Device toxicity assessment. A The results of the CCK-8 assay revealed no significant statistical difference in cell viability between the two groups at days 1, 3, 5, and 7 of cell culture. B The cell counting results demonstrated no significant statistical difference in cell numbers between the two groups at days 1, 3, 5, and 7 of cell culture. C The BCA assay results indicated no significant statistical difference in total protein content between the two groups at days 1, 3, 5, and 7 of cell culture
