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.

Excellent Family Passport Holder – Spacious, Secure, and Stylish!
Color: Black Wallet, Color: Black Wallet
I bought this passport holder for my family of five, and it has exceeded my expectations! It easily fits all five of our passports with room to spare — I’m confident it could hold a sixth passport comfortably. The layout is very well thought out, with six card slots, one clear ID slot, and a mesh zippered coin pouch that’s perfect for small items. There are also two roomy zippered compartments inside that could hold documents, tickets, or even some cash. I love the added features — an exterior slip pocket, a zippered pocket on the outside, and even a spot for a pen (which comes in surprisingly handy when traveling). The wristlet strap is a great bonus, making it easy to carry, and the main zipper closure keeps everything secure. The material feels durable and nicer than I expected for the price. It looks sleek, holds everything we need for travel, and keeps us organized on the go. I highly recommend this passport holder for anyone traveling with a family — it’s practical, well made, and very affordable.

Great wallet
Color: Black Wallet
These are great wallets; the size is a little big, they are roomy and not bulky. I do get a lot of compliments on the appearance of the style because of the size they are thinner than a bulky leather wallet and your stuff isn't scrunched up inside which makes it easier to locate. Love the look with the different colors and it seems to be a plus because of the card protector. I know they advertise as a vacation wallet but the comfort of the security and with the zipper closure makes it great for everyday use.

Single Passport Holder for Travel, RFID Travel Document Organizer - product as described
Color: B-Single-Lilac Purple
Holds my passport easily and a number of cards/driver's license. Fairly compact. Zipper is a little stiff. I had to zip close & leave it for a while to loosen the spine, shipped flat open.

Family travel document must have
Color: Black Wallet, Color: Black Wallet
I made a last minute call to purchase this travel wallet for my families recent trip to Mexico and I'm glad I did. There is a space for all of our passports, cards and cash and misc travel documents. We were able to stay organized and immediately file away important travel items in one easy pouch. In the hotel the size of the wallet made it easy to store in the hotel safe. The thick durable case also made me feel confident my travel essentials were RFID protected. I will definitely put this to the top of my travel essential list and would highly recommend this product for families, couples and singles for your next trip.
