Product Name

Fe3O4@SiO2 nanoparticle

Product Overview

Silica-coated magnetic nanoparticles are a composite material consisting of a core of the magnetic material tri-iron tetraoxide (Fe3O4) and a shell of silicon dioxide (SiO2). The silica-coated magnetic nanoparticles are biocompatible and protect the biological activity of biological enzymes, DNA, and other biologically active substances, and can be used as a carrier for the controlled release of these substances to enable targeted therapy of drugs. Due to their many unique physical and chemical properties, core-shell structured nanomaterials have potential applications in superhydrophobic surface coatings, chemistry, magnetism, electricity, optics, biomedicine and other fields. In addition to this, CDF can also provide core-shell structures such as magnetic iron tetraoxide encapsulated in mesoporous silicon, gold-in-silicon, silver-in-silicon, gold-in-magnetism, and gold-in-silver.

Technical Parameter

Inner core diameter:50-500nm（TEM:/span>

Particle diameter:00-600nm（TEM:/span>

Product Features

Biocompatibility: The silica shell provides good biocompatibility, reducing the potential toxicity of the particles to the organism. 

Stability: The silica shell protects the inner core from oxidation and corrosion, increasing the stability of the particles in the organism. 

Easy functionalisation: the abundance of silica hydroxyl groups (Si-OH) on the surface of silica provides easy surface modification of the particles, which can be chemically linked to drugs, fluorescent markers, targeting ligands, etc. 

Good dispersibility: the silica shell helps to improve the dispersibility of the particles in aqueous and organic solvents and reduce agglomeration. 

Multifunctionality: different functional molecules can be combined to achieve a variety of biomedical functions, such as drug delivery, imaging, and therapy.

Application Fields

Targeted drug delivery: the silicon-coated magnetic nanoparticles can be used as a drug carrier, through the positioning of the external magnetic field, the drug will be delivered directly to the lesion site, to achieve targeted drug delivery, especially suitable for the diagnosis and treatment of specific types of cancer . 

Magnetothermal therapy: Using the heat generated by the silicon-coated magnetic nanoparticles inside the tumour cells, the heat generated by the external magnetic field can kill the tumour cells, which is a method of treating cancer in addition to surgery, chemotherapy and radiotherapy.

Magnetic Resonance Imaging (MRI) contrast agent: Due to their superparamagnetic properties, Si-encapsulated magnetic nanoparticles can be used as contrast enhancers for MRI, improving the clarity and contrast of the image.

Separation and enrichment of biomolecules: Si-encapsulated magnetic nanoparticles can be used for rapid separation and enrichment of specific molecules in biological samples, such as in proteomics research.

Biosensing: The magnetic properties of Si-encapsulated magnetic nanoparticles allow the development of novel biosensors for the detection of biomolecular interactions. 

Tissue engineering: Si-encapsulated magnetic nanoparticles can be used as bone tissue regeneration materials to promote osteogenic differentiation for tissue engineering research.

Good value, packed nice and small for travel or gifting, fluffs up thick
I ordered this throw - which, by the way, is OEKO-tex and CERTipur rated - because I don't have a white, fluffy throw in my otherwise cream and tan colored house. It arrived vacuum sealed and wrapped with a bow in a miniscule bag measuring 2" x 8" by 8". If you want to travel, say on a cruise ship or on a vacation for a week, and bring a comfort item, this is for you. It's so small that it won't take up hardly any room in your suitcase, but once you arrive at your destination, wow. It expands and fluffs up beautifully. It's super soft and really thick and comfy. It washes and dries very well. (On a cruise ship you could wash in the shower and wring, then hang to dry - it would probably dry overnight, or faster out on the balcony). I tried to get a close-up of the fluffiness but my camera wouldn't cooperate. At $15.99 it's competitively priced and comes with the added bonus of being vacuum sealed. Also has a instruction booklet for keeping the throw looking its best. Highly recommended.

A Perfect Throw Blanket For Your Lounging Area
I absolutely love this throw blanket, I sleep with it every night. It is incredibly soft and looks very nice laid out on a bed or couch. The size of it is perfect to cover me up, as im on the shorter side (5'4). It holds up well in a washing machine and dryer too. It keeps me nice and warm at night without getting overheated. Overall this blanket is a great addition to my home that I bought one for my husband and our daughter as well. I really like these blankets and think theyre worth their value.

Extra Cozy, Generously Sized, and Perfect for Snuggling
This throw blanket is an excellent buy. The price is great, and the sizing is even better than expected. It’s listed as 50 by 60 inches, and while the width is right at 50 inches, the length is definitely longer, closer to about 63 or 64 inches. You can see in my photos that it goes past the full length of my tape measure, which even has an extra couple of inches at the end with no markings. That extra length is a nice bonus. As for comfort, it absolutely lives up to the description. It’s warm, fluffy, and incredibly soft. It’s one of those blankets you just want to wrap up in and stay there. Perfect for getting cozy on the couch. I do have some larger throw blankets, and while those are great when you want something more like a full blanket, this size is much better as an actual throw. It’s very manageable, covers you generously, and still looks neat and intentional draped over a couch or chair instead of looking like a full blanket left out. The stitching is well done with no loose threads anywhere, and the overall quality feels really nice. It’s light but substantial and cozy enough to warm you up and definitely take the chill off. The white color is especially beautiful. It looks clean, fresh, and honestly feels like being wrapped in a fluffy cloud. It also comes packaged very nicely, making it a great option for gifting. This is a super cozy, well-made blanket with generous sizing and a great price. Definitely a five-star purchase.

Soft, Cozy, and Great Value Blanket
I bought this throw blanket for the couch and was pleasantly surprised by the quality. It arrived shrink wrapped, so at first it looked a bit flat, but once I opened it and let it fluff up, it became really soft and cozy. The microfiber material feels smooth and gentle on the skin, and the flannel fleece texture adds extra warmth without feeling heavy. I’ve been using it while relaxing in the evenings, and it’s the perfect balance of lightweight and warm. The striped design gives it a nice, clean look that works well with different decor styles. It also seems well made, with good stitching and no loose threads so far. For the price, it’s an excellent find. It looks good, feels comfortable, and is great for everyday use on the couch or even as an extra layer on the bed.

Like a Cloud! Very Nice Quality!
This throw is one of the nicest at this price point I've ever ordered. There are throws you get that you use every day and throws you get for decor and a statement. This is a very nice statement piece! I'm older with no pets and white doesn't scare me anymore. I wanted a great throw for my dark grey couch to set off my throw pillows and to just brighten up the space. This is a nice THICK throw, its fluffy compared to most throws in the $20-$30 price range and costs less! It is a 100% polyester fabric and will wash well every time. Simply designed with long puffy stripes and a nice texture they are not thin. It's a warm throw without being heavy at all. I would definitely buy others but only needed one in white this was a great value! It did not disappoint it was more than I expected!
