Cieľom štúdie bolo zmapovať postoje voči nanotechnológiám. Zaujímalo nás, ako jednotlivé faktory zasahujú do formovania postojov, pričom sme sa zamerali na vplyv miery informovanosti a dôvery voči informáciám zo strany odborníkov. Skúmali sme, aké sú rozdiely vo vnímaní rizík a benefitov nanotechnológií medzi pohlaviami, a akú rolu zohráva religiozita. Dáta sme zbierali prostredníctvom dotazníka a fókusových skupín. Kvantitatívnej časti výskumu sa zúčastnilo 189 participantov a kvalitatívnej časti za zúčastnilo 18 participantov. Výsledky výskumu potvrdili súvis medzi dôverou voči informáciám zo strany odborníkov a postojmi voči nanotechnológiám, ako aj súvis medzi mierou informovanosti a postojmi voči aplikáciám nanotechnológií v medicíne. Participanti vnímali medicínu ako oblasť, v ktorej môžu nanotechnológie priniesť najväčšie pokroky, zatiaľ čo za oblasť s najväčším počtom rizík považovali oblasť obrany a národnej bezpečnosti.Klíčová slova: percepcia rizík a benefitov; nanomedicína; postoje; dôvera voči vede; obsahová analýza.

“…Nanotechnology is a source of numerous beneficial solutions, including in agriculture (Gorczyca et al, 2021a, Shao et al, 2022, and simultaneously one of the important civilizational threats of the modern world (Allan et al, 2021). This phenomenon can be compared to the problem of genetically modified organisms, but nanotechnology was quickly accepted by society and does not raise so many controversies (Murphy et al, 2022). Agriculture has already adopted numerous nanotechnologies in key practices for sustainable intensification, such as fertilization and plant protection.…”

The aim of the experiments was to evaluate shifts in the prokaryotic and eukaryotic microbiome of maize rhizoplanes treated with five forms silver nanoparticles with different surface properties, produced by chemical reduction of silver(V) nitrate. Metagenomic studies were performed using appropriate procedures to create NGS libraries and sequences to species. All silver nanoparticles forms used moderately limited the growth of maize, without significantly affecting normalized difference vegetation indexes. Significant shifts in the taxa of the microbiome while preserving biodiversity were noted under the influence of silver nanoparticles, and the reaction of bacteria and eukaryotes was different. The eukaryotic microbiome, richer in the studied substrate, turned out to be more sensitive, showing greater qualitative and quantitative changes than the bacteriome. silver nanoparticles did not reduce the occurrence of mycorrhizal fungi, enriched the occurrence of Acidobacteriota and, with the exception of trisodium citrate reduction/sodium borohydride stabilization type, enriched the beneficial bacteria of Devosia. Within silver nanoparticles, distinct effects have been demonstrated for type with trisodium citrate reduction/sodium borohydride stabilization versus cysteamine reduction/trisodium citrate stabilization versus group: hydroxylamine hydrochloride reduction, tannic acid reduction and trisodium citrate reduction. The beneficial changes in maize rhizoplane microbiome can be attributed special to silver nanoparticles reduced using hydroxylamine hydrochloride.K e y w o r d s: maize, soil, microbiome, silver nanoparticles

(Re)Conceptualizing decision-making tools in a risk governance framework for emerging technologies—the case of nanomaterials

The utility of decision-making tools for the risk governance of nanotechnology is at the core of this paper. Those working in nanotechnology risk management have been prolific in creating such tools, many derived from European FP7 and H2020-funded projects. What is less clear is how such tools might assist the overarching ambition of creating a fair system of risk governance. In this paper, we reflect upon the role that tools might and should play in any system of risk governance. With many tools designed for the risk governance of this emerging technology falling into disuse, this paper provides an overview of extant tools and addresses their potential shortcomings. We also posit the need for a data readiness tool. With the EUs NMP13 family of research consortia about to report to the Commission on ways forward in terms of risk governance of this domain, this is a timely intervention on an important element of any risk governance system.
