Product Overview

 

Carboxylated magnetic microspheres are a type of magnetic microsphere with abundant carboxyl functional groups on the surface, usually composed of superparamagnetic materials (such as Fe3O4) and polymer materials.

Zeta Potential:-35 mV:μm:/span>

 

Product Features

 

Superparamagnetism: Carboxylated magnetic microspheres are usually made of superparamagnetic materials (such as Fe3O4), which can quickly magnetize and exhibit magnetism under an external magnetic field. When the magnetic field is removed, they can quickly lose their magnetism, making them easy to operate and separate in biomedical applications.

High specific surface area: Due to their nanoscale or micrometer particle size, carboxylated magnetic microspheres have a high specific surface area, which allows them to provide more active sites, making them suitable for immobilization and catalytic reactions of biomolecules.

Surface carboxyl functional groups: The surface of carboxylated magnetic microspheres is rich in carboxyl functional groups, which can covalently bind with biomolecules (such as antibodies, enzymes, proteins, etc.) through chemical crosslinking agents, enhancing their functionality in biomedical applications.

Good biocompatibility: Carboxylated magnetic microspheres are typically made of biocompatible materials that can be safely used in vivo, reducing immune reactions and toxicity.


Application Fields

 

Immunochromatographic detection: Carboxylated magnetic microspheres can modify the surface of antibodies and be used to construct immunochromatographic test strips for rapid and sensitive detection.

Fixation of biomolecules: Carboxylated magnetic microspheres can be used as carriers to immobilize enzymes and other biomolecules for biochemical reactions and biological separation processes.

Cell separation and purification: Due to the superparamagnetic nature of carboxylated magnetic microspheres, they can be rapidly separated under the influence of an external magnetic field for use in cell separation and purification processes.

Drug carrier: Carboxylated magnetic microspheres can be used as drug carriers, which can target specific cells or tissues through surface modification for targeted drug delivery systems.

Magnetic analysis system: Combining immunochromatographic technology and magnetic analysis system, carboxylated magnetic microspheres can achieve quantitative and rapid detection, such as rapid detection of human chorionic gonadotropin, cardiac troponin, and HIV virus.

Biocompatibility and Suspension Stability: Carboxylated magnetic microspheres have good biocompatibility and suspension stability, making them suitable as carrier tools in biomedical research and practice.

AMAZING!
Color: Pink Blue
I have never written a review before, and I shop 4-5 days a week on Amazon. My 5 month old puppy LOVES these chew toys. When I first opened the box I was worried because they were so hard, but Poppy went crazy. He chews on them, tosses them and retrieves them, runs in circles around them and barks, and when he finally settles down will chew them and make these pig snort sounds of contentment. I have bought a lot of toys for my new puppy… But these are the best by far!

Toy broke in two
Color: Blue
This is a great toy for aggressive chewers. My reason for 3 stars is my dog dropped it on the tile floor the second day she had it and it broke in two. Not real happy with that. Update: The seller has been proactive and accepting of the very minor issue of the toy breaking. Responded within 24 hours and issued a refund. Because of their response I am changing my review to 4 stars.
