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.

Exactly what I wanted!
It is really exactly what I was looking for. I've been living with my jewelry in ziplock bags since we moved over here and everything fits perfect. I saw some reviews that claimed it was unstable but I tested it and it seems sturdy though I'm not hanging heavy pieces. It is a nice size and I love the little ring basket. It also feels pretty decent quality too. Glad I got the black one as I'm not sure where I have it that the copper/bronze would look right. I think it is elegant, practical and I wish I could post a photo with my pieces on it to show that it really holds things beautifully.

Looks great by my bed!
Even my boyfriend keeps commenting how much he likes it. It's a usable piece of art! I will comment that the earring holes can be a little tricky since the leaves are turned all different ways. You have to be strategic with how you line up your long/dangle-y earrings with your studs so everybody fits and can be seen. A little tricky. But not a deal breaker - especially when it's so easy on the eye. The other slight negative is that this really isn't the best necklace holder. I would have thought, "No problem!" But it's a bit awkward. Especially if you actually intend to see all your earrings. You'll end up hanging most of your necklaces from the top most branch - but they slide down into the crevice to stay. Then you've got a lot of overlapping. And trickiness to retrieve the exact necklace you want with ease. However, this is still a fabulous earring tree. I can't say enough good things about it. Love the little basket for miscellaneous. Hair bands, lip gloss, etc.

Beautiful jewelry display
Color: Bronze-Tone
A few rough edges, but all in all well made and attractive. Holds lots of earrings and I can drape my necklaces on the tree. There's a nice bowl for bracelets and a nice tray that forms the base.

Gorgeous
Color: Bronze-Tone
It really is pretty to look at. To be honest arranging the earring on the tree is a bit of a pain, because the leaves tilt in different directions, and you have to play with it a bit to get the earrings to hang the way you would like them, but once you figure it out, they look very nice. I just adore it because it looks so pretty. I use the basket on the side for rings and watches, and the little plate in the base for a few miscellaneous pieces like necklaces or bracelets for balance and because they look nice. You'll love it.

gorgeous, and worth the purchase.
Color: Bronze
I wasn't sure about purchasing the jewelry stand at first (I had my doubts), but those doubts quickly disappeared upon the arrival/unpackaging of the jewelry stand. SHIPPING/PACKAGING It was nicely packaged, and not bent or damaged when I recieved it. The stand was a little wobbly (due to careless measuring of the copper balls, the fault of the manufacturer) THE PRODUCT The pictures are not how it is. Remember that. I thought the tree would be more three dimensional, you know- like a real tree. It wasn't, though. It was like someone took a 2D copper tree and made it stand up. It's still pretty, though, and holds a lot of jewelry. PRICE-WISE If you're looking at the price and it says $45 or more, don't buy it. I waited a month for the price to go down (I'm just a cheapskate) and it did. It went from $45 or so, down to $25 or so. So, unless its life or death, be patient and buy it when the price is right. OVERALL? In general, I was pleased with the product. It wasn't my dream jewelry stand, but it was worth my money and the wait.
