Attachment of particles to different functionalized surfaces: 20× magnification images of a) E. coli MG1655‐based (bacteria with pili) bacteriabots, b) E. coli ECM1‐based (bacteria without pili) bacteriabots, and c) pristine microparticles attached to mannose‐functionalized surfaces; 20× magnification images of d) E. coli MG1655‐based (bacteria with pili) bacteriabots, e) E. coli ECM1‐based (bacteria without pili) bacteriabots, and f) pristine microparticles attached to BSA‐functionalized surfaces (scale bar = 20 µm). g) A comparison between the attachment efficiency of different bacteriabots to BSA‐ and mannose‐functionalized surfaces. Kolmogorov–Smirnov test (nonparametric and unpaired t‐test) was applied to analyze the results and significant differences (****) were expressed when p < 0.05. Error bars indicate standard error of the mean (n = 10).
