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.

"Durable Fun: Pweituoet Heavy Duty Squeaky Dog Balls for Aggressive Chewers"
Size: 4.5"
Product Review: The Pweituoet 4.5” Heavy Duty Squeaky Dog Balls have been a hit with my dog, proving to be both durable and entertaining. Durability: These dog balls are impressively tough. My dog is an aggressive chewer, and most toys don’t last long, but these balls have held up exceptionally well. The heavy-duty material and spiked design are perfect for dogs who love to chew, providing both durability and safety. Entertainment: The built-in squeaker adds an extra layer of fun. It captures my dog’s attention immediately, and the squeak keeps him engaged for longer play sessions. The spikes also make the ball easy for him to grip and carry around. Size: The 4.5” size is ideal for medium to large dogs. It’s large enough to avoid being a choking hazard but still easy for my dog to pick up and play with. The size and weight are just right for games of fetch, too. Value: Given the durability and how much my dog enjoys these balls, they offer great value for the price. They’ve lasted much longer than other toys we’ve tried, making them a worthwhile investment for any dog owner with a tough chewer. Overall Verdict: The Pweituoet Heavy Duty Squeaky Dog Balls are an excellent choice for medium to large dogs, especially those who are aggressive chewers. They’re durable, fun, and well-sized, making them a great addition to your dog’s toy collection. Highly recommended!

Actually stands up to use
Size: 4.5", Size: 4.5"
I have a pitbull who is a toy destroyer. All those toys, even the ones that say tough enough for destroyers, never hold up. THESE BALLS ARE AWESOME! I bought the 2 pack of the 4.5 inch balls and they lasted a year. I literally am writing this review after ordering a new set. These are well worth the money and Ghost (my dog) loves them. Hes a 103lbs pitbull and his life mission is cuddles and destroying his toys... and these lasting a year of everyday use is friggin awesome. Both toys failed in the same way eventually. They gave out in a circle around the "squeker".

She chewed it up in less than 10 minutes. This is not for heavy chewers but dogs that like to actually play with their toys it would be great!!! I gave it a 3 because it worked for my other dog who likes to play🤘

loud but in a good way
Size: 4.5"
Love these crazy loud squeeky balls. I bought two a bit too big but the dogs still love them. Yes, they will drive you insane but the dogs love them so much it's worth it watching the pups enjoy the balls. They are strong and safe as long as they aren't too small for your dogs mouth.

Great for aggressive chewers - Great for clean teeth
I never thought these would stand up to my 60lb pittie puppy's chewing. But they are far and away her favorite toy and are holding up beautifully. One squeaker insert bit the dust -- which is not bad since it gives us one silent one. But otherwise they are holding up superbly to her powerful jaws. We have tried a lot of toys. So far, all the "for aggressive chewers" toys have been torn apart within days if we are lucky -- usually it's minutes. But these balls show little-to-no sign of wear. The squeakers are very loud which she loves can get a bit tiresome. So, as I mentioned, having one silent one is a great option. And she really likes the texture. She loves them so much, we bought a second set and will probably buy a third to have in reserve. (We are realistic and don't expect them to last forever.) All I have to say is "where's spiky ball" and she instantly stops what she is doing and goes on the hunt. A great buy!! (NOTE: It's been almost three months and one is just beginning to show some damage. Given that she plays with them non-stop, they've showed amazing durability. And everyone comments on how clean and beautiful her teeth are. I don't brush them or give her dental treats. So it has to be these balls!!)
