Cell viability effect of media after soaking PCL-Cu and PCL-Cu-COOH for 1 and 2 h. Cells were seeded in 96 well plates after 24 h media was replaced by medium soaked PCl-Cu and PCL-Cu-COOH. For PCL-Cu 1 h: conc 1 = 2.3 µg/mL; conc 2 = 1.15 µg/mL, conc 3 = 0.57 µg/mL and conc 4 = 0.29 µg/mL. PCL-Cu 2 h: conc 1 = 3.5 µg/mL; conc 2 = 1.75 µg/mL, conc 3 = 0.87 µg/mL and conc 4 = 0.44 µg/mL. For PCL-Cu-COOH 1 h: conc 1 = 1.8 µg/mL; conc 2 = 0.9 µg/mL, conc 3 = 0.45 µg/mL and conc 4 = 0.23 µg/mL. PCL-Cu-COOH 2 h: conc 1 = 2.9 µg/mL; conc 2 = 1.45 µg/mL, conc 3 = 0.73 µg/mL and conc 4 = 0.36 µg/mL.
