Application of Magnetic Nanoparticles in Biology and Food Fields

Magnetic nanoparticle adsorbentswith a size of 1-100 nm are used for magnetic separation processes and are classified into different groups based on their magnetic properties: ferromagnetic, ferrimagnetic,
anti-ferromagnetic, diamagnetic, and paramagnetic. Due to their high surface to volume ratio, they have high energy levels and tend to reduce their energy levels. As a result, they have high loading capacity and limited dispersion. Magnetic nanoparticles are produced by different techniques, the most common of which is simultaneous deposition. These particles are very sensitive to parameters such as pH and temperature changes and ionic strength, and become stable by combining with carboxyl, phosphate and sulfate groups. These particles are used for polymer separation, removal of radioactive materials from wastewater, drinking water treatment, cancer treatment, enzyme immobilization, protein purification, food packaging and tracking techniques. These particles are extremely simple to use, cost-effective and low-risk.
