Doctoral candidate Diqing Su’s poster titled “Giant Magnetoresistance-based Handheld Platform for Rapid Detection of Influenza A Virus” has been recognized as the best poster among a hundred others that were presented at MMM 2017, the 62nd Annual Conference on Magnetism and Magnetic Materials.
The poster presents the the performance of a giant magnetoresistance(GMR)-based handheld device in detecting the influenza A virus in a biological sample. Using a sandwich structure of capture antibody-antigen-detection antibody-magnetic nanoparticles on the GMR sensor surface, the system can successfully detect both, the influenza A virus nucleoprotein, and the purified H3N2 virus sample. The detection limit of this system is better than the commonly used Enzyme Linked Immunosorbent Assay (ELISA). The size of a snack container with a user-friendly interface, the system is capable of onsite detection, and the whole detection process can be completed within 10 minutes.
The poster presents the work of Diqing and other researchers working in teams lead by Prof. Jian-Ping Wang (from ECE) and Prof. Andres Perez (from the Department of Veterinary Population Medicine). Diqing is a doctoral candidate working under the guidance of Prof. Jian-Ping Wang
