When bodily fluids such as blood are tested for infectious diseases and unhealthy protein levels, they’re typically mixed with antibodies or other biological reactants to produce a positive or negative reaction. Researchers from Arizona State University (ASU) have now come up with an alternative testing system that they claim is just as accurate, but much simpler, quicker and cheaper. It utilizes LED lights and simple microelectronic amplifiers, and actually uses the sample itself as a diagnostic tool. Because it integrates the sample into the process, inventors Antonia Garcia and John Schneider call their device the Integrascope.
