Graphene Nanoplatelets (GNP)
Graphene Nanoplatelets (GNP) consist of small stacks of graphene that can replace carbon fiber, carbon nanotubes, nano-clays, or other compounds in many composite applications. When they are added at 2-5wt% to plastics or resins they make these materials electrically or thermally conductive and less permeable to gasses, while simultaneously improving mechanical properties like strength, stiffness, or surface toughness. The GNPs that all have the same image are the plasma exfoliated products.
GNPs consist of several sheets of graphene with an overall thickness of approximately 3-10 nanometers depending on the specific product. Graphene Nanoplatelets are friable to 4 layers thick.

Cellulose
Nanocellulose refers to cellulose in the nanometre scale and is a material derived from natural materials including plants and bacteria. But it can also be produced from sugars through biotechnological processes using bacteria that give the product its’ final name – bacterial nanocellulose. Production processes in the 1980’s were energy-intensive, but substantial progress has been made in recent times to reduce these energy costs associated with nanocellulose production. Today, various commercial applications for nanocellulose exist. For example, treatment of wood and hardboard is done with nanocellulose and it functions as barrier material in food packaging materials. Hygiene products for medical applications contain nanocellulose due to its capacity to store large amounts of water. In dietary supplements nanocellulose is used as a thickening agent and stabiliser.
How can I come into contact with this material?
Nanocellulose can directly come into contact with the human skin (dermal uptake) because of its use in medical implants or in wound care applications. Nanocellulose or cellulose nanoparticles can also be swallowed (oral uptake) when used in dietary supplements.
Is there any risk from this material to humans and the environment?
Nanocellulose is considered to be non-toxic and causes no rejection reactions in the body. There are no existing safety concerns for nanocellulose as dietary supplements, although it has been found that the intestinal wall is permeable to this material. Research has shown that only very high concentrations of nanocellulose are able to affect cell growth.
Conclusion
Humans regularly get in contact with nanocellulose through various sources like hygiene products. But there are no known health and safety concerns resulting from the use of nanocellulose containing products.
By the way…
- Ordinary cellulose is permitted without a limit on food (E460).
Cerium Dioxide
Cerium dioxide (CeO2) has a variety of applications. For example ceria nanoparticles are used in catalytic converters in the automotive industry to convert harmful carbon monoxide to less harmful carbon dioxide. The semi-conductor industry uses cerium dioxide nanoparticles as fine abrasive and polishing agent in the manufacturing of computer chips. Non-nanoscaled cerium dioxide can improve the light production/output in mantles of gas lanterns as the gas flame produces almost no light itself, whereas burning cerium oxide generates a yellowish-white colour.
How can I come into contact with this material?
Ceria nanoparticles may be present in the ambient air as the material is used as a catalyst/additive in some automotive fuels. However, there is no information available on this material with regards to the environment or on other sources that may release cerium dioxide nanoparticles. The chance of human exposure to ceria nanoparticles derived from applications such as gas lanterns or computer chips is very low since mantles in gas lanterns are rarely produced nowadays and they do not make use of cerium dioxide nanoparticles at all. Equally the production of computer chips during which ceria is uses as polishing agent takes place in highly isolated rooms.
Is there any risk from this material to humans and the environment?
Little information exists on the effects of cerium dioxide nanoparticles on humans or the environment. Literature sources show that there could be positive and negative effects. There is no danger associated with small amounts of cerium dioxide. Currently it is also assumed that very little nano-scaled cerium dioxide exists in the environment.
Conclusion
Future studies need to be performed to conclusively determine the effects of cerium dioxide nanoparticles on humans and on the environment. Currently various international research projects are focused on investigating the effects, including the long-term effects, of cerium dioxide nanoparticles.
By the way…
- Cerium, as cerium oxide, is a rare metal and was named after the dwarf planet Ceres that is located in the asteroid belt between Mars and Jupiter. It is not clear if either cerium or cerium dioxide is present on Ceres. The NASA probe Dawn, who arrived at Ceres in February 2015, could not clarify this: cerium was simply not on the agenda for this research program.
Iron and iron oxides
Iron is the highest occurring metal found in the earth crust. Iron ore is the starting material to produce iron oxides which are used in various applications ranging from the production of steel to data storage devices. Currently applications of iron oxide nanoparticles in medical uses, such as contrast agents or tumour therapeutic agents, are being tested.
How can I come into contact with this material?
