Abstract In recent years, nanotechnology has had a profound impact on low-temperature preservation, offering advanced solutions that significantly improve the storage of biological samples. Low-temperature preservation is crucial for numerous fields, such as medicine, agriculture, and research, where maintaining viability integrity cells, tissues, organs over extended periods essential. Integration into protocols represents significant advancement, enabling more effective, safer, efficient specimens. Moreover, it affords effective strategies solving one most pressing challenges in transplantology cryobiology today – cryopreservation whole organs. This not only enhances cryopreserved materials but also broadens scope their applications science medicine. article traditional review summarizes limitations methods systems animal origin current advances nano-assisted technologies aimed at overcoming them. We have made every effort to accurately detail role inorganic nanoparticles enhancing field cryobiology, paying special attention application various specifically hypothermic storage, slow-freezing cryopreservation, vitrification. Finally, are critically assessed perspectives discussed.

Nanoparticles (NPs) and their fabrication routes are intensely studied for wide range of application in optics, chemistry, medicine. Γ-ray ion irradiation precursor matter established methods that facilitate tailored NP synthesis without complicated chemistry. Here, we develop explore based on irradiating microparticles with low-energy electron beams. We specifically demonstrate the plasmonic gold nanoparticles sizes between 3 350 nm an amorphous SiO x substrate using a 30 kV beam. By detailed comparison scattering simulations thermodynamic modeling, reveal dominant role inelastic electron-matter interaction subsequent localized heating observed vaporization microparticles. This general principle suggests suitability electron-beam synthesizing NPs class materials.

Nanoparticles are small structures that differ in terms of their shape and composition; high surface-to-volume ratio is responsible for unique properties make them perfect mediators the delivery substances. do not only include metallic spheres but also complex polysaccharides capsule viruses or bacterial protein complexes (which can be considered bionanoparticles), which 1–100 nm size. Although nanoparticles most widely studied from medical perspectives, potential applications almost limitless. One such promising use functional plant protection against diseases. precise decreases need other chemical compounds, thanks to increased product stability a target site, production often burdened by large quantities toxic wastes. This problem limited if we apply bioreactor green synthesis method, includes with microorganisms. Bacteria produce internally, externally, producing metabolites used nanoparticle directly, e.g., surfactants, indirectly as reducing agents metal production. Regardless source nanoparticles, they processes disease/pathogen detection disease suppression. The endless variety materials possible modifications subjected makes it impossible predict how will future. Nevertheless, this study, would like turn attention fact although viewed synthetic structures, ever-present microbial world play an important part intermicrobial interactions. As usefulness has been tested over years co-evolution, may useful look future directions fascinating technology.

Moringa oleifera is also known as miracle tree because of it’s nutritional and physiological benefits. In this research, structural biochemical characterization oleifera’s extracts nanoparticles were done. n-hexane, methanolic aqueous extract M. was prepared by microwave assisted method. The obtained percentage yield the highest (8.86%). Chitosan based ionic gelation method that almost 100nm in size with positive charge on it. Biochemical assessed antioxidant (total phenolic content, total flavonoid content DPPH radical scavenging assay), anti-diabetic (alpha amylase inhibition cytotoxic (percentage hemolysis) anti-inflammatory (albumin denaturation method) activities. One-way ANOVA used for analysis data. comparison between nanoparticles, it observed less toxic (1.99±0.86%) showed higher (65.67±0.26%), (85.87±6.64%) potential (83.55±0.76%). Different functional groups identified fourier transform infrared spectroscopy such primary secondary amines, amides, carboxylic acid, alkanes, aldehyde, alkene, alcohol, ether, ester sulphates. High performance liquid chromatography confirmed presence kaempherol, p-coumaric salicylic acid chlorogenic acid.

Cerium oxide nanoparticles (CeO2 NPs) have gained significant attention in various fields, including biomedicine, semiconductors, cosmetics, and fuel cells, due to their unique physico-chemical properties. Notably, green-synthesized CeO2 NPs demonstrated enhanced potential as drug carriers, particularly biomedical applications such anti-inflammatory, anticancer, antimicrobial, anti-oxidant therapies. This study aimed investigate the anticancer effects of cerium synthesized using turmeric rhizomes on human lung cancer cells. The cytotoxicity proliferation inhibition these were assessed MTT Live/Dead assays, revealing a dose-dependent reduction cell viability. Additionally, reactive oxygen species (ROS) generation was quantified through ROS confirming oxidative stress induction key mechanism cytotoxicity. Cell analysis further that increasing concentrations significantly reduced multiplication healthy These findings highlight turmeric-derived promising therapeutic agent for treatment, warranting exploration action vivo efficacy.
