Table 1. Size and surface charge of SPIONs with/without plasma corona.
Particles | DLS hydrodynamic (nm) a | Zeta potential (mV) a |
---|---|---|
CSNP | 124.8 (±4.8) | -19.92 (±0.86) |
CSNP@protein corona | 391.7 (±11.7) | -11.24 (±0.39) |
Nanomag-D-spio | 81.8 (±1.2) | -4.87 (±0.69) |
Nanomag-D-spio@protein corona | 111.1 (±8.01) | -9.79 (±0.4) |
DLS values are measured in RPMI 1640 cell culture medium (pH = 7.4) without FCS at 37°C.
aMeasurements were performed on a colloidal suspension of particles, mean values ± SD, n = 3.
