This study describes the amino-functionalization of the MCM-41 mesoporous matrix by post-synthesis grafting using 3-aminopropyltriethoxysilane (APTES) and the characterization of amino-functionalized mesoporous silica MCM-41 loaded with magnolol (MGN) in order to achieve modified drug delivery systems. The aminofunctionalization of silica MCM-41 with three different levels in the number of the amino groups introduced was carried out by grafting in a field of ultrasound. MCM-41 shows a one-dimensional system of the...
