As reported in our April 8, 2020, blog item, the National Academies of Sciences, Engineering, and Medicine (National Academies) published a prepublication copy of A Quadrennial Review of the National Nanotechnology Initiative:  Nanoscience, Applications, and Commercialization.  The National Nanotechnology Coordination Office (NNCO) asked the National Academies to form an ad hoc committee to…

On May 26, 2020, the European Union (EU) NanoSafety Cluster announced the publication of the final report of the (nano) TiO2 safety communication Task Force.  The goal of the task force was to provide scientific input to the ongoing classification of titanium dioxide (TiO2).  The Task Force ran from January 2018 to…

The European Union (EU) Observatory for Nanomaterials (EUON) announced on May 20, 2020, that a recent study has analyzed existing research on whether nanomaterials used in consumer products and at workplaces are absorbed through the skin.  The study was commissioned by EUON and carried out by the RPA consortium of Triskelion and the Dutch National…

On April 12, 2020, the World Health Organization (WHO) published Environmental Health Criteria 244:  Principles and methods to assess the risk of immunotoxicity associated with exposure to nanomaterials.  WHO states that the document presents an overview of the current knowledge and evidence on principles and basic mechanisms of immunotoxicity caused by engineered nanomaterials (ENM). …

The International Organization for Standardization (ISO) has published standard ISO/TS 11308:2020, “Nanotechnologies — Characterization of carbon nanotube samples using thermogravimetric analysis.”  The standard provides guidelines for the characterization of carbon nanotube (CNT)-containing samples by thermogravimetric analysis (TGA), performed in either an inert or oxidizing environment.  The standard offers guidance on the purity assessment…

The European Union (EU) Observatory for Nanomaterials (EUON) posted an article on April 6, 2020, announcing the availability of a study that found a lack of data on female fertility.  The study, A critical review of studies on the reproductive and developmental toxicity of nanomaterials, was commissioned by the European Chemicals Agency (ECHA) and…

The National Academies of Sciences, Engineering, and Medicine (National Academies) have published a prepublication copy of A Quadrennial Review of the National Nanotechnology Initiative:  Nanoscience, Applications, and Commercialization.  The National Nanotechnology Coordination Office (NNCO) asked the National Academies to form an ad hoc committee to conduct a quadrennial review of the National Nanotechnology Initiative…

The U.S. Environmental Protection Agency published a proposed rule on April 1, 2020, that would amend the significant new use rules (SNUR) for certain chemical substances that were the subject of a premanufacture notice (PMN) and a significant new use notice (SNUN), including functionalized multi-walled carbon nanotubes (MWCNT) (generic).  85 Fed. Reg. 18173.  This action…

On March 30, 2020, the National Nanotechnology Initiative (NNI) released a “Nano Matters” podcast episode on “Improving Pesticide Use with Nanotechnology.”  In the episode, Cristina Sabliov, Professor of Biological and Agricultural Engineering at Louisiana State University, explains how nanotechnology can improve pesticide delivery.  She discusses her work on a polymeric nanoparticle delivery system…

The International Organization for Standardization (ISO) has published standard ISO/TS 19808:2020, “Nanotechnologies — Carbon nanotube suspensions — Specification of characteristics and measurement methods.”  The standard specifies the characteristics to be measured of suspensions containing multi-walled carbon nanotubes (carbon nanotube suspensions).  The standard includes the essential and additional characteristics of the carbon nanotube suspension,…
