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.

Concentration:10 mg/mL

Surface carboxyl content: 2000 nmol/mg:μm:/span>

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.

REALLY CUTE SHOE BUT CUT WAY TOO SMALL!
Size: 8, Color: Black Patent
I received the black patent leather shoes today and they are so cute! Sadly I need to return them because they are cut way too small. I normally wear a 7.5 or 8 on dress shoes so I ordered the 8. They are so tight across the top that it's uncomfortable as soon as I put them on. They are smaller than a normal size 8 dress shoe. The big toe area is extremely uncomfortable because it doesn't allow any room for it at all, so my big toe just presses against the side and end of the shoe without even walking in them. I have very narrow feet and these still are too small for me. So I am returning them and I already ordered a 8.5 W and hope that will fit much better. The patent leather is very cute and adds just enough dressy that I can wear them with slacks or my Capri jeans. I like the slip on and the cushion foot bed because it feels soft.

Love these flats!
Size: 9 Wide, Color: Black White Faux Snake Skin, Size: 9 Wide, Color: Black White Faux Snake Skin
One of my favorite pair of flats! I’ve had these for several years and they are still comfortable, in good shape and really add a little spice to my outfits. I can wear these all day and not have any foot pain or discomfort as a result. The quality is good, fit is perfect and I tend to have difficulty with shoes due to bunions. Love these!!

LOVE LOVE.
Size: 7.5 Wide, Color: Beige
I love these shoes so much I had to write a review. So comfortable. Cushioned. Fits perfectly especially if you are more on the wide side. They are soft. Flexible. Easy slip ons you can walk around in all day. I want to try more colors.

Great buy
Size: 12 Wide, Color: Black Faux Leather
I absolutely love these Amazon Essentials Belice Ballet Flats! They are so comfortable right out of the box and fit my feet perfectly. I can wear them all day without my feet hurting, which is hard to find with flats sometimes. They’re also really cute and go with almost everything I wear. I find myself reaching for them all the time because they’re both comfy and pretty. Definitely a great everyday shoe, especially for the price!

Loooove these shoes!
Size: 7.5 Wide, Color: Chestnut Brown Faux Leather
I have these in several colors, and they’ve become a true staple in my wardrobe. The Amazon Essentials Women's Belice Comfortable Slip-On Ballet Flats are exactly what I look for in an everyday shoe—simple, versatile, and comfortable right out of the box. The slip-on design makes them super convenient for busy days, and they pair effortlessly with everything from jeans to dresses to work outfits. They’re lightweight but still feel supportive enough for all-day wear, and I appreciate that they don’t require a break-in period. The fit is generally true to size, and the variety of colors makes it easy to stock up and rotate depending on the outfit. Overall, these are reliable, easy-to-wear flats that offer great value for the price. Not flashy, just consistently comfortable and practical—which is exactly why I keep coming back to them.
