“Starting as an ASU assistant professor just a decade ago, Hao Yan has had a meteoric rise through the academic ranks of ASU and thrived in the multi-disciplinary atmosphere of the Biodesign Institute,” said Raymond DuBois,  executive director of the Biodesign Institute. “With his impressive body of work, extraordinary talents of the research team he has assembled and the breakneck speed of their discoveries and achievements, he has had a profound impact on nanotechnology. Now, with the expansion of Hao Yan’s research in the establishment of this new center, and the recruitment of more top-notch talent, we will significantly broaden the scope and influence of his research.”

The new center becomes the 12th research center at ASU’s Biodesign Institute and is emblematic of the institute’s mission of scientists tackling complex societal issues by creating “bio-inspired” solutions to some of the world’s most urgent challenges in the areas of biomedicine and health outcomes, sustainability and national security.

“Now, with this center, there is a golden opportunity to expand ASU’s research in molecular design and biomimicry,” said Yan, who holds the inaugural Milton Glick Distinguished Professor of Chemistry and Biochemistry. “I am thankful to President Crow and ASU’s leadership for the opportunity to implement the vision of this new center and develop a world-class biomimicry effort to benefit ASU, the state and ultimately society.”

Imitation of life

In nature’s role as Earth’s master architect, an almost 4 billion-year trial-and-error process has refined all of our planet’s living organisms, functions and materials. Scientists have long looked at nature as inspiration for answers to both complex and simple problems throughout our existence, from Leonardo Da Vinci creating elaborate sketches of flying machines by studying birds in flight to more recent attempts to understand the properties of spiders’ silk to build materials as strong as Kevlar. The field of biomimicry has given rise to new technologies created from biologically-inspired engineering, ranging from nano-scale to macro-scale outcomes.

To date, Yan’s research approach has focused on using DNA, an essential building block of all life forms, as the architectural underpinnings of a biomimicry approach to advanced nanotechnology with the ultimate goal of building a suite of dynamic nanoscale devices.

Yan is a well-recognized leader in his field, known as structural DNA nanotechnology, or DNA origami, that can fold and self-assemble DNA into a broad range of technological applications important for human health and bio-electronic sensing devices. In addition to his research team’s scientific achievements that have graced the covers of leading research journals such as Science and Nature, honors for Yan include a $6.5 million Department of Defense MURI award; an Alfred P. Sloan Research Fellowship (2008-10); National Science Foundation CAREER Award (2006-2011); Air Force Office of Scientific Research Young Investigator Award (2007-2010); and the Arizona Technology Enterprise Innovator of Tomorrow Award (2006).

Yan’s inspiration behind the new biomimicry center is to move beyond DNA nanotechnology and develop innovative technologies that may spark a ‘bottom up’ nanotechnology industry to develop novel solutions in medicine, energy and electronics. Such a field could spawn the growth of entirely new 21st century industries.

“I have always been very interested in designer architecture,” said Yan. “Every architect needs a set of design rules. In nanotechnology, we need a set of rules that will allow anyone in the field to be able to design an engineered biochemical pathway using a bottom-up approach, where we use the biochemical building blocks of a cell as our building blocks to make new discoveries.” 

From bio-inspiration to innovation

Yan’s research team has built a variety of 2-D and 3-D structures at a scale 1,000 times smaller than a human hair, and now, he wants to push their efforts to build even smaller, and design at the scale of individual atoms, molecules and chemical bonds, which he has dubbed “Angstrom level control.”

Support for the establishment of the center includes federal funding and funds from ASU’s Office of Knowledge Enterprise Development. As the center grows and matures, large collaborative grants with other universities and industrial partnerships will serve to accelerate discovery.

