Preparation of amino silane magnetic nanocomposite by the sol-gel process and investigation of its antibacterial activity

The results of a comparative investigation on microstructure and magnetic characteristics of silane magnetic nanocomposites coated with silver nanoparticles (AgNPs) are presented. The authors used tetraethyl orthosilicate (TEOS) with (3-aminopropyl) triethoxysilane (APTES) to improve the antibacterial properties of AgNPs. On the basis of this approach, TEOS-APTES polymer was made by the sol–gel method. A layer of the polymer was set on the magnetic core of Fe3O4 NPs and then AgNPs were coated on the TEOS-APTES surface. Therefore, the core–shell structure of the Fe3O4/TEOS-APTES/Ag polymer nanocomposite was synthesised. To characterise the crystal morphology, structure, and size of nanocomposites, various techniques and experiments including Fourier transform infrared spectroscopy, X-ray diffraction, field-emission scanning electron microscope, dynamic light scattering, and transmission …
