“…The T 2 NMRD profile was not determined for technical reasons but, as expected [49], one could observe that r 2 increased with field strength, reaching values around 240 mM −1 .s −1 at 9.4 T for the PEGylated samples. In comparison, McGrath et al [53] reported r 2 values slightly below 230 mM −1 .s −1 at room temperature for Fe@FeOx NPs with comparable core size (11 ± 2 nm) and saturation magnetization (103 A.m 2 .kgFe −1 ), but larger hydrodynamic diameter (180 nm) due to presence of phosphonate-grafted polyelectrolytes at their surface. Figure 8.…”

“…NPs are submicrometer moieties made of organic or inorganic materials and with unique characteristics compared to their bulk counterparts. Besides their intrinsic nanoscale physical phenomena, their often exhibit exceptional optical, electrical, magnetic, and chemical properties, attracting vast attention in many biotechnological areas, such as magnetic resonance imaging, drug delivery systems, hyperthermia and labeling and separation of cells and proteins, among other biological entities . Different kinds of NPs, such as quantum dots, carbon nanotubes, gold NPs, silica NPs, polymeric NPs, and magnetic NPs (MNPs) have been designed and synthesized.…”

“…3c), something that is oen suggestive of carbonaceous coatings. 37 Interestingly, despite nding GlcNAc-coated MNPs bound to Quartz Crystal Microbalance with Dissipation monitoring (QCM-D) chips coated with the GlcNAc-recognising lectin wheat germ agglutinin (WGA), 17 the addition of WGA to 5coated MNPs did not appear to signicantly change the extent of interparticle aggregation (Fig. 3d).…”
