(a) XRD analysis showing a peak intensity for MSNs and PIP-MSNs at 2θ of 2.09°. (b) FTIR spectroscopy of MSNs, PIP, and PIP-MSNs. (c) UV-Vis spectrophotometry of MSNs and (d) PIP-MSNs. As depicted, PIP-MSNs showed a peak absorbance at 340 nm, comparable to PIP’s maximum absorbance. (e) The cumulative release profile of PIP in PBS (pH 7.4) over 20 h and (f) 72 h. The samples were incubated at 37 °C and 120 rpm (n = 3).
