The impact of nanomaterial transformations on photosynthetic proteins remains largely unknown. We report positively charged iron oxide (FeO) nanoparticles experience transformations in Arabidopsis thaliana plants in vivo that alter the formation and function of RuBisCO protein corona, a key carbon fixation enzyme. In vitro, negatively charged FeO nanoparticles impact the RuBisCO function but not their positively charged counterparts.

Polysaccharides represent an ideal delivery platform for agrochemicals due to their biodegradability, biocompatibility, and abundance. However, hydrophilicity renders native polysaccharides ineffective at controlling the release of water-soluble agrochemicals. To overcome this limitation, we used a solvent-free, vapor-phase modification strategy to generate hydrophobic shells on the surface of nanofibrillated cellulose (CNF) prills and evaluated the effects of these tunable diffusion barriers on fertilizer release behavior.

Drought stress significantly limits crop productivity and poses a critical threat to global food security. Silica nanoparticles (SiONPs) have shown a potential to mitigate drought stress, but the role of the nanostructure on overall efficacy remains unclear. This study evaluated solid (SSiONPs), porous (PSiONPs), and hollow (HSiONPs) SiONPs for their effects on drought-stressed tomatoes ( L.

Agrochemical delivery is highly inefficient, and novel application methods are necessary to promote crop health and yields while reducing environmental impact. In this work, a vacuum infiltration seed priming strategy was developed to incorporate silica nanoparticles into soybeans. Although successful in initial greenhouse and field studies, little is known about the amount of nutrient being delivered and the conditions for optimum accumulation.

Despite their efficacy, opioids have long been associated with risks of addiction, tolerance, and dependence, leaving an unmet clinical need for pain treatment. Efforts have been devoted to developing novel classes of pain-relieving medication that outperform current options in terms of pain relief, side-effect profiles, and potential for abuse, but with limited success. Recent advances in the neurobiology of pain have shed light on the potential of targeting non-opioid receptors involved in pain processing.

Although the Green Revolution dramatically increased food production, it led to non- sustainable conventional agricultural practices, with productivity in general declining over the last few decades. Maintaining food security with a world population exceeding 9 billion in 2050, a changing climate, and declining arable land will be exceptionally challenging. In fact, nothing short of a revolution in how we grow, distribute, store, and consume food is needed.

Nanoparticles (NPs) have been shown to deliver micronutrients to plants to improve health, increase biomass, and suppress disease. Nanoscale properties such as morphology, size, composition, and surface chemistry have all been shown to impact nanomaterial interactions with plant systems. An organic-ligand-free synthesis method was used to prepare positively charged copper oxide (CuO) nanospikes, negatively charged CuO nanospikes, and negatively charged CuO nanosheets with exposed (001) crystal faces.

  • The study examined how citric acid-coated copper oxide nanoparticles (CuO NPs) affected soybean growth through different application methods (foliar vs. soil).
  • Foliar application of CuO NPs significantly boosted soybean yield by around 170%, while no yield improvement was noted with ionic copper treatments.
  • The results suggest that citric acid coating reduces CuO NPs toxicity, influencing copper accumulation and transfer in the plant, which has implications for food safety and nanoparticle usage.