There is little chance for the user to come into contact with iron and iron oxide nanoparticles used in electronic devices and in data storage media. In the medical field, however, iron oxide nanoparticles are injected directly into the human body. Therefore it is extremely important to ensure that the used concentrations of the iron oxide preparations are non-toxic.
Is there any risk from this material to humans and the environment?
The administered amounts of iron and iron oxide used in medical applications are very small compared to the natural iron supplies within the body and are considered non-toxic. Naturally occurring iron oxides are ubiquitously found in the environment making it difficult to distinguish between the naturally occurring forms and synthetically produced iron oxide nanoparticles. Environmental engineers are using this material for environmental remediation purposes such as the removal of toxic compounds from ground water where the nanoparticles usually remain after the chemicals have been eliminated. In general iron and iron oxide nanoparticles are considered to be non-toxic to the environment and its inhabitants, only exceptionally high concentrations can be problematic. Nevertheless it is essential to differentiate between the effects of metallic iron and the respective iron oxides as the former cannot be taken up by organisms. Iron oxides however are important trace elements which can cause adverse effects in both humans and wildlife when administered in excessive amounts.
Conclusion
In the day-to-day life the human body is only exposed to very small amounts of iron nanoparticles or iron oxide nanoparticles which are considered generally to be non-toxic. Iron and iron oxide are naturally occurring materials in the environment.
By the way…
- Iron oxide is also used as colour pigment to create the typical rust red colour. It is a long-lasting dye that can been found in many ancient paintings.
- Pigeons and bacteria are known to store iron oxide particles within their bodies to enable orientation with regard to the earth’s magnetic field.
Fullerenes
Fullerenes, also called bucky balls, are a very new modification of pure carbon and their form resembles soccer balls. They consist out of 20 hexagons and 12 pentagons with a carbon atom in each of edges of this lattice structure. There are only very few applications of this new material class.
How can I come into contact with this material?
Up to now fullerenes are only used in two prominent types of applications which however are not found in Europe. Fullerene nanoparticles are introduced into plastics and other composite materials to improve the products’ properties and a Japanese company is currently producing fullerene-containing cosmetics. Fullerene nanoparticles have excellent radical scavenging properties which is why they were added to an expensive line of anti-ageing cosmetic products resulting in a direct contact of the nanomaterial with the skin. Further possible applications have not yet been put into practice.
Is there any risk from this material to humans and the environment?
So far, there are only a few reliable studies on their health effects on humans or animals. Several studies investigated the distribution of fullerenes in the body and clearly demonstrated that these very small particles (only 0.7 nm in diameter) can penetrate tissue barriers. This fact is only true for individually occurring fullerene nanoparticles which normally exist in an agglomerated state thus reducing the penetration potential of tissue barriers significantly.
Conclusion
Fullerenes are not produced in high quantities and the actual amounts used in everyday products are so small that any possible negative effects can be ruled out. The situation might change however if new products are put on the market that contain considerable amounts of fullerene nanoparticles.
By the way…
- Actually fullerenes are too small to fulfil the definition requirements of nanomaterials (size between 1-100 nm) which is why ISO and OECD created an exception for this class of materials within the definition.
Graphene
Graphene is a one-atom thick layer of carbon and is considered to be a new wonder molecule. Its production became possible only very recently and graphene is now available for various applications. The term graphene is often applied to many members of the family of graphene-based materials the two most important members being graphene and graphene oxide (GO). Graphene is transparent, flexible and very stable on a molecular level. Various future uses of graphene and graphene oxide are expected, from applications in the fields of electronics, photonics, composite materials, energy generation and storage, sensors, metrology to uses in biomedicine.
How can I come in contact with this material?
Currently, graphene is still an experimental material, which was first discovered in 2004. Therefore, there are only few products or applications on the market (e.g. a tennis racket). The most likely path currently for someone to get into contact is via inhalation (breathing in) of graphene nanoparticles or graphene oxide nanoparticles in a laboratory environment.
Is there any risk from this material to humans and the environment?
So far it is too early to conclude on positive or negative biological effects on humans, but first experiments with animals showed that lung damage can occur after inhalation of graphene nanoparticles. Concern has been raised by lung specialists about the safety of graphene and graphene oxide. They strongly recommend that appropriate inhalation (lung uptake) experiments of graphene must be undertaken in order to better understand the respiratory safety profile of this group of materials.
