DLS and ζ-Potential analyses of MYTS, MYTS-EDBE, MYTS-PEG. The hydrodynamic diameter was obtained by number size distribution. Data represent mean ± SD of three independent measurements.

	Hydrodynamic Diameter (nm)	Polydispersity Index (PDI) *	ζ-Potential (mV)
MYTS	30.3 ± 0.9	0.152 ± 0.009	−41.2 ± 0.8
MYTS-PEG	35.1 ± 0.8	0.133 ± 0.007	−37.1 ± 3.8
MYTS-EDBE	35.0 ±1.4	0.143 ± 0.010	−35.7 ± 0.3

* Polydispersity Index (PDI) is a useful parameter to determine the size distribution of a colloidal nanoparticle dispersion in a certain medium. Conventionally, PDI values below 0.3 suggest that the quality of size distribution is good, while below 0.15 is excellent.
