New Lab-On-A-Chip For Instant Blood-Tests

January 12, 2011 Leave a comment Go to comments

“While most blood tests require shipping a vial of blood to a laboratory for analysis and waiting several days for the results, a new device invented by a team of engineers and students at the University of Rhode Island uses just a pinprick of blood in a portable device that provides results in less than 30 minutes.

“This development is a big step in point-of-care diagnostics, where testing can be performed in a clinic, in a doctor’s office, or right at home,” said Mohammad Faghri, URI professor of mechanical engineering and the lead researcher on the project. “No longer will patients have to wait anxiously for several days for their test results. They can have their blood tested when they walk into the doctor’s office and the results will be ready before they leave.”

With the new lab-on-a-chip technology, a drop of blood is placed on a plastic polymer cartridge smaller than a credit card and inserted into a shoebox-sized biosensor containing a miniature spectrometer and piezoelectric micro-pump. The blood travels through the cartridge in tiny channels 500 microns wide to a detection site where it reacts with preloaded reagents enabling the sensor to detect certain biomarkers of disease.”
