The NO flux-dependent relative adhesion of A) S. aureus, B) MRSA, C) S. epidermidis, D) E. faecalis, E) E. coli, and F) P. aeruginosa to pre-adsorbed Fg PVC-coated xerogels after 1 h of exposure. A relative adhesion of 1.0 represents the adhesion of the strain to control (i.e., non-NO-releasing) substrates. Data are mean ± standard deviation.
