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

Perfect for my needs
I don’t have many towel racks in my bathrooms and they’re hard for me to reach because I’m disabled. I bought a couple of small over the door racks, but they’re too small for hand towels. I didn’t have high hopes for this adjustable rack, I thought it would uncouple and fall from the door. I’m pleased to say I was wrong. There appears to be a stopper keeping both sides in place. I like that it has 2 bars, I easily put my face towel on one and my hand towel on the other. If I have a complaint, I wish the whole unit was another inch longer.

Perfect fit & couldn't be easier to install
Even though I measured I wasn't sure about the size or how the extending would work. It works very well and seems to stay securely in place fully extended. The felt pads are a nice touch and make sure it doesn't move around as you place & remove towels. It looks great. As far as people who've commented that the metal's a bit thin; well is a bit on the thin side but for kitchen towels I don't see that being an issue. I'm very happy with this purchase.

Pure Perfection!
Color: Black
Love this addition to my sink! It holds dishwashing liquid, hand soap pump, spounges, scrapers, and dish rag with room to spare. Any liquid will drain from the multi-directional spout right into your sink. The materials are all metal, no flimsy plastic dish rag holder.

Well made and sturdy.
Color: Black
Very sturdy and well made. Doesn't slide around every time you touch the soap dispensers like our last one.
