Fig 5. Measurement of water contact angles before degradation (Day 0) and after degraded in PBS for 1, 2.5, or 7 days.

Fig 5

On Day 0, the No Treatment and Plasma groups are statistically significant from all other groups, including each other (*, p < 0.05). On every other day, only the No Treatment group is statistically significant from all other groups (*, p < 0.05). No group showed a significant change with respect to time, except for the Plasma treated group between Day 0 and Day 1 and the GRGDS group between Day 0 and Day 7 (▲, p < 0.05).
