Enhancement of Polymer Cytocompatibility by Nanostructuring of Polymer Surface
Figure 5
Zeta potential values of pristine PLLA (a) and PMP (b) and aged samples modified by Ar plasma (power 3 and 8 W) with exposure times 15, 120, and 240 s. The value of zeta potential was determined using streaming current and streaming potential approaches and two equations (Helmholtz-Smoluchowski (HS) and Fairbrother-Mastins (FM)) [9].
