What is Ferromagnetic Paper?

What is Ferromagnetic Paper? Ferromagnetic paper is formed by impregnating ordinary paper or newspaper with "magnetic nanoparticles". It can be used to make low-cost "micro-motors" for surgical instruments, tiny tweezers to study cells, tiny robots and tiny speakers. At present, the researching people will also ferromagnetic origami paper, to study more complicated design. Ferromagnetic paper [...]

Types of Magnetic Nanoparticles (MNPs)

The physical and chemical properties of magnetic nanoparticles largely depend on the synthesis method and chemical structure. In most cases, the particles range from 1 to 100 nm in size and may display superparamagnetism. Types of magnetic nanoparticles Oxides: ferrites Ferrite nanoparticles or iron oxide nanoparticles (iron oxides in crystal structure of maghemite or magnetite) [...]

A Magnetic Handle Put into Nanoparticles

A long-sought goal of creating particles that can emit a colorful fluorescent glow in a biological environment, and that could be precisely manipulated into position within living cells, has been achieved by a team of researchers at MIT and several other institutions. The finding is reported this week in the journal Nature Communications. The new [...]

Applications of Magnetic Nanoparticles

Applications of Magnetic Nanoparticles Magnetic nanoparticles are a class of nanoparticle which can be manipulated using magnetic field gradients. Such particles commonly consist of magnetic elements such as iron, nickel and cobalt and their chemical compounds. While nanoparticles are smaller than 1 micrometer in diameter (typically 5–500 nanometers), the larger microbeads are 0.5–500 micrometer [...]

Magnetic Nanoparticles

Magnetic Nanoparticles When a piece of a magnetic material is made smaller and smaller, is acquires simpler magnetic domain structure since less domain walls are needed in order to minimize the stray field energy. The extreme limit is represented by single domain particles. Below a size of about 500 nm it is no [...]

Magnets to Remove Cancer Cells

Researches at Georgia Institute of Technology have found a new way to identify and potentially eliminate cancerous cells, in ovarian cancer. With ovarian cancer, metastasis happens when cells slough off the primary tumor and drift free in the abdominal cavity. If scientists could use the magnetic nanoparticles to trap drifting cancer cells and pull them [...]
