Impact of palladium nanoparticles on plant and its fungal pathogen. A case study: .

The technological exploitation of palladium or palladium nanoparticles (PdNPs) is increasing, and their wider usage relates to an unwanted release of pollutants into the environment, raising public health concerns about the infiltration of palladium into the consumption chain. This study focuses on the effect of spherical gold-cored PdNPs of 50 ± 10 nm diameter stabilized by sodium citrate on the interaction between an oilseed rape () and the fungal pathogen Pretreatment of cotyledons with PdNPs suspension 24 h before but not 24 h after inoculation with resulted in a decrease in the extent of disease symptoms; however, this effect was caused by Pd ions (35 mg l or 70 mg l). Tests to determine any direct antifungal activity on demonstrated that the residual Pd ions present in the PdNP suspension were responsible for the antifungal activity and that PdNPs themselves do not contribute to this effect.

Noble metal nanoparticles in agriculture: impacts on plants, associated microorganisms, and biotechnological practices.

Within the past decades, nanoparticles (NPs) have become common components of electronics, batteries, cosmetics, clothing, and even dietary supplements. Despite their undisputed advantages consisting in the possibility of engineering their novel physical, thermal, optical, and biological properties, safety questions arise concerning their wide exploitation. NPs interact with living organisms, which can interfere with essential life processes.
