• sticking of an artificially nonwoven of nanofibers. According to the theoretical prediction, a technical analogon of the nanoripples was produced by ultrashort pulse laser processing on different technically relevant metal surfaces in the form of so-called laser-induced periodic surface structures (LIPSS

• randomly rough surfaces. The latter revealed that the adhesion of electrospun nanofiber nonwoven is significantly lowered on the nanostructured surfaces compared with the polished surfaces. Keywords: biomimetics; electrospinning; laser-induced periodic surface structures (LIPSS); nanofibers

• surface structure, in contrast to earlier published works where solids with plane surfaces were assumed [24][25][26][27][28]. This is an important difference, which has to be considered when modelling the interaction of nanofibers with, in this case, a sinusoidal surface. Laser-induced periodic surface

• -induced periodic surface structures (LIPSS [19]) and round melting features form on the glass surface (Figure 5b). The LIPSS with periods in the sub-micrometer range are generated via intra-pulse scattering and interference of the fs-laser radiation at the roughened glass surface, leading to the spatially

• surface topography needs to be mimicked, but often also a specific function of the structure. An alternative approach to laser direct writing of complex structures is the generation of laser-induced periodic surface structures (LIPSS), which is based on directed self-organization of the material and
