Fourier-transform infrared (FTIR) spectra of the materials are shown for (A) Chr, (B) Qur, (C) a physical mixture of Chr–Qur, and (D) Chr–Qur@MSNs–Chi nanoparticles. The spectra display the characteristic functional group vibrations of Chr and Qur, while the shifts and appearance of new peaks in the Chr–Qur@MSNs–Chi sample confirm successful drug loading and interactions with the chitosan-coated mesoporous silica framework.
