We present the development of a novel integrated device for airborne nanoparticle filtering with bioinspired nanoscale
functionality. The underlying idea is to investigate the principle of adherent surfaces, e.g. pollen, as a biological model
and transfer this functionality into a technology using functionalized microstructured surfaces offering an efficient
filtering method for nanoscale airborne particles. We investigated the different pollen species for their structural and
biochemical surface properties to achieve bioinspired surface functionality on silicon surfaces. Depending on surface
morphology, the adhesive properties of the surfaces towards aerosol particles could be directly influenced.
