One of the most common biominerals on Earth is calcium carbonate, which is formed by various organisms during the process of mineralization. These biominerals have unique properties that differ from inorganic minerals, including their degree of crystallinity, isotopic and trace-element composition, and polymorphic structure. This review will explore the role of bacterial cell walls and extracellular macromolecules in the biomineralization process, as well as present the main hypotheses on how microbial cells and their components initiate this process. Additionally, we discuss the conditions for the formation of a wide range of calcium carbonate polymorphs and their stability within biological systems. Understanding the mechanisms and dynamics of biomineralization is crucial for scientific and technological innovation, as it allows us to better understand microbial ecology and biogeochemical cycles. This knowledge could open up new opportunities for the creation of innovative materials and technologies.","PeriodicalId":716,"journal":{"name":"Nanotechnologies in Russia","volume":"20 6","pages":"682 - 694"},"PeriodicalIF":0.8,"publicationDate":"2026-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147336091","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}

Pt/C and PtCo/C catalysts with different platinum weight fractions on a nitrogen-doped Ketjenblack EC-300J support have been obtained by the liquid-phase synthesis. The transmission electron microscopy study of the catalyst microstructure has shown that both materials exhibit a narrow size distribution of metallic nanoparticles and a low degree of their agglomeration. Study of the electrochemical behavior of the catalysts on a rotating disk electrode has shown that both materials significantly outperform their commercial counterparts in both the electrochemically active surface area and activity in the oxygen reduction reaction. It has been found that the maximum efficiency of a membrane-electrode assembly with the use of the obtained catalysts on the cathode is achieved at an ionomer/carbon weight ratio of 0.9. The peak powers of the membrane-electrode assemblies achieved using this ratio have been 652 and 666 mW/cm2 for mono- and bimetallic catalysts, respectively. The use of the obtained PtCo/C catalyst on the cathode of the membrane-electrode assembly allowed for an increase in its productivity by 8% as compared with its commercial counterpart.","PeriodicalId":716,"journal":{"name":"Nanotechnologies in Russia","volume":"20 6","pages":"769 - 778"},"PeriodicalIF":0.8,"publicationDate":"2026-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147336234","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 initial amorphous oxide films have been subjected to heat treatment at 400, 450, and 500°C. The effect of the annealing temperature on the structural and I–V characteristics has been comprehensively studied. It has been shown that annealing at 400°C for 30 min leads to the formation of the anatase (TiO2) phase with a fraction of up to ~98%. The sample microstructure exhibits a high degree of ordering and uniformity of the TiO2 array vertically aligned relative to the substrate. The average nanotube inner diameter is approximately 50–60 nm and the nanotube wall thickness is 10–15 nm. Raman spectra of the samples have revealed the main vibrational modes Eg, Eg, B1g, A1g, and Eg corresponding to the anatase (TiO2) phase. The calculated O–Ti–O bond lengths ranging from 1.89 to 2.85 Å are typical of a distorted TiO(_{6}^{{8 - }}) octahedron. The I–V characteristics of the films are nonlinear and typical of oxide materials with the resistance switching effect.

The object of study is the anti-Müllerian hormone, a biomarker of the state of the female reproductive system. Two methods of antibody immobilization are considered: high-affinity streptavidin–biotin binding and physical adsorption. Oriented immobilization demonstrates the absence of nonspecific interactions and an increase in assay sensitivity. An increase in the size of nanoparticles in the immunoconjugate leads to a decrease in the limit of detection. The identified patterns make it possible to develop a test system with a hormone detection limit of 0.1 ng/mL and a working range of 1.0–42.1 ng/mL. The possibility of using the test system in fivefold diluted blood serum is demonstrated.","PeriodicalId":716,"journal":{"name":"Nanotechnologies in Russia","volume":"20 6","pages":"821 - 830"},"PeriodicalIF":0.8,"publicationDate":"2026-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147336085","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}

Due to their smaller diameter (199 fold) and higher degree of sphericity (1.45 fold) compared with microparticles, nanoparticles are accumulated at a higher concentration (up to 1.45 fold) in the lungs, heart, and liver of rats upon repeated oral exposure to a total dose of 16 625 mg/kg of body weight over 24 days, which determines a higher degree of material accumulation. Increased bioaccumulation leads to the more pronounced (up to 2.29 fold compared with the effect of microparticles) development of oxidative stress, cytolysis, impaired thrombocytopoiesis, and the development of an inflammatory response and imbalance of neurotransmitters at the cellular and molecular levels. At the organ and tissue levels, pathomorphological necrotic changes develop in lung tissues (fibrinopurulent pneumonitis) and inflammatory disorders in bronchial tissues (panbronchitis) are more pronounced upon exposure to ZnO nanoparticles as opposed to the effect of microparticles. Disorders at the cellular, molecular, organ, and tissue levels confirm the more pronounced functional accumulation of ZnO nanoparticles compared with microparticles. The research results prove the more pronounced material and functional accumulation of ZnO nanoparticles compared with their microsized chemical analog.
