Iowa State awards grants to develop health, energy and research technologies

and measures forces; and fluorescence resonance energy transfer technology that observes single molecules at very high resolution.

Using one or the other technology is like "having hands but no eyes or eyes but no hands," said Sivasankar. "We can combine these two technologies into one instrument."

That makes a big difference in biological studies, Sivasankar said. Typically, biologists study samples made up of thousands of molecules. The resulting data describes the average molecule in the sample. He said the new instrument can reveal the individual characteristics of a molecule.

Sivasankar, who has been working to refine a prototype of the instrument, said the microscope is very useful in his own studies of how the cells of the body bind and organize themselves. He said the instrument could also be a powerful tool in biomedical research, drug discovery, cancer diagnostics and bio-sensing applications.

The other Iowa State projects to win 2010 grants from the Grow Iowa Values Fund are:

  • $117,944 to Ayman Fayed, assistant professor of electrical and computer engineering. He'll work with Rockwell Collins Inc. to develop switching power regulators that are appropriate for sensitive, portable communication and navigation devices. The new regulators would replace inefficient components and could double the battery life of the devices.

  • $109,243 to Vasant Honavar, professor of computer science and director of Iowa State's Center for Computational Intelligence, Learning and Discovery. He'll work with Collaborative Health Solutions LLC of Austin, Texas, to develop advanced algorithms and software tools for computer applications that can improve the quality and reduce the cost of health care.

  • $109,000 to Sri Sritharan, Wilson Engineering Professor of Civil, Construction and Environmental Engineering. He'll work with Iowa Prestressed Concrete of Des Moines, Clipper Windpower Inc. of Carpinteria, Ca