Major Center for Molecular Design and Biomimicry research thrusts include developing faculty labs devoted to all aspects of the biomimetic innovation cycle, including:

• Design – employing computational methods to design, model and predict molecular behavior

• Synthesis – making the building blocks and molecular “Lego” sets

• Assembly – assembling building blocks into structures

• Programming – thinking of biomimetic systems like the transistors, circuits and logic found in microprocessors and computer hardware

• Biomimetic materials and systems engineering – integrating biomimetic materials with man-made systems to optimize functionality

“Our initiative will ultimately distinguish itself significantly from the majority of other biomimicry efforts around the world, where scientists develop biomimetic materials by identifying, adapting and modifying existing biological components for subsequent integration with man-made materials,” said Yan. “Our vision is to design intelligent materials and processes, and a suite of smart molecules that can self-assemble into materials or function in biological networks to deliver drugs, control chemical reactions or build molecular scale electronics, as well as for tissue engineering, biosensors and renewable fuels."

NSF, ASU inspiring kids to 'change the world'


October 15, 2013

Across America, interest in science, technology, engineering and math (STEM) fields and degrees is dwindling. Students often shy away from STEM courses as early as elementary school, leaving the educational system in need of opportunities to inspire and engage more interest in these areas.

In an effort to increase awareness of STEM careers in today’s youth, the National Science Foundation and Congressman Frank Wolf organized the “Change the World: Science and Engineering Careers Fair” at the Dulles Town Center Mall in Virginia on September 27-28. Arizona State University’s Decision Center for a Desert City was invited by the National Science Foundation and Congressman Wolf to participate in the fair. Download Full Image

Wolf said that currently in the United States, there are half the number of graduating physicists as there were in 1956 and most of today’s STEM graduates come from foreign countries who return home, taking their knowledge with them.

Decision Center for a Desert City, an initiative under ASU’s Global Institute of Sustainability, conducts water, climate and decision-making research to develop boundary-breaking methods that foster a sustainable future. Its education coordinators partner with local K-12 teachers to develop interactive and engaging ways of presenting the center's work to young students.

“It is vital to expose students in STEM research at an early age to inspire their love of science, improve their confidence in their own ability to pursue education in STEM fields and show them how research and modeling can help improve their lives and the lives of friends and family,” says Dave White, co-director of the center, senior sustainability scientist in the Global Institute of Sustainability and associate professor in the School of Community Resources and Development.

The Dulles Town Center Mall was transformed over the weekend with stands and tables from over 100 exhibitors, like Decision Center for a Desert City, National Oceanic and Atmosphere Administration, National Weather Service, NASA Education, U.S. Geological Survey, National Science Foundation and ASU’s Quantum Energy and Sustainable Solar Technologies Engineering Research Center.

“This event provided an opportunity to educate the future citizens, scientists and engineers who will lead society in developing solutions to pressing sustainability problems,” White says.

Decision Center for a Desert City program manager Liz Marquez and graduate student Rashmi Krishnamurthy represented the center at the fair to demonstrate the mobile version of WaterSim, the center's water simulation system used to explore the future of water supplies in central Arizona based on factors like climate change, population growth, drought and policy changes.

“Interested students walked up to WaterSim and exclaimed, ‘What is this?’” Marquez says. “The students and their parents visualized the outcomes of their water use by running simulations of their indoor and outdoor water use. This allowed them to personalize the science.”

WaterSim can be accessed online and implemented in any educational setting.

“Students provided valuable feedback to help us improve the model for use in classrooms across the country,” White says. “Their input will be instrumental as we continuously update the model to improve the usability and relevance of WaterSim for K-12 education.”

Today’s environmental and societal problems are in dire need of future engineers, doctors, technicians and scientists. Fortunately, at the fair, these future leaders gained a first-hand impression of who they could be when they grow up. 

The center would also like to thank fair supporters David Sampson, Decision Center for a Desert City research scientist; Ray Quay, center director of stakeholder relations; Peggy Nelson, center co-principal investigator and education program coordinator; Monica Elser, education program coordinator; Erik Johnston, associate professor in the School of Public Affairs and director of Center for Policy Informatics.
