Characterization of SiNPs with (+) and without (−) FITC in the core

Data are from n = 5 independent measurements (at 25 °C, in DMEM (+10% FCS) at 37 °C) performed within the first hour after transfer into the corresponding medium. TRM, transmission electron microscopy; DLS, differential light scattering. Ø = diameter; ζ = zeta potential.

Nanoparticle type	Ethanol			Water		DMEM (+ 10% FCS)

SiNPs (+FITC)	75 ± 2	107 ± 1	+51 ± 1	119 ± 2	+25 ± 1	245 ± 4
SiNPs (−FITC)	52 ± 2	105 ± 3	+37 ± 7	118 ± 6	+33 ± 2	150 ± 15
