Thickness and mechanical properties of coated catheters. (A) Thickness of PU only and PU+auranofin (3 and 10 mg/mL auranofin coating concentration) on PTFE. (B) Tensile elastic moduli of PU and PU+auranofin (3 and 10 mg/mL auranofin coating concentration) standalone coatings. (C) Representative digital image displaying elongation of standalone PU+auranofin coating formulated with 3 mg/mL auranofin during tensile testing nearing failure (scale bars = 25 mm). (D) Percent elongation at break of PU and PU+auranofin (3 and 10 mg/mL auranofin coating concentration) standalone coatings. Data are shown as mean ± standard deviation with *p < 0.05 and **p < 0.001 for moduli values between samples analyzed using one-way ANOVA with Tukey's post-hoc analysis (n = 3).
