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.

best toys ever!
I seriously can’t recommend these dog toys enough! My puppy is usually super picky and gets bored easily, but she was OBSESSED with these right away. The moment I gave them to her, she wouldn’t put them down—running around, chewing, tossing them in the air, everything. It kept her entertained for hours, which is a lifesaver. They’re also really durable (which surprised me because she can be a little destroyer 😅), and they seem safe and well-made. I love that they help with her teething too—she goes for these instead of my shoes now, which is a huge win. If you have a puppy with lots of energy or who needs something to stay busy, these are 100% worth it. I’ll definitely be buying more!

A must to keep on hand for your furry friend.
My dog absolutely loves these Pink Puppy collection of toys, they keep her safely busy for hours. They seem chew resistant and durable. She loves the pink ball and the sound of the material inside the Elephant. Great buy, I give her two every holiday.

Puppy toys
These are SO CUTE! They are VERY SMALL and for PUPPIES, not for full grown doggies. My puppy is teething and she loves them. Great price and good quality!!

Excellent Value
I love these toys! I bought them for a litter of German Shepherd puppies for their first toys. They instantly swarmed the elephant and cuddled with it. It is their favorite toy to this day. I bought another set so they had another one. They play with everything except the ropes, since they unraveled them early on I threw them out. They have cuddled with them and played with them for almost 3 months. I wash the teething toys in the sink with dial soap, and the plush toys on regular cycle in the machine, multiple times per day since I bought them. They look brand new each time. Only the little hearts and stars split open, but that was my adult dogs' fault. I didn't realize she was reaching into their playpen and taking their toys. Our Rottweiler and bulldog just love the teething toys, which cracks me up. Basically, all the dogs like this kit, but they are pretty good about not destroying toys, at least not right away. They figured out I take them away when they do, so they do their best. I doubt they will hold up to any dog deliberately trying to tear them up (like any toy), so supervision is recommended.
