Cytocompatibility of Plasma and Thermally Treated Biopolymers
Figure 4
Zeta potential results for PLLA pristine (PLLA), plasma treated (PLLA/5 W/240 s), and annealed ones at 60°C (PLLA/60°C and PLLA/5 W/240 s/60°C). HS means the streaming current method and Helmholtz-Smoluchowski equation; FM means the streaming potential method and Fairbrother-Mastins equation.
