Surface Energy Base Component (${\mathit{\gamma }}_{\mathit{s}}^{-}$) Comparison of Phenyl Acrylic Coatings, Collagens, and Bacteria

All units are mJ/m² ± SEM where number of samples (N) is 36 (3a), 24 (3b), 18 (3c), 18 (3d), 24 (3e), 36 (3f), 18 (3g), 18 (collagen, insoluble), 36 (collagen, soluble), 21 (S. aureus), and 18 (P. aeruginosa). See Transparent Methods.

^aCalculations based on contact angles from bromonaphthalene, formamide, and water for insoluble collagen (100 μg/mL).

^bCalculations based on contact angles from bromonaphthalene, formamide, and water for soluble collagen (100 μg/mL) in phosphate buffer solution (1x, pH = 7.4).

^cCalculations based on contact angles from bromonaphthalene, dimethylsulfoxide, and water.

^dObtaining a smooth coating without smearing or orange peeling was difficult and may have contributed to an anomalous/inaccurate surface energy profile; however, for completeness, the surface energy profile for 3b was included in the dataset.
