Electron microscopical image of the Sicastar nanoparticles in dry state. The fact that the size of the nanoparticles in the dry state (D _TEM) was nearly the same as in solution indicates that the effect of particle shrinking during the preparation of the samples for TEM is minimal. Sicastar 30: R = 11.7 ± 1.7 nm (±14.3 %), Sicastar 70: R = 32.3 ± 4.1 nm (±12.6 %), Sicastar 300: R = 163.7 ± 11.2 nm (±6.9 %). Scale bar 100 nm
