Engineering team invents lab-on-a-chip for fast, inexpensive blood tests
Date:1/10/2011

is estimated that those numbers have quadrupled since then.

Faghri said that additional cartridges can be designed to detect biomarkers of other diseases. The researchers are already working to engineer the device to detect levels of the beta amyloid protein that can be used as a predictor of Alzheimer's disease. The device can also be engineered to detect virulent pathogens, including HIV, hepatitis B and H1N1 (swine) flu.

The next generation of the device will incorporate a hand-held sensor that will reduce manufacturing costs. Faghri also envisions a further miniaturization of the invention that can be adapted as a smartphone application. By embedding the biosensor in the cartridge and using the computer power of the phone, as well as its wireless communication capabilities, Faghri believes that patients may be able to conduct the tests themselves and have the results transmitted immediately to their doctor's office via their phone. Among many other benefits, this should help to significantly reduce health care costs.

"We are already making progress on many of the steps toward the next generation of the system, and it won't be long before we can begin to commercialize it," Faghri said.
