Magnetic nanoparticles

Magnetic nanoparticles (MNPs) are a class of nanoparticle that can be manipulated using magnetic fields.[citation needed] Such particles commonly consist of two components, a magnetic material, often iron, nickel and cobalt, and a chemical component that has functionality. While nanoparticles are smaller than 1 micrometer in diameter (typically 1–100 nanometers), the larger microbeads are 0.5–500 micrometer in diameter. Magnetic nanoparticle clusters that are composed of a number of individual magnetic nanoparticles are known as magnetic nanobeads with a diameter of 50–200 nanometers.[1][2] Magnetic nanoparticle clusters are a basis for their further magnetic assembly into magnetic nanochains.[3] The magnetic nanoparticles have been the focus of much research recently because they possess attractive properties which could see potential use in catalysis including nanomaterial-based catalysts,[4] biomedicine[5] and tissue specific targeting,[6] magnetically tunable colloidal photonic crystals,[7] microfluidics,[8] magnetic resonance imaging,[9] magnetic particle imaging,[10] data storage,[11][12] environmental remediation,[13] nanofluids,[14][15] optical filters,[16] defect sensor,[17] magnetic cooling[18][19] and cation sensors.[20]
