Mechanisms of Silver Nanoparticle Release, Transformation and Toxicity: A Critical Review of Current Knowledge and Recommendations for Future Studies and Applications (2013, background): “However, due to sample preparation, nanoparticles cannot be observed in suspension, so if TEM is the only method used [83] the behaviour of the particles in suspension remains largely unknown.”
Emerging patterns for engineered nanomaterials in the environment: a review of fate and toxicity studies (2014, methodology): “Extended DLVO theory takes into account nonelectrostatic ion-specific forces such as acid–base, steric, magnetic, and hydrodynamic forces (Hyung and Kim 2008; Petosa et al. 2010; Stebounova et al. 2011; Zhu and Cai 2012), all of which can play important roles in the aggregation of ENMs.”
The Toxicity of Silver Nanoparticles (AgNPs) to Three Freshwater Invertebrates With Different Life Strategies: Hydra vulgaris, Daphnia carinata, and Paratya australiensis (2018, background): “Appearance of additional and broader absorbance peaks, rapid absorbance loss, increased particle size and color change are indicative of formation of aggregates (Römer et al., 2011; Stebounova et al., 2011; Tejamaya et al., 2012).”
A review on biosynthesis of silver nanoparticles and their biocidal properties (2018, background): “The formation of AgCl is possible only if the fluid is contaminated with Cl− ions, nevertheless it cannot ionize to Ag+ and Cl− ions since AgCl is almost insoluble in aqueous medium [265].”
Size-dependent cytotoxicity of silver nanoparticles in human lung cells: the role of cellular uptake, agglomeration and Ag release (2014, background): “This is explained by the severe agglomeration that takes place in this solution due to the very high ionic strength [25] since low pH (in low ionic strength solutions) is known to cause higher Ag release [48].”
