要旨

50 nm Magnetic nanocluster (MNC) was deliberately selected as an efficient probe for the magnetic relaxation switching (MRSw) assay. After surface modification of MNCs with poly(acrylic acid) to give PAA-MNCs, and employing streptavidin-biotin interactions for the MRSw assay model, a few tenths pM concentration of strepavidin could be determined.
