I. [Product Description]
    PEG-coated Fe₃O₄ nanoparticles (30 nm) are a type of surface-functionalized magnetic nanomaterial. The modification with polyethylene glycol (PEG) significantly enhances their dispersibility and colloidal stability. This product can be used as an organic intermediate or a catalyst carrier, showing unique advantages in fields such as magnetic separation and targeted delivery.

II. [Product Details]
    【Appearance】 Black magnetic suspension with good aqueous dispersibility, particle size 30 ± 5 nm
    【Stability】 Avoid strong acid/alkali environments. Ultrasonic dispersion is required after magnetic precipitation.
    【Solvent】 Water, PBS buffer, ethanol (requires pretreatment)
    【Molecular Weight】 PEG segments: 2000, 3400, 5000 (supports carboxyl/amino terminal modification)
    【Storage Conditions】 Store at 4°C in the dark. Freezing is strictly prohibited.
    ▪ Note: ▶ After opening, seal with nitrogen. It is recommended to add 0.02% NaN₃ for long-term storage to inhibit bacteria!
