| Abstract Scope |
Metal oxide nanoparticles (NP) are common in the environment originating on weathering of minerals both in marine and freshwater environments and in soil. Their effects on living organisms are important in the view of complex surface chemistry and enhanced surface to volume ratio. In the present contribution three major effects of NP will be considered – (1) their role in mediating interactions between soil microorganisms and plant roots with strong contribution to biofilm formation, (2) the catalytic effects in plant tissues, where NP can act as nanozymes, and (3) specific protein adsorption, resulting in formation of scaffolds for tissue regeneration. Major tools in this work have been X-ray single crystal, NMR and electrospray mass-spectrometry studies of oxide “cluster” models bearing selected biomolecular ligands. |
