Microstructure and surface chemistry characterisation of the samples. (a) FE-SEM images of TiO2-NT, NT-Sr1h, and NT-Sr3h. The scale bar represents 500 nm. (b) XRD pattern of NT-Sr1h. (c) XPS survey spectra of NT-Sr1h. (d) Release of Sr from NT-Sr1h and NT-Sr3h into PBS at different time points. (e) Total Sr content of NT-Sr1h and NT-Sr3h, **p < 0.01. At least three independent experiments were analysed, and the data are presented as the means ± SDs.
