The graphic highlights the key features of Nano2RED, an innovative diagnostic method invented by professor Wang and his colleagues. The top section illustrates the rapid timeline of steps for production of the test, which can all be carried out in roughly 20 days. The middle section of the graphic shows the basic steps involved. First, a large library of synthetic antibodies or nanobodies is produced and screened against a known antigen (left), next, nanobodies are attached to gold nanoparticles (middle) and finally, disease antigens are detected in a sample when gold nanoparticle-bound nanobodies fuse with them, producing a positive test result, (right).
