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.

Durability and lasting period of toy.
Color: Green
I got this toy for our bulldog. He had a hole in it, which will only progress, within minutes. I took it away until I could find out if there is any kind of warranty. The information says this toy is not for aggressive chewers, yet right in the description and the photo of the toy (that way I knew I was looking at the correct toy), it says for the "aggressive chewer". I am disappointed that even though it isn't how they described, it only lasted minutes before there was damage. Not sure if I would buy another product.

Excellent toy for active dogs! Five ⭐️
Color: Green
⭐⭐⭐⭐⭐ Excellent Toy for Active Dogs! This is my second time purchasing this toy, and it absolutely deserves five stars. My youngest dog, Captain, is a very active 3-year-old with more energy than I can keep up with. He loves being able to sink his teeth into this squeaky toy, and it helps keep him mentally stimulated and entertained. What I love most is that he also shares it with his older brother, Kane. They use it for tug-of-war, which helps burn off some of Captain’s endless energy and keeps both dogs engaged. It does a great job reducing boredom, especially for highly active dogs. The first one lasted several months before needing replacement, which is impressive considering how much it was used. If you have energetic dogs that need something durable and fun, I highly recommend this toy!

Perfect Pup Pal
Color: Green
I purchased this dog toy as a birthday gift for a friend's dog, and it exceeded all expectations. Knowing she is particular about toys and easily frightened by many, I spent quite some time choosing the perfect one. From the moment she took it out of the box, she adored it. Everyone at her birthday party was amazed. Watching her happily play with her new toy, which we've come to call Allie, is truly heartwarming. The quality is outstanding. It is well made, safe, and nearly indestructible, yet gentle enough on her mouth. I will definitely be buying more from this store.

Awesome toy!! Labrador Retriever approved
Color: Green
I bought this for my nephew’s Labrador retriever. He pulled it out of the bag and immediately started taking it around for everyone to throw around and play tug a war with. He played with it for hours outside (it definitely needed washing lol). Its durable showed no signs of tearing. I would definitely recommend this!!
