Physical characterization of MIONs. (a) Dynamic light scattering (DLS) of (1) JHU MIONs – 55 nm, (2) Si-MIONs – 81 nm and (3) AuSi-MIONs – 145 nm. (b) SQUID magnetometry measurements of magnetization of MIONs as a function of external field strength. Data are normalized by total solid content, without removal of the silica and gold contributions. (c) Transmission electron microscopy (TEM) of (1) JHU MION cores, (2) silica-coated MIONs and (3) gold and silica-coated MIONs.
