Cell experiments in nanostructured hydrogel channels: a) Scheme presenting the biofunctionalization of the Au-NPs. b) Static fluorescence image of KG1a cells inside a nanostructured channel (125 μm). c) Overlay (maximum intensity) of 150 images showing the movement of different cells (sticking, freely floating or interacting) in a channel (125 μm) with 34 nm spacing. d) Representative trajectories of KG1a cells in channels (125 μm) equipped with functionalized gold nanoparticles of * 34 nm spacing, ** 108 nm spacing or *** no Au-NPs. Wall shear stress = 1 dyn/cm2.
