Particle characterization data for citrate and PVP capped AgNP. Hydrodynamic size reported was determined by DLS and reported as Z-average. Core diameter was determined from TEM and Silver concentration by ICP-MS. As reported form The Nanotechnology Characterization Laboratory (NCL, Fredrick, MD) Data are as presented as a mean ± SEM of 6 separate aliquots
