Selenium nanoparticles as a nutritional supplement

TL;DR: In this article, the effects of the addition of macro-and nanonutrients to soil, the interaction, and the absorption capability of the plants, the environmental effect and food content of the nutrients.

TL;DR: In this article, the main origin of selenocysteine intake, its role on the human body, and its primary biomedical applications are revised, focusing on the main therapeutic targets that are explored for SeNPs in cancer therapies, discussing the different functionalization methodologies used to improve SENPs stability, while enabling the extensive delivery of drug-loaded SeNP to tumor sites, thus avoiding off-target effects.

Abstract: Thanks to low costs and the abundance of the resources, sodium‐ion (SIBs) and potassium‐ion batteries (PIBs) have emerged as leading candidates for next‐generation energy storage devices. So far, only few materials can serve as the host for both Na+ and K+ ions. Herein, a cubic phase CuSe with crystal‐pillar‐like morphology (CPL‐CuSe) assembled by the nanosheets are synthesized and its dual functionality in SIBs and PIBs is comprehensively studied. The electrochemical measurements demonstrate that CPL‐CuSe enables fast Na+ and K+ storage as well as the sufficiently long duration. Specifically, the anode delivers a specific capacity of 295 mA h g−1 at current density of 10 A g−1 in SIBs, while 280 mA h g−1 at 5 A g−1 in PIBs, as well as the high capacity retention of nearly 100% over 1200 cycles and 340 cycles, respectively. Remarkably, CPL‐CuSe exhibits a high initial coulombic efficiency of 91.0% (SIBs) and 92.4% (PIBs), superior to most existing selenide anodes. A combination of in situ X‐ray diffraction and ex situ transmission electron microscopy tests fundamentally reveal the structural transition and phase evolution of CuSe, which shows a reversible conversion reaction for both cells, while the intermediate products are different due to the sluggish K+ insertion reaction.

TL;DR: This first study to report the synergistic antibacterial activity of selenium nanoparticles and lysozyme and nanohybrid system to overcome the emerging antibiotic resistance and define fruitful applications in biomedicine and food safety.

TL;DR: This Review focuses on recent progress important for the rational design of such nanoparticles and discusses the challenges to realizing the potential of nanoparticles.

TL;DR: The crucial factor that needs to be emphasised with regard to the health effects of selenium is the inextricable U-shaped link with status; whereas additional seenium intake may benefit people with low status, those with adequate-to-high status might be affected adversely and should not take selenum supplements.

TL;DR: This review describes the current experimental tools to study endocytosis of nanomedicines and provides specific examples from recent literature and the authors' own work on endocyTosis of Nanomedicine.
