  • Third Frontier Funds YSI-UC Team
Apr 2010
CINCINNATI, April 13, 2010 — The Ohio Third Frontier Commission has approved a $1,127,873 award to YSI Inc. of Yellow Springs, Riehl Engineering Ltd. of Dayton and the University of Cincinnati (UC) for their “Advanced Modified Carbon Nanotube-Based Nutrient Sensor” project. The venture will produce an improved sensor to enable critical monitoring of environmental waters for nitrate, which is a major pollutant associated with wastewaters and agricultural runoffs. Sensors are devices used to collect information about an environment, either remotely or by being located in the area being studied.

The university’s Prof. William Heineman of the McMicken College of Arts & Sciences department of chemistry is officially part of the million-dollar team. “The carbon nanotube-based sensor will be able to measure the nitrate in an extremely fast, sensitive way,” he said. “The sensor will be a superior method of providing environmental quality control.”

Nitrate is a chemical compound commonly found in fertilizers and formed by microbes that break down nitrogen-bearing plant residues in the soil. Storm water runoff washes these nitrates into streams and rivers. Nitrate, being a nutrient, feeds algae and other plants in the water. Too much nitrate causes growth surges, thus choking out the fish and other animals.

Nitrates that might be entering a community’s drinking water must be monitored by industries as mandated by several requirements and regulations, such as National Pollutant Discharge Elimination System permits under the Clean Water Act, the Safe Drinking Water Act, and the Emergency Planning and Community Right to Know Act.

Up until now, such monitoring has been cumbersome, with sensors being approximately the size of a 45-gal can and weighing about 80 lbs. Thanks to the work of the team, the new sensors that are currently in development will be about one-third the size of a pencil, and will fit in a “smart probe” that is about the size of a AA flashlight. The team believes that this sensor will encourage many more industries — and perhaps even individuals — to monitor their runoff.

“Once you can do it, people will do it more,” said Kevin Schlueter, YSI’s program manager for the project. “A lot of companies have been asking for something like this.”

As part of the project, a Raman microscope worth more than a quarter of a million dollars will be purchased for the UC Sensor Instrumentation Laboratory. One UC graduate student will also be funded to work on this project.

“There will be a dual benefit,” said Heineman. “YSI will be able to use the instrument and my students and I will be able to use it as well.”

According to Heineman, there is a definite positive synergy to the project. “YSI wants products – I want projects for my PhD students. My job is to generate relevant research projects so that the students can learn how to do research. This grant enables them to help develop a sensor they wouldn’t have ordinarily have had access to,” he said. “An added benefit is the opportunity for my students to learn about industry by ‘rubbing elbows’ with YSI scientists working on this project.” UC chemistry has played a large role in the development of this particular product.

YSI’s Schlueter earned his PhD in Chemistry at UC while studying under Brian Halsall and he did his postdoctoral research under Heineman and Halsall. YSI’s Biosensor Technologies Director, Jay Johnson, is also a PhD graduate of UC’s Chemistry Department and a former student of Heineman’s. Ed King, Vice President of Research for YSI, did not go to UC, but he is another Ohio product, having graduated from Ohio Northern University.

“This is a good Ohio story,” King says. “Through the Third Frontier Grants, we’re proliferating goodwill and jobs throughout Ohio.”

Besides being of benefit to the communities of Ohio, the Ohio Third Frontier grants also support education and further business development in Ohio. Ohio’s Third Frontier program helped in the formation of about 14,000 direct and indirect jobs in the state in 2009 and nearly 55,000 direct and indirect jobs since the program’s inception in 2002.
