Thrombocyte activation studies. a–c Fluorescence images of activated thrombocytes on top of the 3D structures inside the microfluidic channels. The grids in a–c carry a low, medium and high density of nanoanchors with integrated intensities of \({5.17} \times {{10}}^{{7}}\) counts, \({4.34} \times {{10}}^{{7}}\) counts and \({2.54} \times {{10}}^{{7}}\) counts, respectively. d Fluorescence signal of anti-CD62p-Alexa®647, integrated in the proximity to each structure (picture section of 26.4 × 26.4 µm) for grids 1 to 5 in downstream direction. Each data point is averaged over four experiments. e Average fluorescence from the first four grids for the three experiments with low, medium and high density of nanoanchors
