The European Union (EU) Observatory for Nanomaterials (EUON) has posted two Nanopinions: “Graphene Electronic Tattoos,” posted on February 20, 2023, by Dr. Dmitry Kireev. “Graphene Electronic Tattoos (GETs) are a type of skin-wearable electronic device that can be used for personalized healthcare by transmitting the bio-electrical activity of the human body in the measurable electrical signal. […] The GETs are optically transparent, lightweight, and flexible, making them adhere and...

The European Union (EU) Observatory for Nanomaterials (EUON) announced on December 7, 2022, publication of a June 2022 report by the European Chemicals Agency (ECHA) entitled Assessment of the potential impact of graphene, graphene oxide and other 2D materials on health, and the environment. Commissioned by EUON, the report provides a systematic review and critical assessment of the health and environmental effects of graphene, graphene oxide, and other two-dimensional (2D)...

On January 18, 2022, the European Union (EU) Observatory for Nanomaterials (EUON) published a Nanopinion entitled “What does ‘Graphene’ really look like and why is it not ‘carbon nanotubes’” by Dr. Alberto Bianco, Dr. Maurizio Prato, and Dr. Kostas Kostarelos, of the Graphene Flagship, an EU research initiative, about graphene and why it is not the same as carbon nanotubes. The article states that in particular, the authors wish to emphasize “that ‘graphene’ as a single type of...

The European Chemicals Agency (ECHA) has launched a call for tenders to perform a study “Assessment of the potential impact of graphene, graphene oxide and other 2D materials on health, and the environment” as part of the European Union (EU) Observatory for Nanomaterials (EUON). According to the description, the goal of the study is to conduct a systematic literature review of the health and environmental effects of graphene, graphene oxide, and other two-dimensional (2D) materials, based on...

The March 2021 issue of Environmental Factor, a monthly newsletter published by the National Institute of Environmental Health Sciences (NIEHS), includes an item entitled “New graphene nanochannel filters hold promise for contaminant clean-up.”  According to the item, an NIEHS-funded study found a new strategy to design nanomaterials to filter contaminants better from water.  To improve the usefulness of graphene oxide nanosheets for filtering contaminants from liquid, the...

On August 26, 2019, the National Institute of Environmental Health Sciences (NIEHS) announced that the results of an NIEHS-funded study show that graphene could provide alternatives to chemicals in insect repellant and protective clothing.  The study, “Mosquito Bite Prevention through Graphene Barrier Layers,” was published in the Proceedings of the National Academy of Sciences.  According to the abstract, the researchers hypothesized that graphene films may provide...

The International Organization for Standardization (ISO) has published standard ISO/TR 19733:2019, “Nanotechnologies — Matrix of properties and measurement techniques for graphene and related two-dimensional (2D) materials.”  ISO states that since graphene was discovered in 2004, it has become one of the most attractive materials in application research and device industry due to its supreme material properties such as mechanical strength, stiffness and elasticity, high electrical and...

The European Commission (EC) has published a success story, “Controlling light at the nanoscale thanks to graphene.”  The EC notes graphene, “an atomically thin lattice of carbon, has many exceptional properties.”  A European Union (EU)-funded project is focusing on the unique capabilities of graphene plasmons to transport and control light emissions at spatial scales far smaller than their wavelength.  They can be exploited in numerous applications, including for infrared biosensing...

On March 20, 2018, the American National Standards Institute (ANSI) Nanotechnology Standards Panel (ANSI-NSP) will meet at the U.S. Department of Agriculture in Washington, D.C.  The focus of the meeting will be to consider the observations from the February 28, 2017, ANSI-NSP meeting on graphene standards, including the following issues: Terminology; Characterization methods; and Information sharing. Participants will discuss recommendations for future standardization...

The International Organization for Standardization (ISO) has published standard ISO/TS 80004-13:2017, “Nanotechnologies — Vocabulary — Part 13:  Graphene and related two-dimensional (2D) materials.”  According to ISO, over the last decade, interest has arisen in graphene due to its “many exceptional properties.”  More recently, other materials with a similar structure have also shown promising properties, including monolayer and few-layer versions of hexagonal boron nitride,...
