Abstract

We report the direct modification of SPIOs with a biomolecule, and the sequence-specific assembly of the modified SPIOs was achieved with the aptamer-small molecule interaction. In addition, the transverse relaxation rate of the aqueous solutions containing the modified SPIOs was altered by the dispersion state.
