Predicting Cytotoxicity of Metal Oxide Nanoparticles using Isalos Analytics Platform

Abstract A literature curated dataset containing 24 distinct metal oxide (MexOy) nanoparticles (NPs), including 15 physicochemical, structural and assay-related descriptors, was enriched with 62 atomistic computational descriptors and exploited to produce a robust and validated in silico model for prediction of NP cytotoxicity. The model can be used to predict the cytotoxicity (cell viability) of…

Risk Governance of Emerging Technologies Demonstrated in Terms of its Applicability to Nanomaterials

Abstract Nanotechnologies have reached maturity and market penetration that require nano‐specific changes in legislation and harmonization among legislation domains, such as the amendments to REACH for nanomaterials (NMs) which came into force in 2020. Thus, an assessment of the components and regulatory boundaries of NMs risk governance is timely, alongside related methods and tools, as…

Transcriptomics in Toxicogenomics, Part I: Experimental Design, Technologies, Publicly Available Data, and Regulatory Aspects

Abstract The starting point of successful hazard assessment is the generation of unbiased and trustworthy data. Conventional toxicity testing deals with extensive observations of phenotypic endpoints in vivo and complementing in vitro models. The increasing development of novel materials and chemical compounds dictates the need for a better understanding of the molecular changes occurring in…

Transcriptomics in Toxicogenomics, Part III: Data Modelling for Risk Assessment

Abstract Transcriptomics data are relevant to address a number of challenges in Toxicogenomics (TGx). After careful planning of exposure conditions and data preprocessing, the TGx data can be used in predictive toxicology, where more advanced modelling techniques are applied. The large volume of molecular profiles produced by omics-based technologies allows the development and application of…

Exposure medium and particle ageing moderate the toxicological effects of nanomaterials to Daphnia magna over multiple generations: a case for standard test review?

Abstract Pristine engineered nanomaterials (NMs) entering the aquatic environment become ‘aged’ during their lifetime via chemical, physical and/or biological process. Therefore, traditional ecotoxicology tests which were designed for soluble chemicals prior to the emergence of NMs, use pristine NMs and salt-only media which are not representative of realistic NM exposure scenarios. Exposure medium and NM ageing moderation…

JRC Workshop on Safe and Sustainable Smart Nanomaterials

The European Commission’s Joint Research Centre (JRC) and the Directorate-General for Research and Innovation (RTD) will jointly organise a Workshop on Safe and Sustainable Smart Nanomaterials in Ispra (Italy) on 24-25 March 2020. The workshop is focused on smart (responsive, multi-functional) nanomaterials, as such or embedded in products, which are developed for application in industrial sectors such…
