Question

Please could any one write a paragraph or two to explain the application of magnetic nanoparticles ( iron oxide ) in biotechnology, biomedicine and engineering. Please I really need clear explanation for each of those domains

Answer 1

Answer :

Iron oxide nanoparticles have dominated applications compared to other nanoparticles used.

In general applications of magnetic nanoparticles is categorized as

• Information storage
• Bioseparation
• Biosensor
• Catalysis
• Molecular imaging
• Gene delivery
• Drug delivery
• Biomaterials

Biotechnology.

Biotechnology is a system using biological systems to develop or create different products.

In biotechnology, the essential features of nanoparticles are their dimension, their magnetic properties and their capability of carrying active biomolecules for selective task. The active biomolecules bound to these nanoparticles can then be released. Example: they are used for gene delivery in nucleus of a yeast cell to incorporate a desirable character. Say disease resistance or better fermentation qualities.

Biomedicine

Biomedicine is studying human body from theoretical aspects.

Assemblies of super paramagnetic nanoparticles are widely used in various fields of bio medicine. Important applications are

• Magnetic biodetection
• Magnetic hyperthermia
• Magnetic particle imaging
• Magnetic separation
• Drug delivery

In drug delivery magnetic nanoparticles help in fine tuning of target. Force can be applied in nano molecular level by these nanoparticles by the application of external magnetic field.

Bioengineering

Bioengineering is application of principles of biology and tools of engineering to create usable, tangible and economically viable products.

Bioengineering is actually very much linked to biotechnology and biomedicine in a practical point of view. Some of the new advacement and ongoing researches are in

• Cellular therapy involving cell labeling
• Cell targeting
• To separate and purify cell populations
• Tissue repair
• Magnetic resonance imaging
