Inexpensive medical diagnostic tests that take only a few minutes to perform
By mimicking nature's own sensing mechanisms, bioengineers at UC Santa Barbara and University of Rome Tor Vergata have designed inexpensive medical diagnostic tests that take only a few minutes to perform. Their findings may aid efforts to build point-of-care devices for quick medical diagnosis of sexually transmitted diseases (STDs), allergies, autoimmune diseases, and a number of other diseases. The new technology could dramatically impact world health, according to the research team.
The rapid and easy-to-use diagnostic test consists of a nanometer-scale DNA "switch" that can quickly detect antibodies specific to a wide range of diseases. The research is described in an article published this month in the Journal of the American Chemical Society.
