a FTIR spectra of TA, MSN and MSN-TA nanocontainers; b N2 adsorption-desorption isotherm and pore diameter distribution (inset) of MSN and MSN-TA; c TGA curves of TA, MSN and MSN-TA nanocontainers; d the UV-Vis spectra and the corresponding standard curves (inset) of TA in 3.5 wt.% NaCl solutions; e the UV-Vis spectra of TA released from MSN-TA nanocontainers in 3.5 wt.% NaCl solutions after different release time; f the release percentage of TA from MSN-TA in 3.5 wt.% NaCl solutions. The insets are the TEM images of MSN-TA nanocontainers before and after 600 min of release (scale bar: 100 nm).
