摘要
(Figure Presented) Catching the flu: Magnetic particle aggregation has been used to provide a highly sensitive, NMR-based sensor for detecting antibodies to an influenza virus. To achieve high sensitivity, a homogeneous magnetic field (H) was employed to enhance antibody-based cross-linking between particles suspended in solution (see scheme; ΔT2: change in the transverse relaxation time). © 2008 Wiley-VCH Verlag GmbH & Co.
