Product Overview

 

The core material of carboxylated dextranModified ferric oxide nanoparticles is ferric oxide, which has superparamagnetic properties and is suitable for magnetic field response applications. The surface is covered with carboxylated dextran, a modification that increases the water solubility and biocompatibility of the nanoparticles while providing carboxyl functional groups that facilitate further chemical modification and coupling of biomolecules.


 

Technical Parameter

Particle: 5-20nm(TEM)

concentration:~1 mg/mL

 

Product Features

 

Superparamagnetism: Fe3O4 nanoparticles are superparamagnetic and can be rapidly magnetized and demagnetized under an external magnetic field. They are suitable for magnetic resonance imaging and magnetic hyperthermia. Carboxyl Functionalization: Surface carboxylation provides reactive chemical groups that facilitate covalent binding to drugs, biomolecules, or targeting ligands. Biocompatibility: Modification of carboxylated dextran improves the compatibility of nanoparticles with biological systems and reduces potential toxicity to normal cells. Stability: Modification of carboxylated dextran enhances the stability of nanoparticles in vivo and reduces the risk of aggregation and precipitation.

 

Application Fields

 

Magnetic Resonance Imaging (MRI): These nanoparticles can be used as MRI contrast agents to enhance imaging signals. Modification of carboxylated dextran improves its biocompatibility and stability in vivo, thereby improving imaging quality. Magnetic Hyperthermia (MHT): Fe3O4 nanoparticles can produce a thermal effect under the action of an external alternating magnetic field and can be used in magnetic hyperthermia therapy, especially in cancer treatment, to selectively kill cancer cells. Medication Delivery: Carboxylated dextran-modified ferric oxide nanoparticles can be used as drug carriers for drug delivery through their magnetism and the hydrophilicity of the carboxyl group. These nanoparticles can be combined with proteins or other biomolecules through covalent bonds to achieve targeted drug delivery. Biomolecular conjugation: The surface carboxyl functional groups of these nanoparticles can be coupled with biomolecules such as proteins, antibodies, and enzymes for biosensing and diagnosis.Nanoprobe construction: Carboxylated dextran-modified iron ferric oxide nanoparticles can be used to construct nanoprobes for biological detection and analysis.

My Golden Retriever’s favorite
We’ve owned lots of toys and balls. This specific version (in blue) has been her absolute favorite. She’s about 72lbs and chews on this thing regularly with no visible damage. We actually own about 6 of them because they have a tendency to go missing underneath furniture and in the yard. We have two of the orange colored ones but she doesn’t like those nearly as much which I assume is because the blue is easier to see in the grass. Other than that…They bounce really well and also whistle a little when you throw them hard enough. I hope they never stop making these.

doesn't whistle as loud as other chuckit balls I've seen, but a good ball.
makes some noise, but I've seen (and played with) others at the dog park that whistle much louder than the 1 I got. all Chuckit balls... so, just this one I'm betting. but it flys good and the dog loves to chase it. he chews it a fair bit as well and the ball has not taken much damage from him (lab mix) or others that have had a go at it. I'll likely buy another at some point ... just wish it was a little louder when flying.

Blue ball, my dog likes blue.
Just a ball right? Evidently not! My dog won’t chase an orange chuck it ball or the glow in the dark ball- only the blue one 🤷🏼‍♀️
