DLS Measurements of Nanoparticle Size and Zeta Potential to Compare the Dispersion Characteristics of Particles in Simplified and in vitro Biological Representative Media

Nano Powder	Dispersion Media	DLS Mean ± S.E. (nm)	Zeta Potential ± S.E. (mV)
gAgNPs ≥100 nm	Milli-Q-H2O	122± 2.0	−11.4± 2.6
	DMEM/un-supplemented media	160± 3	−9.1 ± 2.4

Notes: Data represent the mean ± standard error of the mean (S.E) of three-independent experiments, carried out at 24°C, with each experimental mean generated from triplicate measurement of each sample (n = 3).
