a Quantitative analysis of surface calcium deposition presenting % of surface covered by co-localised Ca and P (from SEM). Data are reported as mean ± SD (n = 3). One-way ANOVA (α = 0.05) P < 0.0001 for both gels containing CNTs; Tukey’s multicomparison test, ***P < 0.001 compared to control at time zero, ### P < 0.001 compared to a specific sample as indicated in the figure. b Average % salt deposition on different types of hydrogel samples (from microCT). Data are reported as mean ± SD (n = 5). One-way ANOVA (α = 0.05) P < 0.0001 for both gels containing CNTs, Tukey’s multicomparison test, all samples presented P < 0.001 compared to control, and P < 0.001 was obtained for all comparisons between 7 and 14 days. Release profile of c BSA d OVA from (black closed circle) chitosan; (red closed square) CS-HACS-(NOSC-SWNTs); (blue closed triangle) CS-HACS-(NOSC-MWNTs) gels. Data are reported as mean ± SD (n = 3) (Color figure online)
