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.

Excellent Quality and Good Value
Size: 100 Count (Pack of 1)
While these really don't cost any or much less than the grocery store pads, I do find that they have good cotton content, are exceedingly soft, remove makeup often with one swipe, shed very little if at all, and are quite versatile. I've bought them three times and plan to keep it up.

Last a while
Size: 100 Count (Pack of 6)
Work well and have lasted me more than six months. They do get pulled apart easily so sometimes wiping your face leaves the cotton fuzzies

Good Buy
Size: 100 Count (Pack of 1)
These seem to be pretty good especially for the price. I use mascara that’s pretty tough to remove, these cotton rounds help along with makeup remover without coming apart. They are soft and are lint free. They also absorb very well.

Soft, Durable, and So Much Better Than Cotton Balls
Size: 100 Count (Pack of 1)
These cotton pads have been such a simple but huge upgrade to my routine. For years I used regular cotton balls or even toilet paper for skincare and makeup removal, so I wasn’t expecting these to make that much of a difference. After seeing them on Amazon, I decided to give them a try, and now I don’t want to go back. They are incredibly soft and gentle on my skin, especially around my eyes. I mainly use them for applying toner and removing eye makeup, and they work perfectly for both. They don’t fall apart, leave lint behind, or soak up tons of product like regular cotton balls do. The size is perfect too — large enough to be useful without wasting product. One thing that really surprised me is how well they work for removing nail polish. I can usually remove polish from all ten nails with just one cotton pad, which definitely helps them last longer. Overall, these feel much more high quality than standard cotton balls, and they’ve made my skincare routine easier and less messy.

Great for Skin
Size: 100 Count (Pack of 6)
These Amazon Basics Hypoallergenic 100% Cotton Rounds for Makeup Remover and Skincare are honestly a great find. They’re super soft—so they feel nice on your skin—and they’re tough enough not to fall apart when you use them. Plus, you get a lot for a really good price. If you need something simple that just works for cleaning your face or taking off makeup, these cotton rounds do the job without any fuss.
