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:-15nm

Particle diameter:0-20 nm

Appearance:Brown powder

Concentration:1-10 mg/ml

Solvent:ETOH

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.

My Dog's Favorite Nylabone
Flavor Name: Bacon & Beef, Size: X-Small
I've been testing out Nylabones the last couple months for my chihuahua puppy. He's a heavy chewer and too easily tears apart many of them, then others are too hard and I take them away because I fear for his teeth. This set is his favorite so far. He doesn't care about the peanut butter ones, loves the beef one, and is absolutely obsessed with the bacon one. He walks around with it in his mouth whenever he goes anywhere. Unfortunately, my senior chihuahua also loves the bacon one and there is now an ongoing feud over it, so guess I'm buying another pack. I like that these are just a little chewy without being too soft, but I still recommend keeping an eye on them as even my puppy has managed to start to get little pieces off. But it's more as frayed strings than chunk like I've had happen with some of the softer ones.

Good for satisfying destruction urges
Flavor Name: Bacon & Beef, Size: X-Small
I have a 30 pound dog who doesn’t want a super hard chew toy, but something that he can destroy into pieces. It really helps with his destruction urges. Even though my dog is 18 months old, this puppy chewer is perfect for him. Once he chews it up into little pieces, I am able to pick them up, and by the time he is done, he is relaxed and or asleep. Highly recommend for puppies, of course, but if you have a dog who needs to destroy, this is the perfect thing to do that with! It is good value for the money and better than other household items that he could be chewing on.

Perfect for the aggressive chewer
Color: Purple
I purchased these because I have a 1-year-old black lab redbone coonhound mix who destroys every toy and Bone. I have gotten him in a short amount of time... These things have outstanded this little guy and he is still enjoying them! Keeps him occupied and satisfies his chewing for hours! And he leaves my shoes alone haha

Best for all chewers!
Color: Purple, Color: Purple
I purchased in February and waited until ive had them long enough to make a justified review. I have a very VERY aggressive chewer. He destroys every toy he gets within minutes or a hour. We didnt expect much out of these but why not. Let me tell you... they only have small teeth dents. No cracks, no breaks, no chunks missing, none in the trash, no bleeding gums... nothing. My chewer loves them. First day he just stared at them like they were alien objects but after we played fetch a few times it was on!! Now all three dogs chewer on them. I would say im purchasing again but I dont know when that will be lol I highly recommend to anyone!! Photo is taken today 6/4/26
