New UC sensor promises rapid detection of dangerous heavy metal levels in humans
Date:8/1/2011

where access to a certified metals lab is limited. Our sensor will only require about two droplets of blood serum and will provide results in about ten minutes. It's portable and usable anywhere."

Papautsky, UC associate professor of electrical and computer engineering, is co-author of the Biomedical Devices-published research, "Lab-on-a-Chip Sensor for Detection of Highly Electronegative Heavy Metals by Anodic Stripping Voltammetry." Other co-authors are Erin Haynes, assistant professor of environmental engineering; William Heineman, distinguished research professor of chemistry; and just-graduated electrical and computer engineering doctoral student Preetha Jothimuthu, just-graduated chemistry doctoral student Robert Wilson, and biomedical engineering undergraduate research co-op student Josi Herren.

FIRST FIELD TEST OF SENSOR EXPECTED IN 2012 IN MARIETTA, OHIO

One specific motivation for developing the sensor was an ongoing project by UC's Erin Haynes, who is studying air pollution and the health effects of manganese and lead in Marietta, Ohio. Manganese is emitted in that area because it is home to the only manganese refinery in the United States and Canada. Preliminary results from UC's Mid-Ohio Valley Air Pollution Study (M.A.P.S.) found elevated levels of manganese in Marietta residents when compared to those who live in other cities.

HOW THE UC SENSOR WORKS

The new UC sensor uses a technology called anodic stripping voltammetry that incorporates three electrodes: a working electrode, a reference electrode and an auxiliary electrode.

A critical challenge for such sensors is the detection of electronegative metals like manganese. Detection is difficult because hydrolysis, the splitting of a molecule into two parts by the addition of a water molecule, at the auxiliary electrode severely limits a sensor's ability to detect an electronegative metal.

To resolve this challenge, the UC team develo
