From: Oral absorption of PEG-coated versus uncoated gold nanospheres: does agglomeration matter?
Particle characterization: TEM and dynamic light scattering. Transmission electron micrograph of PEG-coated (A) and uncoated (B) gold nanospheres. One-hundred particles were measured for each particle type to determine the average primary particle size to be 14 ± 2 nm. Dynamic light scattering particle size distributions of the as dosed PEG-coated and uncoated particles (C) measured the hydrodynamic diameter of the particles to be 45 ± 2 nm and 23 ± 6 nm, respectively.
