- Diqing Su, a third-year materials science Ph.D. candidate in Professor Jian-Ping Wang’s group, recently won "Best Poster Award" for her poster titled “Giant Magnetoresistance Based Handheld Platform for Rapid Detection of Influenza A Virus” at the 62nd Annual Conference on Magnetism and Magnetic Materials (MMM) in Pittsburgh. Su’s poster was one of over 100 total posters being presented in the competition. The 2017 MMM Conference attracted researchers from all over the world for a discussion of a variety of topics on magnetism and magnetic materials
Diqing and her colleagues from the research groups of Professor Jian-Ping Wang and Professor Andres Perez demonstrated the outstanding performance of their GMR-based handheld system in the sensitive detection of Influenza A virus. By using a sandwich structure of capture antibody-antigen-detection antibody-magnetic nanoparticles on the GMR sensor surface, the detecting system can successfully detect both Influenza A Virus nucleoprotein and the purified H3N2 virus sample with a detection limit better than the Enzyme Linked Immunosorbent Assay (ELISA), which is a commonly used method for the virus detection. Moreover, with the size of a snack container and a user-friendly interface, this handheld system is capable of onsite detection, and the whole detection process can be finished within 10 minutes.
