Western Blot results of NO related proteins. a The Akt protein expression level was upregulated on 10, 100 nm nanodot arrays after day 1 incubation. b The eNOS expression levels were significantly enhanced on 200, 100 and 50 nm nanodot arrays after day 1, 3, 5 incubation. c The iNOS expression levels were upregulated on 100 nm nanodot arrays after 1 day incubation and on 50, 100, 200 nm nanodot arrays for day 3, 5 incubation. d The activities of NF-kB-p65 (p-p65/p65) were downregulated on 10 and 100 nm nanodot arrays for day 1, 3 incubation period and were downregulated on 50, 100 and 200 nm nanodot arrays after incubation for day 5. *shows p < 0.05, while **shows p < 0.01. The mean ± SD from at least 3 experiments is shown
