Some structures of materials that can be tailored to a nano-scale dimension exhibit wonderful features like physical and chemical properties. When properties of metals changes, it can be used in various applications. There are magnetic metals like iron, nickel and cobalt that can be manipulated with the help of magnetic field gradients.
When there is a need for a catalyst, these magnetic nanoparticles are ideal for usage. The nano material based catalysts are used extensively in many sector these days. In the bio medical field especially, these have potential usage. In bio-medicine drug delivering is the important part of the treatments.
Here, magnetic particles are utilized by attaching them to the device and thereafter monitoring, manipulating and transporting them to the targeted species. This will take the drug to the necessary targeted place. The process cannot happen on tis own, there is a need for an external magnetic force and when applied, the nano particles work astoundingly well!
Even in their bare form, magnetic nanoparticles can be used in many applications. One of the potential use of the particles is in the surface coating. The interaction of the particles with the environment can be controlled by ensuring stability and by preventing agglomeration. When done so, it provides steric repulsion. The biologically active molecules in the drugs might react with environment and to prevent it, these particles are used as coatings.
In chemical reactions where acidic content is more, the magnetic nanoparticles are coated with silica shell. Here, bare magnetic particles cannot be used.
These particles have a very large surface area and hence it allows attachment of extractable species in that space. Hence, it acts as a very good drug delivering agent. As it functions well with selected ligands it allows for targeted drug delivery to the specific location. This is ideal in curing many diseases and especially for spotting cancer cells.
These acts as a magnetic tuneable colloidal photonic crystals. These manipulate the flow of light and these are widely used in thin-film optical industry. If you are planning to buy these nano magnetic materials, then this is the right time to order in bulk!
