Abstract

Nanoparticles are smaller than 100nm. Size of particle depends upon the method that is used for synthesis of nanoparticles. Magnetic nanoparticles consist of iron, cobalt and nickel and their chemical compounds. Their safety or toxicity is major concern for use in food. Magnetite, hematite and meghemite are types of magnetic nanoparticles. Magnetite (Fe3O4) common among the magnetic iron oxide nanoparticle that is used in food industry. Magnetite is getting popular due to its super paramagnetic properties and lack of toxicity to humans. Different methods are used to synthesize magnetic nanoparticles. Upon contact with air these particles loses magnetism and mono-dispersibility. To overcome this problem these nanoparticles are coated with natural or synthetic polymers, metals, organic and inorganic substances to create stable and hydrophilic nanostructures. Due to easy separation with magnet these magnetic nanoparticles are used as an affinity probe to remove bacteria from different food samples and have food related applications e.g, protein purification, enzyme immobilization and food analysis. These magnetic nanoparticles also used for removal of heavy metals and used in medical field.
磁铁矿(Fe3O4)的合成、功能化及其应用
纳米颗粒小于100nm。颗粒的大小取决于用于合成纳米颗粒的方法。磁性纳米颗粒由铁、钴和镍及其化合物组成。它们的安全性或毒性是食品中使用的主要问题。磁铁矿、赤铁矿和镁铁矿都是磁性纳米颗粒。磁铁矿(Fe3O4)在食品工业中使用的磁性氧化铁纳米颗粒中常见。磁铁矿因其超顺磁性和对人体没有毒性而越来越受欢迎。合成磁性纳米颗粒的方法不同。与空气接触后,这些颗粒失去磁性和单分散性。为了克服这个问题,这些纳米粒子被天然或合成聚合物、金属、有机和无机物包裹,以创造稳定的亲水纳米结构。由于易于用磁铁分离,这些磁性纳米颗粒被用作亲和探针,从不同的食品样品中去除细菌,并具有与食品相关的应用,如蛋白质纯化,酶固定和食品分析。这些磁性纳米颗粒还可用于重金属的去除和医学领域的应用。
