| Description
| - High application potential of nanocomposite materials is rooted in the combination of unique properties of their individual components into one final material. Frequently, it can be formed by a bulk matrix in the form of microparticles and active nanostructured that are anchored into the matrix to form the composite. This combination of micro- and nanostructured materials results into improvement of e.g. mechanical properties and makes the manipulation with the nanoparticles (NPs) easier. Silicate materials, such as clay minerals or zeolites, are frequently used as the inert support for metal NPs. Therefore, this study is aimed on the preparation of the composite materials based on silicate materials and incorporated silver NPs. Aqueous dispersion of silver NPs, with the average diameter of approx. 30 nm, was prepared using a modified Tollens process. These silver NPs were adsorbed from the primarily prepared aqueous dispersion on the montmorillonite and several types of synthetic zeolites. Antibacterial activity of the prepared nanocomposites was tested using a micro-dilution method. The obtained results showed that the antibacterial activity of the silver NP containing composite is only slightly influenced by their incorporation/adsorption into/on this type of an inert support. However, incorporation/adsorption of the silver NPs into/on these silicate materials is rather weak as approx. 20-30% of the adsorbed silver could be released just by the performed washing of the as-prepared composites in distilled water.
