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.


Technical Parameter

 

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.

Burned my already sensitive feet, too big
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
Feels icky, and the heat gets trapped and literally felt like my feet were being burned by these. The bottoms of these feel prickly and they are way too big. You have to sit still and cannot walk in them.

Just as good as paraffin wax
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I might prefer these socks over paraffin wax. They are comfy and very moisturizing. I use these socks once a week to keep the heels and soles of my feet moisturized between pedicures. I rinse with warm, soapy water then hang to dry. They are hard to walk in, but there's a saying printed in the socks that's says something to the effect of "take a break, stay off your feet" lol I love that as a reminder to put my feet up and relax

Love these!
Color: Pink & Beige, Size: Small(fits up to size 7)
Love these! As I write this review, I’m sitting in my recliner with these on. I have had other silicone socks in the past and would like to share a few of the things that I have learned. These fit great! The others were 2-3 sizes too big because you could not order a size. I wear a size 7 women’s shoe. I got the smaller size. I walked around my apartment in my old ones and they got kinda yucky. Now, I sit in my recliner, put them on and chill for a few hours. I now take them off and put in a ziplock bag so they stay nice and clean (no cat hair!). I use them once a week usually on Saturday or Sunday as I’m a working girl. Also, I use Auqaphor before I put them on and put cotton socks on after I’m finished. Your feet will be SO soft. This is not a one and done…I do this every week especially during sandal season! I know this was lengthy and I hope you got some tips.

Absolute game changer for chronically dry feet/cracked heels
Size: S (up to size 7)-Beige
I had recently bought a pair of silicone heel/ankle wraps to fill out my boot a little since I noticed my heels were lifting when I was skating. I tested them out around the house and noticed they left my heels softer while the rest of my sockless feet got quite dry. So I got these full foot silicone socks to see the effect of having my whole foot covered. I slather the entirety of my feet with Dr. Scholl's Severe Cracked Heel Restoring Balm (love how convenient it is to apply it to my feet with the solid stick form) and then slip them into these silicone socks. After just a couple hours, when I pull out my feet they're (a teeny bit sweaty at first), but then overall soft and smooth and have absorbed the balm fully leaving barely any residue in the silicone sock. I find these silicone socks generally comfortable; I wear them in the evenings while relaxing on the couch, take them off after a couple hours and let my feet breathe a bit, and then reapply my balm and socks and wear them to bed. If I wake up in the middle of the night, which I almost always do (not because of the socks), I'll take the socks off and allow my feet to breathe again. I wear a woman's size 6 shoe and the small size is pretty comfortable. However, I made the mistake of wearing them while being on my feet for a couple hours straight during household chores -- they must've somehow cut off my circulation a bit with the standing, so I wouldn't recommend wearing these silicone socks while being active. And since they're not exactly my foot size, they slide around sometimes and will start to feel tight at my big toe. But if that happens, I just tug on the toe area of the sock to give my big toe more wiggle room and problem solved. Prior to wearing these socks, I was soaking and doing heavy duty exfoliation of my feet every week. These socks seem like they'll work to help me extend the time between soakings and exfoliations. The 5 pack is a great value. So far none have torn, so they seem rather durable. Not sure what I could even do to tear a hole in these.
