Chemical composition, morphology and size distribution of synthetic citrate-capped AgNPs. (a) Analysis of the elemental composition of the synthetic AgNPs by energy-dispersion X-ray spectrometry (EDX). (b) Shape and actual size of the synthetic AgNPs visualized under a transmission electron microscope (TEM). (c) Differential number-weighted particle-size distribution of the aqueous AgNP suspension measured using dynamic light scattering (DLS).
