This review summarizes current scientific data on the use of monolayers to model the IMM, with an emphasis on the role of cardiolipin, a unique phospholipid with four acyl chains and two phosphate groups, which plays a key role in IMM structure formation and in the function of oxidative phosphorylation enzymes, and possibly in stabilizing protons at the interface and in their transfer from proton pumps to ATP synthase. The review discusses the advantages of monolayer systems over classical models: the ability to control the degree of lipid compression, the larger interfacial area, and compatibility with almost all detection methods. The key features of cardiolipin in monolayers are described in detail: conical molecular geometry, pH-dependent phase transitions, sensitivity to divalent cations (in particular, calcium), domain formation, and interactions with other components of the membrane/monolayer. Despite the good applicability of monolayer systems, limitations arise because the one-dimensional structure of a monolayer cannot fully reproduce IMM properties. A strategy for further development of monolayer model systems is proposed, including the use of lyso-forms of cardiolipin to optimize molecular geometry, the control of oxidative damage to polyunsaturated lipids, experiments at low pH and physiological ion concentrations, and the application of modern methods for proton generation at the interface (photoacids, or molecules that release protons upon illumination).","PeriodicalId":716,"journal":{"name":"Nanotechnologies in Russia","volume":"20 1","pages":"S44 - S54"},"PeriodicalIF":0.8,"publicationDate":"2026-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147606362","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}

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}
