a Time-lapse microscopy images illustrating the magnetically boosted 1D microswarm and their robust interaction with the PP microfiber network (see also Supplementary Movie 5). The white arrows in the last image and inset SEM image highlight the adhered 1D microrobots on the microfiber network after 30 min actuation (Scale bar in the inset is 5 μm). b–g Hyperspectral dark-field microscopy (HDFM) analysis for the quantification of the adhered 1D microrobots on the PP microfiber network. Schematic illustrations (b, d) and enhanced dark-field microscopy images (c, e) of the magnetically boosted 1D microswarm (b, c) or static 1D microrobot (d, e)-treated microfiber samples. Spectral profiles collected from several pixels of 1D microrobots and PP microfiber network (f), and the comparison of pixel count ratio factors between the 1D microswarm and static 1D microrobot-treated PP membrane groups (g). Error bars in (g) denote standard deviation from triplicate measurements.
