Silver nanoparticles (AgNPs) are currently widely used and of special interest due to their anti-microbial properties. They have been used extensively in commercial applications and might be the most worrying of the manufactured nanoparticles because of their inherent toxicity. In this work, stable citrate and PEG stabilized AgNPs of three different core size (7, 10 and 20nm) were synthesized, the stability of citrate capped NPs was assessed in ecotoxicology media (used for OECD for Daphnia magna toxicity testing) and the stability of 20nm NPs in environmentally relevant conditions (like presence of humic substances, sunlight, different types of synthetic water, amongst other). The particles were fully characterized before and during the stability tests with a multimethod approach. The methods used were DLS, UV-vis, TEM, AFM, FI-FFF, HR-STEM, EELS, EDX. Not all methods were used for all the samples.
