Sub-micron vibrations modulate bacterial adhesion to a chemically active surface. (A) Quantitative analysis of area covered by E. coli, S. aureus and S. epidermidis bacterial colonies shows significant (p < 0.05) reduction in adhesion to PLLA treated material surfaces when subjected to vibrations; (B) Quantitative measurements were normalized to non-vibrated samples. Error bars represent ±S.E.M.
