Graffiti protection and easy-to-clean surfaces – how does that work and is it safe?
Special coatings are used to generate self-cleaning surfaces or anti-graffiti-protection. The coatings are virtually invisible and protect the base material […]
Is the UV-protection in nanomaterial-containing sunscreens only effective if the nanomaterials enter the skin and how are they excreted later?
No, to effectively act as inorganic UV-blocker (also called mineral UV-blocker) in sunscreen, the materials either in nanoform or lager […]
Can nanomaterials used in sunscreen cross the skin barrier and enter the body?
Typically nanomaterials used in sunscreens like titanium dioxide or zinc oxide (inorganic uv-blockers) as well as the organic nanoscale UV-blockers […]
Why do pesticides contain nanomaterials?
The main motivation to use nanomaterials in pesticide formulations is to increase the solubility of the active ingredient. This has […]
Is it possible to specifically recycle nanomaterials from products?
No, a recovery of nanomaterials from a product is not feasible, because the nanomaterials are often tightly embedded in a […]
What is nanoplastic and what is it applied for?
Nanoplastics are particles that comprise various polymers (e.g. PET – Polyethylene terephthalate, PS – Polystyrene). Depending on the definition used […]
Comparing nanomaterials with microplastics – What is the difference?
The main difference between nano- and microplastics is the respective size range. Microplastics are exclusively composed of polymers such as […]
Nanosilver in the refrigerator – is this poisoning my food and making me sick?
Silver has been used since thousands of years to keep water sterile. Nowadays nanosilver is more and more used for […]
Nano in food packaging – is this already on the market and is it safe?
In food packaging many different materials are used and for nanomaterials many application possibilities exist, thus, there is no general […]
Why does sunscreen contain nanomaterials in the first place?
Two different groups of UV-blockers are used in sunscreen to protect against UV radiation: inorganic (also called mineral) and organic […]
