thumb|The biomimetic device BOA (Bionic Oil Adsorber) separates automatically on a purely physical basis oil films from water surfaces. It was developed from the research on Salvina Effect and Lotus Effect in 2018 at the University of Bonn. The oil film (red) is adsorbed onto a biomimetic textile (green) and collected into a floating bowl (grey) for subsequent removal. More information in Barthlott et al. in Phil Trans. Roy. Soc.
