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.

It’s light weight and not greasy

I absolutely love this sunscreen! It’s lightweight, not greasy, and blends perfectly into my skin without leaving any white cast. It keeps my skin protected and glowing all day, even in the hot sun. I’ve noticed my face feels softer and more hydrated since I started using it. Definitely one of my must-haves I’ll keep buying this one for sure!

A perfect product for me!
Style: Sunscreen Stick, Size: 1.5 Ounce (Pack of 1)
This product is so convenient for travel. I am very fair and used this exclusively on my face and neck on my recent trip to South Africa. No sunburn, no smell, easy on, no breakout on my face. A perfect product for me!

My Family's Favorite Sunscreen!
Style: Sunscreen Stick, Size: 1.5 Ounce (Pack of 1)
This is our go-to sunscreen and my family has not used any other brand since discovering it about 5 or 6 years ago. The scent is pleasant, light, and tropical. Application is quick and easy. It goes on clear (not white) and looks a little greasy at first, but that is actually a positive because it helps you quickly see spots you (or your child) missed. It soon absorbs cleanly and the oily feeling goes away after a few minutes. The sunscreen works really well. My family has very pale, sensitive skin with eczema and easily burns in the sun. It does not irritate our skin at all and provides great coverage. This stuff works very well for us on vacation in Florida and on Bahamas/Caribbean cruises. It fits easily in a small bag and doesn't take up much room. With it being a solid, there's no worry of leaking. I love that you can hand everyone a stick and they can do most of the application themselves. Then we turn around and get the hard to reach spots on each other. And all done with clean hands that aren't getting messy. I would be so sad if this sunscreen is ever discontinued. We have over a dozen sticks in our house/car/luggage at any given time.
