Degradation of pSi discoidal particles in fetal bovine serum. A) SEM images of 1000 nm × 400 nm pSi particles during the degradation process in fetal bovine serum at 37 °C. Time-points: 0, 2 and 8 h; scale bars are 500 nm. B) Degradation kinetics of pSi discoidal particles (600 nm × 400 nm and 1000 nm × 400 nm) as evaluated by ICP-AES. The degradation kinetic profile is expressed as a percentage of the total amount of pSi dissolved in medium.
