However, it results in the formation of nanoparticles and microparticles containing toxic metals (such as Cr, Cu, Pb, and Mn) that pose a threat to marine ecosystems. This study evaluated the effect of particles produced by different underwater welding methods (wet welding and flux-cored wire and coated electrode cutting) on the embryonic development of the sea urchin Strongylocentrotus intermedius. Experiments were conducted using welding suspensions at 1 and 10% concentrations to simulate real contamination conditions. The results revealed a notable reduction in embryo viability at every developmental stage (from the initial divisions to the gastrula stage), particularly at high concentrations. Particles from powdered wire (APL-2) and coated electrodes (ELw, ELc) were found to be the most toxic, which correlated with their increased heavy metal content. Exposure to welding particles was found to result in the following: \u0000• increased embryo death (up to 11.5% at the blastula stage in the ELc group vs. 5.93% in the control group); \u0000• disruption of cell division and morphological abnormalities; \u0000• cumulative toxic effects that increase over time. \u0000The findings emphasize the need to develop environmentally safe welding technologies and strengthen pollution monitoring in areas of active underwater activity. The study contributes to our understanding of the mechanisms behind the toxic effects of anthropogenic particles on marine organisms and can serve as a basis for environmental regulations.","PeriodicalId":716,"journal":{"name":"Nanotechnologies in Russia","volume":"20 1","pages":"S227 - S234"},"PeriodicalIF":0.8,"publicationDate":"2026-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147606465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the white poplar × aspen hybrid, the use of nanoflakes at a concentration of 10 mg L–1 was optimal for sterilization and stimulation of multiplication, while for birch, nanospheres at concentrations of 10–100 mg L–1 were optimal for reducing contamination. White poplar × aspen exhibited higher resistance to the effects of CuO NPs, whereas birch was more sensitive to NP exposure.

Their feasibility for industrial-scale synthesis and unique catalytic properties open up broad prospects for applications in various sectors of the bioeconomy. This review summarizes recent advances and key application areas of nanozymes, ranging from enhancing the bioavailability of feed additives to their use in veterinary practice and human medicine, including antiviral therapy, wound healing, regenerative technologies, cryopreservation, and antitumor treatment. The advantages of nanozymes over protein enzymes are discussed, and current challenges related to the standardization of evaluation methods and the assessment of long-term biological effects are highlighted. Overall, the analysis demonstrates that nanozymes have the potential to become a pivotal tool in the development of sustainable agriculture, environmental protection, and biomedical technologies, as well as in ensuring food and technological security. This review aims to stimulate further research in nanotechnology and biomaterials science and to promote the translation and practical implementation of nanozymes in advanced technologies and applications in Russia.","PeriodicalId":716,"journal":{"name":"Nanotechnologies in Russia","volume":"20 1","pages":"S62 - S71"},"PeriodicalIF":0.8,"publicationDate":"2026-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147606363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment is conducted under controlled conditions. The effect of NPs on the growth, development, yield elements, and biochemical parameters of barley plants under various irrigation regimes in the tillering and earing phases is evaluated. The results show that the treatment of seeds with NPs has a complex effect on plants, depending on water availability and the phase of development. Under conditions of sufficient moisture, the NPs contribute to an increase in the number of stems and grains per ear by 20 and 16%, respectively, as well as development of the root system. However, when there is a shortage of moisture, the effect of NPs is more complex, manifesting itself in changes in plant height, the number of grains, and the grain weight per ear. Biochemical analysis reveals that under conditions of limited irrigation, the level of lipid peroxidation (LPO) increases relative to the control by 20 and 16%. The accumulation of polyphenols and flavonoids increases similarly (by 50.7 and 52.3%, respectively). The presowing treatment of seeds with NPs contributes to a change in these indicators, which affects the antioxidant protection of plants under stress. Thus, the presowing treatment of spring barley seeds with Mn, Zn, and Cu NPs can have a positive effect on plant growth and productivity under conditions of both sufficient and limited moisture. However, the effect of NPs depends on the phase of plant development and the degree of water deficiency, which underscores the need for further research to optimize the use of nanopreparations in agriculture. The observed effect shows that this method is promising for increasing the drought resistance and yield of crops. Further research is needed to develop optimal application schemes based on agroclimatic conditions.","PeriodicalId":716,"journal":{"name":"Nanotechnologies in Russia","volume":"20 1","pages":"S211 - S218"},"PeriodicalIF":0.8,"publicationDate":"2026-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147606464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laboratory and field trials demonstrated a significant improvement in seed germination, seedling growth, and grain quality following the nanopriming of winter wheat seeds. Nanoparticles of zinc (Zn 1 ppm), copper (Cu 0.00001 ppm), and a composite formulation (Fe 1 ppm + Zn 1 ppm + Cu 0.0001 ppm + Mn 0.01 ppm) enhanced seed germination by 2, 4, and 4%, respectively. Treatment with nanopreparations containing individual NPs (Fe, Zn, Cu) increased seedling dry biomass by 38–49%. Manganese nanoparticles (0.1 ppm) produced the maximum gain (+64%). Root dry mass increased by 144% (Cu NPs 0.001 ppm), shoot height by 20% (Fe NPs 1 ppm, Cu NPs 0.001 ppm), and the length of adventitious roots by 24–60%, depending on the NP type. The quality of wheat grain from seeds treated with nanopreparationswas also improved: crude gluten content increased by 5–6% (Fe NPs 1 ppm, Cu NPs 0.001 ppm), protein content by 2–5%, and vitreosity by 1–2%. Grain moisture decreased from 12.1% (control) to a range of 9.8% (Zn NPs 1 ppm) to 10.7% (Composite NPs). Seed treatment with Zn NPs (1 ppm) reduced Fusarium infestation of grain by 2.25 times, while the composite NPs reduced it by 33%. The obtained results demonstrate the high potential of pre-sowing nanopriming for improving the yield and quality of winter wheat.","PeriodicalId":716,"journal":{"name":"Nanotechnologies in Russia","volume":"20 1","pages":"S219 - S226"},"PeriodicalIF":0.8,"publicationDate":"2026-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147606402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
