Product Name

Name:a>OA Coated Fe3O4 Nanoparticles


Product Overview

 

High temperature pyrolysis method was used to prepare oleic acid modified iron oxide nanoparticles, and oleic acid was added as a surfactant to a solution containing iron precursor. Oleic acid not only helps to control the growth of nanoparticles, but also forms a stable coating on the surface of the particles.

Heat the solution containing iron precursor and oleic acid to a high temperature, usually around 300 ° C, to promote the thermal decomposition of the iron precursor. At high temperatures, iron precursors decompose to produce iron atoms, which aggregate to form magnetic nanoparticles.

During the pyrolysis process, iron nanoparticles react with oxygen in the air to form Fe3O4.


Technical Parameter

Concentration: ~4 mg/mL

Zeta potential: -42.7mV

Saturation magnetization: ~60 em2/g Fe

Solubility: oil soluble, can be dispersed in cyclohexane, chloroform, tetrahydrofuran and other solvents


Product Features

 

Oil solubility: These nanoparticles have oil solubility and can be dispersed in organic solvents such as cyclohexane, chloroform, tetrahydrofuran, etc.

High temperature pyrolysis method preparation: Oleic acid modified Fe3O4 nanoparticles prepared by high temperature pyrolysis method have stronger magnetic properties and more uniform size.

Stability: The modification of oleic acid enhances the stability of nanoparticles, helping to maintain their performance in different applications.

Diverse specifications: Provide nanoparticles of different sizes to meet the needs of different applications.


Application Fields

 

Magnetic resonance imaging (MRI) contrast agents: Due to their superparamagnetism, these nanoparticles can serve as contrast agents for MRI, enhancing imaging contrast and helping to observe tissues and organs more clearly.

Biosensing and Detection: In biosensors, Fe3O4 nanoparticles can serve as signal converters or enhancers to improve the sensitivity and selectivity of detection.

Doped oil in water nanoemulsion: Fe3O4 nanoparticles modified with oleic acid can be dispersed in organic solvents such as cyclohexane, chloroform, and tetrahydrofuran for doping oil in water nanoemulsion.

Great for aggressive chewers!
Size: Jumbo, Style: Peanut Butter
I have a very very aggressive chewer. She is a Rottweiler/Pitbull mix. Most toys she completely destroys within 2 days, sometimes 2 hours. I must praise this toy as she has had it for over 5 months and has not destroyed it! She loves chewing the ends and carries in her mouth squeaking it as she goes. I have 4 pups and they all take turns chewing when they can. I will be buying more Playology dog toys in the future. Thank you for making such a great toy!!

They are her favorites
Size: Medium (VALUE 2-Pack), Style: Beef, Size: Medium (VALUE 2-Pack), Style: Beef
We’ve had many dogs, many very destructive ones and wish I had these years ago. The hard toys get sharp edges, this toy is the best and yes is far better than the other red ones. My bulldog wants tug of war for 30 min to an hour every night. We’ve gotten tennis elbow, tendinitis, and pulled muscles holding onto this thing. She has tons of toys but 9pm and this is only option for her. We don’t get a choice. Easy to hold, well for a few min until your hand gets tired. First you one was about 3 years ago and she’s only on her third one. They last forever, easy to clean, and aren’t sharp edges. Seriously, better than any toy sold anywhere. My phone has hundred of pictures of Pickle holding this. She’s doing it right now. If you have a strong destructive dog that takes pride in destroying toys, ruin their confidence and get them this one.

Perfect Toy for Large Dogs
Size: Medium, Style: Cheddar Cheese
I don’t normally leave reviews, but this toy is stellar and is a new favorite for my dog! She is a large dog (70lbs cattle dog lab mix) and I accidentally bought a medium, but it actually is a great size for her! So far this stands up to her chewing, but I may need to update in a few weeks to speak for durability but it really does feel solid. Most toys don’t last an afternoon once she starts chewing, so this has already won in that regard. The shape is perfect as well. She can gnaw at it, squeak, play fetch, play tug. It bounces when she throws it around herself. The fact it smells like stinky cheese is just an added bonus for her. All around, a very well designed dog toy!

Boxer Baby’s Favorite
Size: Jumbo, Style: Beef
This toy is my sweet girl’s absolute favorite. It was the first thing we gave her when we brought her home, and she has been obsessed with it since. She brings it from room to room, inside and outside. I would highly recommend this toy, however, we have gone through six in one year. They’re not very durable, especially with our boxer mix, who is a very heavy chewer. I’ve gotten the red and the blue, and she will only take red, which is fine with me because the blue STINKS. The red stinks too, but less so. The squeak is very loud, but she genuinely loves it so much that it’s hard to be annoyed by it. I’d say give the toy a try, you may be unintentionally giving them their favorite thing ever lol.

Design Hazard
Size: Medium, Style: Bacon, Size: Medium, Style: Bacon
I have one of these in a larger version I picked up at the petstore. This one I do not recommend. There is a whole in the center where the pet bites down and my doggies' teeth kept getting stuck in it. If you've ever had a toy get stuck in your pups mouth, you've seen how thet go nuts trying to get it out.
