This study presents the development of a nanosensor using graphene nanosheets to detect hepatitis E antigen within a minute. The graphene layer not only increases the loading of antibodies specific to the hepatitis E virus but also enhances sensitivity and selectivity. This sensor is sensitive to 10 fM of hepatitis E antigen. This nanosensor holds significant potential for the rapid and early detection and monitoring of hepatitis E, thereby contributing to enhanced public health outcomes and the safety of pork products.Pages 637-6404 page(s)application/pdfenIn Copyrighthepatitis EantibodynanosensorgrapheneConference proceedinghttps://doi.org/10.1109/NANO63165.2025.11113826MS ID#:142Meng, Xiang-Jin [0000-0002-2739-1334]Knowlton, Katharine [0000-0002-7181-4410]Ali, Azahar [0000-0001-5752-8808]1944-9380
