Notes: Data are mean values ± SEM; N = 3; #p < 0.01 and ##p < 0.05 compared to uncoated titanium on day 3; *p < 0.05 compared to 0.001 mg/mL RNT–K coated on titanium on day 3; **p < 0.001 compared to respective substrates on day 1; and ***p < 0.001 compared to respective substrates on day 3.
Abbreviations: RNT–K, rosette nanotube–lysine side chain; SEM, standard error of mean.
