On August 2, 2023, the European Union (EU) Observatory for Nanomaterials (EUON) announced that it published a study that systematically reviews and assesses alternative methods for the testing of the safety of nanomaterials without the use of animals. According to EUON, the main aim of the study was to collect and provide accurate and transparent information on new approach methodologies (NAM) available for the human safety assessment of nanomaterials and to create a comprehensive...

On June 26, 2023, the European Commission’s (EC) Scientific Committee on Consumer Safety (SCCS) published the second revision of its Guidance on the Safety Assessment of Nanomaterials in Cosmetics. The Guidance covers the main elements of safety assessment, i.e., general considerations (Section 2), material characterization (Section 3), exposure assessment (Section 4), hazard identification and dose-response characterization (Section 5), and risk assessment (Section 6). SCCS states...

On July 31, 2023, the U.S. Environmental Protection Agency (EPA) announced that it provided more than $1.3 million in funding to a team of researchers from the University of Wisconsin-Madison to develop nanosensor technology that can detect, monitor, and degrade commonly used pesticides found in water that can harm human health. According to EPA, using funding from the grant, researchers will develop an integrated, portable, sensor-controlled water treatment technology that itself...

On September 20, 2023, the Organization for Economic Cooperation and Development (OECD) will hold a webinar on Test Guideline No. 126: Determination of the Hydrophobicity Index of Nanomaterials Through an Affinity Measurement. The webinar will present the method to determine the hydrophobicity index (Hy) of nanomaterials, through an affinity measurement, described in the OECD Test Guideline (TG) No. 126. According to OECD, webinar attendees will be able to learn the use and limitation...

The Organization for Economic Cooperation and Development (OECD) announced on July 4, 2023, that it published a number of new, updated, and corrected Test Guidelines (TG), including the following for nanomaterials: TG No. 126: Determination of the Hydrophobicity Index of Nanomaterials through an Affinity Measurement: This new TG describes a method to determine the hydrophobicity index (Hy) of nanomaterials, through an affinity measurement. OECD states that hydrophobicity is defined as...

Switzerland’s Federal Office of Public Health (FOPH) has updated its precautionary matrix for synthetic nanomaterials, which is a method for assessing the nano-specific health and environmental risks of nanoproducts. According to FOPH, the precautionary matrix enables the structured assessment of the “nano-specific need for precautions” when handling synthetic nanomaterials. The precautionary matrix is designed “to help industry and trade comply with their due diligence and their...

The European Commission’s (EC) Scientific Committee on Health, Environmental and Emerging Risks (SCHEER) announced the release of its final opinion on the safety of titanium dioxide in toys on June 27, 2023. Following the mandate from the EC, the scientific opinion evaluates whether the uses of pigmentary titanium dioxide in toys and toy materials can be considered to be safe in light of the exposure identified and in light of the classification of titanium dioxide as carcinogenic category 2...

According to NNI, the roundtable is a critical part of the Nano4EARTH National Nanotechnology Challenge, which aims to leverage recent investments in understanding and controlling matter at the nanoscale to develop technologies and industries that address climate change. Nano4EARTH focuses on facilitating opportunities for members of the nanotechnology community to convene, collaborate, and share resources. Nano4EARTH also strives to provide mechanisms that support technology development and...

POSTED IN INTERNATIONAL, LEGAL/REGULATORY ISSUES, OECD The Organization for Cooperation and Development (OECD) has published the latest edition of the Developments in Delegations on the Safety of Manufactured Nanomaterials and Advanced Materials — Tour de Table. The Tour de Table compiles information provided by delegations on the occasion of the 22nd meeting of the OECD Working Party on Manufactured Nanomaterials (WPMN) in June 2022. Below are highlights on...

The European Union (EU) Observatory for Nanomaterials (EUON) has posted two Nanopinions: “Seeing is believing,” posted on April 11, 2023, by Dr. Chandima Bulumulla, Postdoctoral Fellow at the Janelia Research Campus of the Howard Hughes Medical Institute, and Dr. Abraham G. Beyene, Group Leader at the Janelia Research Campus of the Howard Hughes Medical Institute. The column explains how single-walled carbon nanotubes (SWCNT) can help measure biochemical processes happening inside the brain....
