Product Name

Name: Magnetic mesoporous silica nanoparticles

Product Overview

 

Magnetic mesoporous silica nanoparticles are a multifunctional nanocomposite material that coats magnetic nanoparticles (usually superparamagnetic Fe3O4) in mesoporous silica (SiO2). This material combines the magnetic properties of magnetic nanoparticles with the high specific surface area, uniform pore structure and good chemical stability of mesoporous silica.


Technical Parameter

 

 Appearance : Yellow brown dispersion

Ingredient:Fe3O4、SiO2

Diameter:0-60 nm (TEM)

Core Diameter:-10nm

 

Note: The product can be attracted by the magnet, the adsorption time is about 20min, and the product solvent can be replaced with water or PBS. Replacement conditions were centrifuged at 10,000 r. p. m. for 20min.

 

Product Features

 

Preserved magnetic response: The presence of magnetic nanoparticles allows the material to be manipulated and separated by external magnetic fields, facilitating applications in biomedicine and environmental engineering.

Mesoporous silica matrix: Provides a stable platform and high specific surface area. The pore size is generally between 2-50 nanometers, which is conducive to the adsorption, diffusion and catalytic reaction of molecules.

High specific surface area: The mesoporous structure increases the specific surface area of the material, which helps to improve the catalytic efficiency and the adsorption capacity of substances.

Chemical stability and biocompatibility: The silica matrix has good chemical stability and biocompatibility, making it suitable for applications in the biomedical field.

Versatility: Different functional groups can be introduced through surface modification or post-treatment to achieve adsorption, catalysis or targeted release of specific molecules.


Application Fields

 

Drug delivery system: MMSNs can be used as efficient drug carriers for targeted drug delivery and controlled release, improving drug efficacy and reducing side effects. They can be loaded with multiple drugs, including hydrophilic and hydrophobic drugs, to achieve synergistic treatment.

Magnetic resonance imaging (MRI) contrast agent: Due to the superparamagnetism of magnetic nanoparticles, MMSNs can be used as MRI contrast agents to enhance imaging signals and contribute to the early diagnosis of diseases.

Magnetic hyperthermia: In an alternating magnetic field, magnetic nanoparticles can generate heat and are used to treat cancer, that is, magnetic hyperthermia. MMSNs can combine magnetocaloric effects with drug delivery to improve therapeutic effects.

Catalytic applications: Due to the high specific surface area and pore structure of magnetic mesoporous silica nanoparticles, they can serve as catalysts or catalyst supports for various chemical reactions.

Didn't last unfortunately
Size: Large
Purchased for my pup for Xmas. It's very cute, I love squirrels. Already pulled out the strings. He is a persistent chewer. Unfortunately had to toss.

Super Sturdy with hours of fun.
Color: Wild Duck, Hare, Squirrel & Alligator, Size: Small
I got the small ones that you cannot put a water bottle in. These toys have held up way better than expected. I am dog sitting a very rough with toys dog named Chunk. He tears up ever. Single. Toy my dog (Ted) has. I bought new ones just for chunk. These appealed to me with the no stuffing, They were cheaper, and have a squeaker. Everything chunk needed. They arrived on time and I thought I wasted my money. They were super soft, like too soft. They felt flimsy and weak. Like 5 minutes with chunk and they be dead. 2 hours with my dog and they would have a rip. So far 2 of them (I set two out) have lasted the whole weekend. The bunny looks very rough and disgusting, but no rips, the squeakers still work, and no random fluff everywhere. I am going to wash the bunny once chunk leaves. My very careful doggo Ted loves them too. He throws them up in the air and catches them, plays tug of war with them, and no rips. They are super sturdy. He can’t wait until Chunk leaves (chunk is 2 and Ted is 12-13) so he can play with them.

Loved it
Color: Brown/Wild Duck, Size: Large, Color: Brown/Wild Duck, Size: Large
He loved it so much, he destroyed it so we ordered another. I didn't realize that you can stick an empty water bottle inside. Again, the first one didn't last long, but he enjoyed it

Very fun interactive toy
Color: Brown/Wild Duck, Size: Medium
This toy is very versatile. There's no stuffing yet it's very soft so it can be used as a tug toy. It also makes for a fun fetch toy because it has a cavity to put a water bottle. It gives your dog something that crinkles and can be pierced when bitten and easily replaced with another empty bottle whenever necessary. That is what really makes this toy the standout of all the ones offered by Best Pet imo. I don't expect this to last forever but once my pup gets bigger we'll probably get the large size for her because there's not too many all in one fetch and tug toys at an affordable price.
