Cytocompatibility of Plasma and Thermally Treated Biopolymers

Table 1

The element concentration on the PMP and PLLA samples. The values were determined by XPS method for pristine, plasma treated (5 W or 10 W, 240 s), plasma treated, and aged samples.

Sample	Element concentration (at. %)
	Carbon	Oxygen
PMP
Pristine	99.7	0.3
Plasma 5 W	79.5	20.5
Plasma 5 W/aged	75.5	24.5
Plasma 10 W	80.3	19.7
Plasma 10 W/aged	75.6	24.4
PLLA
Pristine	66.1	33.9
Plasma 5 W	66.3	33.7
Plasma 5 W/aged	61.5	38.5
Plasma 10 W	66.6	33.4
Plasma 10 W/aged	64.8	35.2
