Silver nanoparticles (AgNPs), one of the most common nanomaterials in use today, have been shown to enter the aquatic environment from use of commercially obtained products. Although acute toxicity has been shown in vitro and in vivo, there is still a great deal of uncertainty surrounding the molecu...
Silver nanoparticles cause toxicity in exposed organisms and are an environmental health concern. The mechanisms of silver nanoparticle toxicity, however, remain unclear. We examined the effects of exposure to silver in nano-, bulk- and ionic forms on zebrafish embryos (Danio rerio) using a Next Gen...
Due to its antimicrobial activity, silver nanoparticles (Ag-NPs) are among the most used NPs worldwide, yet little information is available regarding their effects, particularly in soil dwelling organisms. Enchytraeids (Oligochaeta) are important members of the soil fauna which actively contribute t...
The release of silver nanoparticles (SNPs) in the environment has raised concerns about their effects on living organisms, including plants. In this study, changes in gene expression in Arabidopsis thaliana exposed to SNPs and silver ions (Ag+) were analyzed using Affymetrix expression microarrays. ...
This model explores the temporal dynamics of silver nanoparticles (AgNPs)-induced apoptosis using dynamic simulations in COPASI.
It provides a time-resolved framework for understanding how cellular stress progresses to programmed cell death.
Because of the tremendous use of NPs in the agricultural sector (Vernikov et al., 2009) and their interactions with the plants, the effect of NPs in plants needs to be explored at the molecular level. To investigate the effects of varying sizes of silver NPs on early-stage soybean under flooding str...
Nanoparticles are more and more used in industrial process, food, medicinal or daily goods. At the end of their life, most of them are discharged in the environment where they impact the ecological equilibrium. Bacteria are one of the first targets of the nanoparticles in the environment. To evaluat...

We studied the composition of the protein corona formed on 60 nm silver nanoparticles with citrate coating interacted with the human blood plasma under various pH and temperature conditions. The protein corona was analyzed using LC-MS and label-free quantitation.
The toxicity of silver and zinc oxide nanoparticles is hypothesised to be mediated by dissolved metal ions and cerium dioxide nanoparticles (CeO2 NPs) are hypothesised to induce toxicity specifically by oxidative stress dependant on their surface redox state. To test these hypotheses, RNAseq was app...
