OcuCheck has not yet been tested on samples from trauma patients, Pan said.
"But we have mixed the samples with blood, and the sensor's sensitivity to ascorbic acid is retained even in the presence of blood. The filter paper will filter out the blood," he said.
"This technology has the ability to impact a large number of patients, particularly in rural settings, where access to an ophthalmologist can be limited," Labriola said.
The team is working with an industrial design professor at Illinois to build a housing for the sensor that will be portable and easy to use, Pan said. Pan and Labriola have founded a new company, InnSight Technology, to help them bring the device to market. The company has obtained a phase I Small Business Innovation Research grant from the National Science Foundation.
"This is a perfect example of physicians and engineers working together to find solutions to current problems in health care," Pan said, referring to the Carle Illinois College of Medicine, a new engineering-based medical college soon to be established on Illinois' Urbana-Champaign campus.
