Surface and structure design of aminosilica nanoparticles for multifunctional applications: adsorption and antimicrobial studies

Abstract The chapter is a self-review devoted to features of synthesis and structure of spherical particles functionalized with amino-containing groups, which are produced by the sol-gel method. This review consists of three main parts in addition to introduction and conclusions. The first part deals with the features of the synthesis techniques, identification of the functional groups and silica skeleton by vibrational spectroscopy and with the structure of particles and their surfaces on the basis of the physical and chemical methods. In the second part, the sorption properties of functionalized silica particles towards copper(II) ions and some anionic dyes are discussed and analyzed. Finally, in the third part, the cause of antibacterial properties of amino-as well as copper-amino-containing materials was highlighted, including overview of data by other authors.
