Lab-on-a-chip aims to take suspense out of blood work
If your doctor's ever uttered the words, "I'd like to run more tests," you know the wait for results can be torturous. Engineers and students at the University of Rhode Island (URI) are hoping to stop the torture with a new lab-on-a-chip technology that cuts way back on the wait for important lab results. The system provides results in 30 minutes, using a portable device and just a drop of blood. The blood is placed on a small plastic polymer cartridge, smaller than a credit card, and inserted into a shoebox-sized biosensor. It then travels across the cartridge to a detection site where reagents enable the sensor to detect biomarkers of disease. Basically, your doctor pops a bloody piece of plastic into a box, and out come your results. The first cartridges were developed to assess the risk of heart disease, but researches suggest they could be designed to detect everything from HIV to Alzheimer's. The URI team estimates costs at $3200 for the sensor and $1.50 for the test. No official word on a release date, but we hope they won't make us wait too long -- we can't stand the suspense.
German researchers develop biotech sensor bracelet, disposable blood lab
Biochips -- flexible, disposable plastic circuits that "compute" via chemical reaction -- have been nearing reality for over a decade, but for obvious reasons we don't always pay attention. German research institute Fraunhofer IZM has just convinced us it's high time we did. This week, the organization announced that it's on the verge of creating a lab-on-a-chip that can diagnose deep vein thrombosis from a single drop of blood, as well as a wristband that can measure body temperature, skin moisture and electromagnetic radiation using plastic chips and sensors only micrometers thick. Impressive, yes, but the real news is the production process -- these gadgets can be printed in reels and sheets. The organization imagines the tools will be so cheap they'll be disposable; rather than wait for lab results, worried individuals will just take one out, test and toss to feel confident about their bloodwork, before hopefully going back to their normal lives.
