Gold nanoparticles, coated with specific antibodies to viruses, bacteria, or virtually any disease-causing agent, now form the basis of a diagnostic system 100,000 times more sensitive than current technologies and capable of delivering a result in about 15 minutes. Molecular bioengineers at Arizona State University have developed the reagents and the detection device they’ve named the NasRED, which stands for Nanoparticle-Supported Rapid Electronic Detection.

For example, when exposed to say antigens from CoVid viruses, the CoVid-antibody coated gold nanoparticles clump together and capably reflect light in the NasRed detector. This one-drop blood test can rapidly and precisely detect COVID-19, influenza, HIV, Ebola, and/or Lyme with unprecedented precision. Each test costs about two dollars, a fraction of the price of current lab methods. The detection device is small and portable permitting its use in rural hospital and clinics.

Work is already underway to shrink the test prep and detection devices even further, raising the possibility of a do-it-yourself home test with better than lab-quality accuracy……someday soon.
