Silicon dioxide coated selenium nanoparticles

Product Name Silicon dioxide coated selenium nanoparticles Product Overview Selenium nanoparticles have potential for anti-cancer and antioxidant effects, but they have two natural shortcomings: they are prone to aggregation in liquids and lack active sites on the surface for subsequent functional modifications. By constructing a silica shell on the surface of selenium nanoparticles, not only can selenium particles be physically isolated and prevented from aggregating, but also a reliable chemical platform is provided for the functionalization of the shell, significantly improving its stability and biocompatibility in physiological environments. Technical Parameter Concentration:1 mg/mL Solvent:Water Diameter:20-30 nm(TEM) thickness:10-30 nm Stabilizer:CTAB Diameter:Red solution Product Features 1) Chemical stability: The silica shell can effectively prevent nanoparticle aggregation, ensuring its long-term stability during in vivo circulation and storage. 2) Good biocompatibility: Through the confinement and sustained release effects of the silica shell, the release rate of selenium is effectively controlled, while maintaining or enhancing its therapeutic effect, significantly reducing its potential toxicity to normal cells and broadening the therapeutic window. Application Fields 1) Nano fertilizer: Using silica sol as a carrier to disperse selenium nanoparticles, as a new type of nano fertilizer, foliar spraying can significantly promote crop growth, increase the selenium content of crops, and produce selenium rich agricultural products. 2) Crop protection: It can effectively inhibit the absorption of harmful heavy metals such as arsenic and cadmium in the soil by crops, playing a role in protecting crop safety.
