“…The most recent application of AG as a stabilizing polymer matrix in hybrid nanosized materials is based on iron oxides, cobalt, copper, nickel, ferrites and zero-valence metals such as silver, palladium and platinum [18,[55][56][57]. Metal content in nanocomposite samples depends on synthetic conditions and on the type of metal ion used, varying in the range of 0.1-21.0%.…”

“…The interest of researchers into various antiseptic nanocomposites is currently growing [5][6][7][8]; the powerful antimicrobial properties of these substances may be related to the nature of the nanoparticles, as well as to the use of specific bacteriotropic polymers (such as β-polysaccharides serving as trophic substrates for bacteria) for the production of nanocomposites [9][10][11][12][13][14][15]. Antimicrobial nanocomposites enabling the targeted trophic delivery of nanoparticles to microbial cells can be produced using such polymers [16].…”

A novel selenium nanobiocomposite consisting of X-ray amorphous nanoparticles of red elemental selenium (average size ~67 nm) uniformly encapsulated into arabinogalactan macromolecules has been synthesized. The effect of this nanobiocomposite and its precursors (pure arabinogalactan and selenium dioxide) on the viability of a phytopathogenic bacterium Clavibacter michiganensis subsp. sepedonicus (Spieck et Kotth.) Skapt et Burkh (C. michiganensis) and potato plants has been investigated in vitro. The bactericidal effects of free selenium dioxide and the nanocomposite obtained from the former (normalized selenium concentration 0.000625%) have been demonstrated. The targeted metabolic (trophic) delivery of antimicrobial selenium nanoparticles to the bacterial cells by the arabinogalactan matrix incorporating the particles was detected in the latter case. The treatment of potato plants with selenium dioxide was found to have a negative effect on peroxidase activity and plant growth. On the contrary, treating the plants with the selenium nanocomposite had no negative effects. Thus, the nanocomposite of elemental selenium and arabinogalactan produced in the present work can be considered a new antimicrobial agent for plant sanitation with minimal side effects.

“…In this connection, the use of hybrid organic-inorganic nanocomposite of the potentially antimicrobial elemental selenium (NCSe) [5][6][7], obtained on the basis of natural heteropolysac charide arabinogalactan, an effective stabilizer of nanoparticles of different natures [8][9][10], can be a very promising disinfecting agent.…”
