Product Name

DMSA coated Fe3O4 nanoparticles (High-temperature Pyrolysis Method)


Product Overview

Carboxylated Fe3O4 nanoparticles (high-temperature pyrolysis method) are obtained by modifying DMSA with XFJ67 to obtain carboxyl groups, converting oil soluble nanoparticles into water-soluble nanoparticles, which are more suitable for applications in the biological field.


Technical Parameter

 

Form: Brown black clear water colloid

Fe concentration: about 4 mg/mL

Particle diameter:~5, 10, 20, 30, 50 nm (TEM) optional

Note: There are slight fluctuations in diameter and concentration between batches.

Note: Magnetic separation columns are required to achieve magnetic separation below 10nm

20nm can be separated by long-term magnetic attraction (the effect is not good, please use a magnetic separation column for complete separation)

Directly magnetically attracted above 30nm

50nm is prone to precipitation and requires ultrasonic treatment before use.


Product Features

High surface negative charge: DMSA molecules form stable covalent bonds with the surface of Fe3O4 nanoparticles through their thiol groups, forming a thick molecular coating layer that imparts high surface negative charge to the nanoparticles.

Hydrophilicity: Fe3O4 nanoparticles modified with DMSA have good hydrophilicity and can maintain stability over a wide pH range.

Stability and dispersibility: DMSA modified Fe3O4 nanoparticles exhibit good dispersibility and stability, making them suitable for biomedical applications.

Can be used for biomolecule coupling: Due to the carboxyl groups on the surface, DMSA modified Fe3O4 nanoparticles can be used for biomolecule coupling and fixation, constructing nanoprobes.


Application Fields

Biomedical applications: Fe3O4 nanoparticles modified with DMSA can serve as drug carriers for targeted drug delivery and contrast enhancement in magnetic resonance imaging (MRI) due to their excellent biocompatibility and stability.

Magnetic hyperthermia (MHT): Under the action of an external alternating magnetic field, these nanoparticles can convert magnetic energy into thermal energy, which is used for magnetic hyperthermia treatment of tumors.

Gene therapy: DMSA modified Fe3O4 nanoparticles can be used as gene carriers for gene transfection and gene therapy.

Materials Science: In composite materials, Fe3O4 nanoparticles modified with DMSA can enhance the magnetic properties of the material, which can be used for the development of smart materials and sensors.

Biomolecular coupling: The carboxyl groups on the surface of Fe3O4 nanoparticles modified with DMSA can be used for the coupling of biomolecules, constructing nanoprobes for biological detection and analysis

My Go-To Cotton Rounds — Don’t Fall Apart & No Fuzz
Color: Ultra Soft, Size: 100 Count (Pack of 3)
These are my favorite cotton rounds, and I’ve tried everything from dollar store versions to higher-end “eco” brands. I keep coming back to these. They stay intact and do not separate, even when fully saturated. I use them for micellar water, toner, and nail polish remover, and they hold up well with all three. No fuzz left behind, no pilling, and no pieces sticking to my face. The thickness is just right — not too thin, not overly bulky. They’re soft but durable. I also like that one side has a slight texture. It’s not harsh or labeled as “exfoliating,” but it does have a subtle grip that helps with product application without irritating the skin barrier. Compared to cheaper brands that fall apart and more expensive ones that don’t perform any better, these strike the perfect balance of quality and value. Definitely a repeat purchase for me. TL;DR: Soft, durable, no fuzz, and don’t fall apart. Perfect thickness for toner, micellar water, and nail polish remover. My consistent repurchase.

Good Quality Cotton Rounds
Color: Ultra Soft, Size: 100 Count (Pack of 3)
I recently purchased these cotton rounds, and I couldn’t be happier with them! They are soft, durable, and incredibly gentle, making them perfect for my daily skin care routine. They don’t leave behind any lint, and they hold up well when applying toner or removing makeup. One unexpected bonus is how great they are for my cat with skin allergies. I use the rounds to gently clean around sensitive areas, and the soft texture ensures I don’t irritate her skin. Another huge plus is the value. The set comes with a generous amount of rounds for the price, which makes it both practical and economical. For anyone looking for versatile, skin-friendly cotton rounds that work for both personal care and gentle pet care, this set is an excellent buy!

Just Love These Little Pads
Color: Ultra Soft, Size: 100 Count (Pack of 6)
I use these everyday, at least twice a day and they are perfect for applying toner, etc. The little pads absorb liquid well so you don't use too much of something, or the liquid rolls off onto the counter, they fit perfectly on the ends of my fingers, they don't leave lint on my skin, and are thin enough to be used easily and well. They do not scratch my skin, they are not rough, and they don't stick to me. I use them only once and throw away. The price of them is reasonable and a box of them is always sitting in pantry. I've used them to applying antiseptic to cuts,, giving to my husband for dotting a razor cut, and as a protector inside a jewelry pouch. I just love these little pads.

Great cotton rounds and a great deal
Color: Ultra Soft, Size: 100 Count (Pack of 3)
What a great deal on cotton rounds. I use this daily to tone my skin and to remove my makeup. The cotton doesn’t break up on me and it doesn’t irritate my skin. Definitely a great choice for your cotton rounds

Great Quality Cotton Rounds at a Good Price
Color: Ultra Soft, Size: 100 Count (Pack of 3)
I use these cotton rounds regularly with micellar water to remove my makeup, and they work really well. They’re soft on the skin and effective without feeling rough or irritating. The amount you get for the price is a big plus. The rounds hold product well and don’t fall apart while using them, even when fully saturated. They make makeup removal quick and easy as part of my everyday routine. There isn’t much to improve—they do exactly what they’re meant to do and feel reliable for daily use. Overall, this is a solid product at a good price, especially if you go through cotton rounds often. I’d definitely repurchase.
