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.

Not good if you need Whole Foods gift cards
If you want to buy Whole Foods gift cards (which is why I got it) it flags it for fraud and doesnt let you. I was told you can spend at Whole Foods but not buy WF gift cards, even though it is a Prime Credit Card. Also if you buy WF gift cards online, you dont get the rewards since its from a gift card company and not Whole Foods.

A Truly Ergonomic Mouse
Number of Items: 1
Other not completely flat mice claim to be "ergonomic", but the only way to completely remove stress from your forearm when using a mouse is with a "vertical" mouse. My 2020 K75575WW Kensington ergonomic vertical mouse developed a problem with the left button "stuttering" so that it sent multiple button clicks when pressed just once. I liked the Kensington quite a bit. But it always just a little bit on the "not quite as solid as I would like" side, and failing after just 2.5 years confirmed this. So I wanted a more solidly build mouse. A search for "ergonomic mouse review" showed that the Logitech MX Master 3S was clearly the best ergonomic mouse available. At $100 it was several times more expensive as others including the latest Kensington vertical mouse. But sometimes furgal doesn't mean the least expensive. Sometimes it can mean the most expensive if that comes with better performance, features and lifespan. So I ordered it. And while it is indeed an incredible mouse, the angle is only about 20 degrees. The result is that while there is some reduction in forearm stress compared to a flat mouse, it wasn't enough for me. By the end of my very long days driving my mouse almost as much as I drive my keyboard, I could feel the tension building up in my forearm. So after a week I returned it and bought this Logitech MX Vertical. It is slightly less expensive than the MX Master 3S, but still much more expensive relative to other options. And while it is lighter and a little less substantial feeling in my hand than the MX Master 3S, it still feels very firm and solid. Most importantly keeps my hand in the neutral position with my fingers at about 70 degrees. A great feature of the MX Vertical shares with the MX Master 3S is the thumb rest. The Kensington didn't have this and so my thumb rested on the desktop. If it was a bit warm and my hands would sweat my thumb wouldn't slide smoothly and I would have to lift my thumb off the desk when I went to move the mouse. Not a horrible thing, but if you spend 8+ hours mousing around it gets tiresome. The button clicks are crisp. Best of all when the button bottoms out it feels like it is pressing against the case. It doesn't feel like travel is being limited by the switch itself bottoming out like the Kensington felt like it did. My hope is that this will keep the switch from wearing out so fast as happened with the Kensington. One slight negative of the MX Vertical is that I don't feel like I am quite as accurate in being able to move the cursor to a specific spot on the screen without some amount of conscious effort. Instead it doesn't go exactly in the direction I intended and overshoots where wanted it to stop. As such it might not make the best mouse for video games. [UPDATE: There is a bit of a learning curve in moving the mouse accurately. In the last couple weeks my need to make a more conscious effort to move the mouse to a specific spot on the screen is going down. Still think it is likely to not be as accurate as a flater mouse]

The Logitech MX Vertical Wireless Mouse is an outstanding ergonomic mouse that truly reduces wrist and forearm strain. Its vertical design feels natural and comfortable, even during long hours of use, making it a great choice for anyone concerned about repetitive strain or discomfort. The mouse connects seamlessly via Bluetooth or the included USB receiver, and the ability to switch between three different devices is incredibly convenient for multitasking. The precision and smooth tracking make it excellent for both work and creative tasks. Overall, this mouse combines comfort, functionality, and versatility in one sleek package. It’s well worth the investment for anyone looking to improve ergonomics and productivity.
