DNA Origami Nanoscale Breadboards for Carbon Nanotube Circuits
Hareem T. Maune, a graduate student studying carbon nanotube physics, and Si-ping Han, a graduate student investigating the interactions between carbon nanotubes and DNA have developed DNA origami nanoscale breadboards for carbon nanotube circuits. "This collaborative research project is evidence of how we at Caltech select the top students in science and engineering and place them in an environment where their creativity and imagination can thrive," says Ares Rosakis, chair of the Division of Engineering and Applied Science at Caltech and Theodore von Kármán Professor of Aeronautics and Professor of Mechanical Engineering. The work of these students was supervised by: Erik Winfree, Associate Professor of Computer Science, Computation and Neural Systems, and Bioengineering; William A. Goddard III, Charles and Mary Ferkel Professor of Chemistry, Materials Science, and Applied Physics; Paul W.K. Rothemund, Senior Research Associate, and Marc Bockrath, Associate Professor of Physics at University of California Riverside. [Caltech Press Release]
Chiara Daraio Selected to Participate in the STS Forum - Future Leaders Initiative
Chiara Daraio, Assistant Professor of Aeronautics and Applied Physics, has been selected to participate in the 2009 Science & Technology in Society (STS) Forum - Future Leaders Initiative. Daraio will join nine other outstanding young scientists from Japan, England, Germany, Chile, Uruguay, Malawi, China and the United States to discuss the impact of their research on societal development. Daraio's research focuses on synthesizing and testing so-called "smart" materials that have a variety of potential applications, ranging from novel methods for sustainable engineering and nondestructive evaluation of civil and mechanical infrastructure (e.g., bridges, power plants) to new acoustic lenses for biomedical imaging and surgery.
The STS Forum is organized and sponsored by the Japan Society for the Promotion of Science (JSPS). Guruswami Ravichandran, director of the Graduate Aerospace Laboratories and John E. Goode, Jr. Professor of Aeronautics and Mechanical Engineering, said, "I am delighted that Dr. Daraio will be representing GALCIT and Caltech at this internationally renowned, interdisciplinary, and cross-sectoral forum". "Dr. Daraio's selection to participate in this world forum is yet another indication of the importance and far reaching impact of the research conducted by the engineering and applied science faculty", said Professor Ares Rosakis, chair of Caltech's Division of Engineering and Applied Science and Theodore von Kármán Professor of Aeronautics and Mechanical Engineering.
Michael Roukes and Akshay Naik Create First Nanoscale Mass Spectrometer
Michael L. Roukes, Professor of Physics, Applied Physics, and Bioengineering; Co-Director, Kavli Nanoscience Institute, and colleague Akshay Naik have created the first nanoscale mass spectrometer. This new technique simplifies and miniaturizes the measurement of the mass of molecules through the use of very tiny nanoelectromechanical system (NEMS) resonators. Askshay Naik explains, "the frequency at which the resonator vibrates is directly proportional to its mass. When a protein lands on the resonator, it causes a decrease in the frequency at which the resonator vibrates and the frequency shift is proportional to the mass of the protein". Professor Roukes points out, "the next generation of instrumentation for the life sciences must enable proteomic analysis with very high throughput. The potential power of our approach is that it is based on semiconductor microelectronics fabrication, which has allowed creation of perhaps mankind's most complex technology." [Caltech Press Release]
