Biochip could detect multiple viruses, cancers, or toxins in minutes

Excerpt:

So the technique could allow doctors to detect viral infections without first having to amplify the genetic material from a patient, [..] making it possible to detect in minutes not just whether a particular virus is present, but how intense the infection is. [..] Current tests can also do this, but they normally take several hours to amplify the genetic material and quantify the results.
