Table 2

Percentage of reduction of fibrinogen (0.5 mg/mL) adsorption compared to LP surface for different coupling concentrations of star PEG. Results are expressed as mean ± SD, 𝑛=4.

Surface	Reduction of fibrinogen adsorption (%)
15% PEG	76 ± 18
5% PEG	79 ± 11
1.66% PEG	64 ± 11
0.5% PEG	34*
5% PEG after 4 weeks in PBS	89±7%
