcio. During daylight, the photons of light inter-react with oxygen, releasing its atoms to form peroxide that will immediately wipe up the nitrogen compounds. Fairly complex, but simple for the chemicals involved! It's estimated that 80% of the pollution would be removed by clothing.
The great surface area of a hoarding can contribute similarly effective action against pollutants. London is now famed for the amount of nitrogen oxides that emerge from its burgeoning diesel traffic. This partly explains Britain's great problem with young asthma sufferers. They have the highest number of asthma patients in Europe. As Prof. Ryan states, "The science behind this is an additive which delivers a real environmental benefit that could actually help cut disease and save lives. "
The field of Soft Nanotechnology moves in devious ways with natural and artificial fabrics. Titanium of course is expensive, with this hoarding costing 100 extra to have the coating. The air-scrubbing poster is a new innovation that has to be placed alongside busy roads to do its job. Clothing worn on city streets is already (harmlessly) producing the compounds that will remove some vehicle pollutants. Next steps of course would involve removing the trucks and cars from city centres!

It sounds like a wonderful dream, but UltraTech's coating being tested on cars can repel water, dirt, and oil, cutting down on the number of trips you have to take to the car wash.
NISSAN This Nissan Versa Note would normally require a lot of scrubbing down after a muddy drive like this, but the carmaker and UltraTech are testingUltra-Ever Dry coating on vehicles to see how it repels water, dirt, and mud.
Not many people would confuse the sporty Nissan Versa Note with a commercial cement truck, but the two vehicles could have something in common one day: Special nano-coating that prevents water, dirt, fine oils, and even wet concrete from sticking to the car's surface. This new self-cleaning superhydrophobic technology may not entirely eliminate trips to the car wash, but it could mean that you'll go a year between visits.
Nissan engineers are testing UltraTech's Ultra-Ever Dry coating on a Nissan Versa Note at Nissan Technical Centre Europe under many conditions. Ultra-Ever Dry protects the Nissan from rain, spray, frost, sleet, and standing water. Ultra-Ever Dry may become an aftermarket option for the carmaker.
Ultra-Ever Dry has been a great help to the construction industry where it's being used to coat cement trucks, making them much easier to clean, says Mario Cruz, UltraTech's marketing manager.
In testing, UltraTech and Nissan are using a white car because Ultra-Ever Dry is opaque and "whitish translucent," according to Cruz. The coating doesn't have a glossy shine like the one left after hours with a can of wax and a chamois because the finish appears matte flat.
A surface treated with Ultra-Every Dry is more hydrophobic than wax or even water-resistant windshield coating, so it better repels water. The Ultra-Ever Dry coating will only last for about a year before it will have to re-applied depending upon weather conditions. Don't expect to use it on tires or upholstery, Cruz says: "It will wear off from abrasion."
UltraTech CEO Mark Shaw showed off the coating technology during a 2013 TED Talk. Nanoparticles coat the surface making a texture with patterns of geometric shapes that have "peaks" or "high points". These teeny-tiny high points repel water, some oils, wet concrete, and other liquids.
If you're thinking you'd love some Ultra-Ever Dry for your car, kitchen floor, snow shovel, kennel or garage, you're out of luck--it's only available for industrial use at this point. Cruz says that only a professional with the right equipment can apply the material to surfaces.

Newswise Troy, N.Y. Xing Wang, a biochemist investigating the bio-nanotechnology potential of DNA and RNA, has been appointed as an assistant professor in the Department of Chemistry and Chemical Biology at Rensselaer Polytechnic Institute. Wang joins Rensselaer from the University of South Florida, where he served as an assistant professor.
Xings research offers broad promise in drug delivery, bio-imaging, as a platform for research, and for other therapeutics and diagnostics, said Laurie Leshin, dean of the School of Science. We are thrilled he is joining the School of Science, and we welcome him to Rensselaer.
DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are familiar to us as the molecules that encode and transcribe the genetic instructions for building and sustaining all living organisms. Both DNA and RNA are composed of simple units called nucleotides that function as modular units, strung together in a genetic code much as dots and dashes are strung together in Morse code. Wangs research seeks to repurpose the modular nucleotides as building blocks for self-assembled nanoscale (one billionth of meter) structures and machinery.
DNA and RNA have a lot of advantages as bio-nanotechnology materials, said Wang. Among the advantages, DNA and RNA are bio-compatible, they can be readily synthesized or cloned, the rules that govern the interactions between nucleotides are highly predictable, and chemical properties of nucleotides are easily modified using current lab techniques.
In previous research, Wang investigated programming sequences of DNA strands that can self-assemble into two- or three-dimensional structures.
You can draw something on paper, a two- or three-dimensional structure, and then you can program sequences of DNA strands that will form your design, said Wang. Currently, this design process can even be assisted by semi-automated computer programs.
Self-assembled DNA nanostructure can serve as a prototyping breadboard to study the interactions of elements such as proteins, drugs, nanoparticles, or semiconducting quantum dots attached to the platform. A similar platform might serve as a sort of circuit board for nanoparticles aligned to form an electrical device. DNA might also be used in a drug delivery system, designed to enclose and protect a drug as it travels in the body, and bind to molecular receptors found only on the drug target.
Wang also researches RNA, which uses a slightly different set of nucleotides. Interactions among RNA chains are more complex than those among DNA chains.
