Both mesoporous materials, MCM-41 and MCM-48, used as a support for functionalization and further loading, were synthesized using the soft template method starting from proper ratio of TEOS and CTAB (Figure 1 ). The synthesis was carried out under the same conditions, the working conditions being described in our previous work [49 (link)].
The functionalization of mesoporous silica was done following the method [50 (link)], using (3-aminopropyl)triethoxysilane as coupling agent. One gram of each mesoporous material (MCM-41 and MCM-48), was dried in the vacuum drying oven at a temperature of 23 °C for 3 h. After drying, 100 mL ethanol was added and the suspensions were sonicated for one hour. 125 μL of APTES was added to each suspension and left to reflux for 24 h and sonicated for one hour. The obtained suspensions were filtered and left to dry.
