Interaction of Ulva zoospores with polyethylene glycol coating (PEG), acid washed glass (AWG) and tridecafluoroctyl-triethoxysilane (FOTS) coated surfaces. a Velocity deceleration of exploring spores in close proximity of the surface (0–30 μm) as compared to the speed in bulk water. b Number of spores settled on the surface in a standard assay after 45 min. Analysis of motility patterns: c schematic sketch of the observed motion patterns. d Occurrence of motion patterns ≈40 s recordings (≈60 traces) immediately after injection in the vicinity of three different surfaces PEG, AWG, and FOTS, respectively (adapted from Ref.
