Biocompatibility of floating beads. The bead amounts in culture medium were 0.5, 1 and 1.5 mg/ml, respectively. Floating beads are core-shell beads with C/X = 4/3. TCPS was tissue culture polystyrene which was used as the controlled group. The culture period was 24 h. From ANOVA test, there was no statistical difference (p > 0.05 and n ≥ 4). From t test, all the core-shell bead groups were not significantly different from TCPS (p > 0.05 and n ≥ 4)
