The advancement in nanotechnology has enabled a significant expansion agricultural production. Agri-nanotechnology is an emerging discipline where nanotechnological methods provide diverse nanomaterials (NMs) such as nanopesticides, nanoherbicides, nanofertilizers and different nanoforms of agrochemicals for management. Applications nanofabricated products can potentially improve the shelf life, stability, bioavailability, safety environmental sustainability active ingredients sustained release. Nanoscale modification bulk or surface properties bears tremendous potential effective enhancement productivity. As NMs tolerance mechanisms plants under stressful conditions, they are considered promising tools to overcome constraints sustainable For their exceptional qualities usages, nano-enabled developed enforced, along with agriculture, sectors. rampant usage increases release into environment. Once incorporated environment, may threaten stability function biological systems. Nanotechnology newly technology, so evaluation associated risk pivotal. This review emphasizes current approach synthesis, application interaction plant-soil microbes challenges address future applications maintaining

Selenium (Se) is a nutritional component necessary for animal and plant development reproduction. nanoparticles (SeNPs) have high absorption rate during routine supplementation. In the current study, cell-free extract of Aspergillus terreus was used as reducing stabilizing agent in synthesis SeNPs using green eco-friendly method. The mycosynthesized were characterized by UV-visible spectrophotometry, Fourier transform infrared spectroscopy, X-ray diffraction dynamic light scattering, transmission electron microscopy, scanning microscopy. results characterization process showed that had spherical shapes sizes less than 100 nm. Results exhibited promising antibacterial activity against both Gram-positive Gram-negative bacteria where inhibition zones 14, 20, 16, 13 mm toward S. haemolyticus, aureus, E. coli, K. pneumoniae, respectively. However, it weak antifungal C. albicans, zone 12 mm. efficacy decolorization malachite dye investigated. illustrated rapid biodegradation dye, reaching up to 89% after 240 min. conclusion, successfully biosynthesized A. demonstrated antimicrobial photocatalytic activities.

Selenium (Se), a component of selenoproteins and selenocompounds in the human body, is crucial for development male reproductive organs, DNA synthesis, thyroid hormone, metabolism, defence against infections oxidative damage. In testis, it must exceed desirable level since either shortage or an overabundance causes aberrant growth. The antioxidant properties selenium are essential preserving health. Selenoproteins, which have important structural enzymatic properties, control biological activities Se primarily. These proteins specifically role metabolism variety cellular processes, such as transport, hormone immunity, redox balance. nanoparticles (SeNPs) less hazardous than selenium-based inorganic organic materials. Upon being functionalized with active targeting ligands, they both biocompatible capable efficiently delivering combinations payloads to particular cells. this review, we discuss briefly chemistry, structure functions milestones selenoproteins. Next various factors influences infertility, selenoproteins, spermatogenesis fertility. Furthermore, molecular mechanism transport protective effects on stress, apoptosis inflammation. We also highlight critical contribution fertility spermatogenesis. Finally ends conclusion future perspectives.

Drought stress poses a significant obstacle to agricultural productivity, particularly in the case of oilseed crops such as sunflower ( Helianthus annuus L.). Selenium (Se) is fundamental micronutrient that has been recognized for its ability enhance plant resilience face various environmental stresses. The FH-770 variety was cultivated pots subjected three levels (100% FC, 75% and 50% FC) four Se application rates (0 ppm, 30 60 90 ppm). This research aimed investigate effect exogenously applied on morpho-physiological biochemical attributes improve drought tolerance. Foliar significantly lowered H 2 O (hydrogen peroxide; ROS) (20.89%) accumulation markedly improved glycine betaine (GB) (74.46%) total soluble protein (Pro) (68.63%), ascorbic acid (AA) (25.51%), phenolics (TP) (39.34%), flavonoids (Flv) (73.16%), anthocyanin (Ant) (83.73%), activity antioxidant system superoxide dismutase (SOD) (157.63%), peroxidase (POD) (100.20%), catalase (CAT) (49.87%), which ultimately growth by 36.65% during stress. Supplemental increased shoot content (93.86%) calcium (Ca 2+ ), potassium (K + sodium (Na ) ions roots 36.16%, 42.68%, 63.40%, respectively. supplements at lower concentrations (60 ppm) promoted growth, development, sunflowers controlled water-deficient circumstances. However, selenium treatment photosynthetic efficiency, enzymatic activities, osmoregulation, characteristics, nutrient balance. mechanisms molecular processes through induces these modifications need further investigation be properly identified.

Discovered in mid-1817 by Jöns Jacob Berzelius, selenium, belonging to Group 16 of the periodic table is an essential trace element for human and animal health, due its biocompatibility bioavailability. Additionally, it known having different oxidation states, which allows interact with distinct chemical elements form various compounds. Selenium exhibits two forms, organic inorganic; latter genotoxicity. nanoparticles have been investigated as alternative mitigate toxicity this element. With antidiabetic, antiviral, chemopreventive, antimicrobial properties, SeNPs possess significant biomedical potential can be synthesized using chemical, physical, or green methods, offering new solutions combating microbial resistance other diseases. This review discusses historical discovery preparation versatility combinations synthesis, morphological characteristics, sizes, well impact SeNP applications obtained through approaches against medically relevant microorganisms, particularly those exhibiting conventional antimicrobials.

Topical cariostatic agents have become a reasonable alternative for managing dental caries in young children. Silver diamine fluoride (SDF) is practical topical approach to arrest and avoid extensive risky treatment. However, the literature demonstrates parental hesitation towards accepting SDF because of black unaesthetic tooth discolouration following application. The rapid oxidation ionic silver darkens demineralised structure permanently. In this regard, nano-metallic antimicrobials could augment or substitute silver, thereby enhance aesthetic performance. Recently, biomedical research has drawn attention selenium nanoparticles (SeNPs) due their antimicrobial, antioxidant, antiviral potencies. Various vitro studies examined effect SeNPs on virulence bacteria. This narrative review explores issues when using suggests future directions develop it, focusing antimicrobial metals. Several methods are described that be followed reduce concern, including use fluoride, other metals with actions. There also value remineralising than such as NPs hydroxyapatite. variations made formulations order lower levels even replace one both components completely. Moreover, since processes appear central chemistry staining, adding which antioxidant actions an anti-staining benefit; used well. Future should address topic optimise how would place silver. Incorporating explored, taking into account optimal physicochemical parameters each these.
