“…AgNPs can exist in the form of metallic silver with atoms strongly connected with each other [ 34 ]. The typical AgNPs are usually of a few to a dozen nm in diameter [ 35 ] and can take different shapes (spherical, irregular or planar) [ 9 , 20 , 24 , 25 , 26 , 27 , 28 , 36 , 37 , 38 ] that depend on the methods of production. One of the most popular “bottom up” eco-friendly method is biological synthesis, using living cells of bacteria, fungi and plants to obtain silver nanoparticles [ 9 , 15 , 16 , 17 , 19 , 24 , 27 , 37 , 38 ].…”

Silver is considered as antibacterial agent with well-known mode of action and bacterial resistance against it is well described. The development of nanotechnology provided different methods for the modification of the chemical and physical structure of silver, which may increase its antibacterial potential. The physico-chemical properties of silver nanoparticles and their interaction with living cells differs substantially from those of silver ions. Moreover, the variety of the forms and characteristics of various silver nanoparticles are also responsible for differences in their antibacterial mode of action and probably bacterial mechanism of resistance. The paper discusses in details the aforementioned aspects of silver activity.

“…The necessary conditions for the synthesis of silver nanoparticle composites based on mineral substrates such as quartz [5][6][7][8], talc [9], diatomite [2,10,11], kaolinite [12], montmorillonite [13][14][15][16], zeolite [17][18][19] and mesoporous silica [20,21] have been established. The formation of silver nanoparticles on the surface of mineral substrates can be obtained by ion exchange in silver nitrate solution and further reduction by different methods, such as thermal treatment [16], UV-irradiation, which allows the regulation of the size of nanoparticles by manipulating irradiation parameters [22], methods of hydrothermal synthesis [19] and sonochemical reduction [14,20], as well as by using wet reduction methods [23][24][25][26][27][28][29][30][31][32].…”

. In the present research, hybrid (AgCl, Ag)NPs/diatomite composites were synthesized by direct impregnation with aqueous silver nitrate solutions. The silver chloride nanoparticles (AgCl-NPs) were formed as an effect of the exchange reaction when silver interacted with the diatomite mineral impurity halite. Nanoparticles of metallic silver (AgNPs) were created by the reduction of silver ions under the influence of hydrogen peroxide. The content of silver chloride nanoparticles in the (AgCl, Ag)NPs/diatomite composite was limited by the content of the halite in the used diatomite. Samples of natural diatomite and synthesized (AgCl, Ag)NPs/diatomite composites were examined by using scanning electron microscopy, transmission electron microscopy, X-ray powder diffraction, infrared spectroscopy and thermogravimetric analysis. Moreover, the antibacterial potential of synthesized composites was also studied using the MIC (minimal inhibitory concentration) method against the most common drug-resistant microorganisms in the medical field: Gram-positive Staphylococcus aureus and Gram-negative Klebsiella pneumoniae. The obtained hybrid (AgCl, AgNPs)/diatomite composites were shown to have antimicrobial potential. However, widespread use requires further study by using various microorganisms and additional cytotoxic studies on eukaryotic systems, e.g., cell lines and animal models.
