Product Name

Name:a>Pegylated ultrafine Fe3O4 nanoparticles(High-temperature Pyrolysis Method)

Product Overview

PEGylated ultra-small Fe3O4 nanoparticles (high-temperature pyrolysis method) are poor nanomaterials synthesized by high-temperature pyrolysis method. The diameter of these nanoparticles is usually less than 10 nanometers (<10 nm), as observed by TEM. Size is generally in the range of 5-10 nm

Technical Parameter

Composition: Pegylated ultrafine Fe3O4 nanoparticles,ultra-pure water

Diameter:<10 nm

Modified group: Methxy, hydroxyl, carboxyl, amino are optional

Note: This Fe3O4 nanoparticle is too small to be attracted to the magnet.

Product Features

Ultra-small size: The size of this type of nanoparticles is usually in the range of 5-10 nm. The ultra-small size helps to improve its diffusion capacity and cellular uptake efficiency in living organisms. PEGylation surface modification: Modifying the surface of nanoparticles with polyethylene glycol (PEG) increases their stability and biocompatibility while reducing non-specific interactions with biomolecules. High-temperature pyrolysis synthesis: One-step synthesis using high-temperature pyrolysis. This method can obtain single-crystal iron nanoparticles with uniform size and good crystallinity. Superparamagnetism: These nanoparticles exhibit superparamagnetic properties with high saturation magnetization, making them suitable for magnetic resonance imaging (MRI) and magnetic hyperthermia therapy (MHT). High biocompatibility: PEGylation improves the compatibility of nanoparticles with biological systems and reduces immune response and toxicity. Long circulation time: PEG modification helps extend the residence time of nanoparticles in the blood circulation and increases their ability to accumulate in diseased sites.

Application Fields

Magnetic resonance imaging (MRI) contrast agent: Due to its superparamagnetism, Fe3O4 nanoparticles can be used as a T2 contrast agent for MRI, reducing the relaxation time of surrounding protons and improving the clarity and accuracy of imaging. Surface modification can improve the biocompatibility and tumor targeting performance of Fe3O4 nanoparticles, ultimately improving MRI imaging signals and therapeutic effects. Magnetic hyperthermia therapy (MHT): Fe3O4 nanoparticles can generate local high temperatures under the action of an external alternating magnetic field and are used for magnetic hyperthermia therapy to treat tumors. Through surface modification, Fe3O4 nanoparticles can enhance their accumulation inside tumors, thereby improving the effect of magnetothermal therapy. Drug delivery system: Fe3O4 nanoparticles can be used as drug carriers, enriched in tumor tissues through the EPR effect, and improve the targeted transport efficiency of drugs. For example, Fe3O4@void@ZnO-DOX nanoparticles designed using a template-assisted method are used for magnetic targeted delivery of drugs to treat tumors. Multimodal imaging and tumor collaborative therapy: Fe3O4 nanoparticles and their derived composite nanomaterials have attracted widespread attention in multimodal imaging and tumor collaborative therapy. Fe3O4 nanoparticles of different sizes can be obtained through different preparation methods, and modification on their surface can improve biocompatibility and tumor targeting performance.

Great for dry skin
Size: 20.3 Fl Oz (Pack of 3)
I use this lotion to help with my dry skin and it is the only one that really helps. I live that it doesn't smell funky. it's lightweight on my skin and not too thick . it is strong enough to relieve my skin and gives my skin a nice glow . With 3 in the package it provides quality in quantity at a good price. The bottles come wrapped tight so there wasn't any leakage in the bottles. The bottles are big enough to provide enough to last

Quality. Price
Size: 20.3 Fl Oz (Pack of 3)
I have bought this lotion alot I the past. But this is the best price I have got. It is the main reason for my purchase other than I liked the lotion. If you have never tried this lotion then dont hesitate, its pretty good stuff. I recently I have became more conscious of the ingrediants on lotions so I switched. But I wouldn't hesitate to use this. Save some money and time and buy it here if you are already a regular user. And if you looking to try it out I wouldn't hesitate unless you are ingrediants conscious. It definitely moisturizes the skin untill your next shower. Feels good. Not greasy. Apply for any sort of dry skin. And it smells good if that's one of your requirements.

Love This Product on My Skin. Buy the 3-Pack for Epic Savings
Size: 20.3 Fl Oz (Pack of 3)
I always recommend checking Amazon for three-packs, family packs, or value bundles of products you use all the time, because that’s usually where you start seeing real savings. Everyday household products can get expensive when you’re constantly buying single bottles at grocery stores, so finding a good bulk deal really does make a difference over time. That’s especially true with a quality product like Vaseline Cocoa Radiant Body Lotion. It’s a great moisturizer, works well for sensitive skin like mine, and leaves your skin feeling soft without feeling overly greasy. The scent is phenomenal too, which makes it something you actually enjoy using regularly instead of just treating like another basic lotion. What I also like about this three-pack is that the bottles are lightweight and easy to handle. They’re convenient enough to take on an overnight trip or keep stored neatly in the bathroom without taking up too much room. And because you’re getting multiple bottles at once, you don’t feel like you’re constantly running back to the store every couple of weeks. If you actually compare prices and pay attention to sales, you’ll notice these bundles on Amazon can end up being significantly cheaper than buying individual bottles locally at a grocery or department store. The value is definitely there with the three-count package, especially for a name-brand product that consistently works well. Highly recommended if this is already a product you use regularly.

Highly hydrating and non-greasy
Size: 20.3 Fl Oz (Pack of 3)
I’ve been using Vaseline Intensive Care Cocoa Radiant Body Lotion for quite some time, and it’s easily one of the best lotions for daily use. It absorbs quickly into the skin without leaving that heavy, greasy residue behind, which is a huge plus when I’m getting ready in the morning. The cocoa butter scent is subtle and pleasant—not overpowering—and it does a fantastic job of keeping skin hydrated throughout the day, even in drier climates. Having the 3-count pack is super convenient, as it ensures I’m stocked up for a while. It’s a reliable, high-quality moisturizer that consistently delivers on its promise of a healthy, radiant glow.
