2018 J. R. Soc. Interface. Sessile marine organisms usually use glues to stick to natural and, unfortunately, man-made surfaces. Conventional strategies to protect man-made surfaces against this so called “biofouling” constantly release harmful chemicals into the marine environment. Based on physical principles only, Petersen and co-workers present a new promising and emission-free coating that can prevent permanent adhesion of barnacles. The coating combines a soft silicone-based material with a re-entrant, non-wettable surface topography. Barnacles don’t completely wet the coating, and thus can’t form a reliable adhesive joint with it. For that reason they stick very poorly and can be detached by e.g. natural water flow without any harmful impact on the environment. The results were published in the scientific journal Journal of the royal society interface on 22 August 2018. DOI: 10.1098/rsif.2018.0396 Original Paper

Advanced Materials/ACS Applied Materials & Interfaces. Geckos, spiders and beetles have shown us how to do it: thanks to special adhesive elements on their feet, they can easily run along ceilings or walls. The science of bionics tries to imitate and control such biological functions, for technological applications and the creation of artificial materials. A research team from Kiel University (CAU) has now succeeded in boosting the adhesive effect of a silicone material significantly. To do so they combined two methods: First, they structured the surface on the micro scale based on the example of beetle feet, and thereafter treated it with plasma. In addition, they found out that the adhesiveness of the structured material changes drastically, if it is bent to varying degrees. Among other areas of application, their results could be interesting for the development of tiny robots and gripping devices. They have been published in the latest editions of the scientific journals Advanced Materials and ACS Applied Materials & Interfaces. Original Paper

  2018 New thematic series of Beilstein Journal of Nanotechnology. The thematic series Biological and biomimetic surfaces: adhesion, friction and wetting phenomena edited by Stanislav N. Gorb (Kiel University), Kerstin Koch (Hochschule Rhein-Waal) and Lars Heepe(Kiel University) discusses experimental methods for the characterization of biological surfaces at the micro- and nanoscale. It combines approaches from biology, physics, chemistry, materials science, and engineering and therefore represents an example of modern interdisciplinary science. All papers in the series are Open Access Platinum. Original Issue (Open Access): Web

2017 Science Robotics. An interdisciplinary research team from Biology (E. Kizilkan, S. N. Gorb) and Chemistry (J. Strueben, A. Staubitz) has now succeeded in developing a bioinspired adhesive material that can be controlled remotely by using UV light. This way it is possible to precisely transport objects in a micro-range. The findings could be interesting for applications in the fields of robotics and medical technology. The Kiel-based research team's results were published in the scientific journal Science Robotics on 18 January. Sci. Robot. 2, eaak9454 (2017). DOI: 10.1126/scirobotics.aak9454 Original Paper

2017 J. R. Soc. Interface. . The silk attachment of the pupae and last instar caterpillars of the tea bagworm Eumeta minuscula (Lepidoptera, Psychidae) to the leaves of its host plant Ilex chinensis was experimentally studied. We found that the bagworms spin attachment discs similar to a plaque consisting of numerous overlaid, looped glue-coated silk fibres and the medially attaching suspension thread. The field observations and structural data show that bagworms remove the leaf epidermis prior to silk attachment, in order to ensure a reliable contact to the plant substrate. J. R. Soc.
