Abstract
A silver nanoparticle is one of the representative engineered nanomaterials with excellent optical, electrical, antibacterial properties. Silver nanoparticles are being increasingly used for medical products, water filters, and cosmetics, etc. However, silver nanoparticles are known to cause adverse effects on the ecosystem and human health. To utilize silver nanoparticles with minimized negative effects, it is important to understand the behavior of silver nanoparticles released to the environment. In this study, we compared toxicity behaviors of citrate-stabilized silver nanoparticles with polyethylene glycol coated silver nanoparticles in two different ionic environments, which are aquatic environments for developing zebrafish embryo. Depending on the composition of the ionic environment, citrate-stabilized silver nanoparticles and polyethylene glycol coated silver nanoparticles exhibited different behaviors in dissolution, aggregation, or precipitation, which governed the toxicity of silver nanoparticles on zebrafish embryos.
Highlights
Silver nanoparticles (AgNPs) are widely used nanomaterials for industrial and biomedical fields due to their unique physicochemical properties such as excellent conductivity, optical functions, and antibacterial capability [1,2,3,4]
We demonstrated that the toxicity of AgNPs is closely correlated to the dissolution behavior of AgNPs
Recent studies suggested that the Ag+ ions released from AgNPs played critical role to the acute toxicity of zebrafish embryo [11]
Summary
Silver nanoparticles (AgNPs) are widely used nanomaterials for industrial and biomedical fields due to their unique physicochemical properties such as excellent conductivity, optical functions, and antibacterial capability [1,2,3,4]. Because AgNPs are sensitive to the surrounding environment, environmental transformations of AgNPs, such as aggregation, oxidation, or dissolution, frequently occur [7,8]. These transformations are attributed to the reduced thermodynamic stability of AgNPs by substances that constitute the aquatic environment, such as the amount of sulfides, chlorides, or organic matters, ionicNsatnroemnatgertiahls,2a0n18d, 8p, xHFO[R7,P9E]E.RTRhEuVIsE,Wunderstanding behaviors of AgNPs in an aquatic envir2oonfm11ent is important for evaluating the toxicity of AgNPs [10].
