Latest Samuel K. Sia Stories
Engineers have created a $34 smartphone accessory that can test for HIV and other diseases in just 15 minutes.
Samuel K. Sia, associate professor of biomedical engineering at Columbia Engineering, has taken his innovative lab-on-a-chip and developed a way to not only check a patient's HIV status anywhere in the world with just a finger prick, but also synchronize the results automatically and instantaneously with central health-care records—10 times faster, the researchers say, than the benchtop ELISA, a broadly used diagnostic technique.
The innovative development of the lab-on-a-chip is allowing scientists to perform complex laboratory assays with such simplicity that these tests can be carried out in the most remote regions of the world.
An inexpensive and portable blood test could provide a breakthrough in diagnosing infections and has been proven as accurate as expensive hospital-based testing in the detection of HIV, syphilis and other diseases.
