Nanoparticle Contaminations on the Skin - Can They be Removed? — •Jonas Schubert1,2 and Max Schnepf1,21Functional Colloidal Materials, Leibniz Institute of Polymer Research Dresden, 01069 Dresden, Germany — 2Physical Chemistry of Polymer Materials, Technische Universität Dresden, D-01062 Dresden, Germany

Nanoparticles (NPs) are used now for centuries and more and more they find their way into applications and products on the market. As the usage of nanoparticles is increasing, also accidental release of NPs is now an important issue for a safe work environment. We found that after a skin contact with quantum dot particles, these NPs are barely to remove by applying soap or other typical decontamination agents. From literature we know that some of the NPs can penetrate the skin and are then potentially be harmful for human health.[1] In this contribution, we present a gel that allows a complete removal of NPs from the skin. This marks a first step towards safe handling of nanomaterials, especially since this point is not yet covered by up-to-date occupational safety guidelines. The presented gel displays therefore an important step for the sustainable and safe use of nanomaterials.
