Magnetic Nanoparticles as an Efficient Tool for Analyte Extraction: Challenges and New Opportunities

Starting from the 2000s, the use of magnetic nanoparticles (MNPs) has begun to find a place in the studies of analyte extraction. Within this framework, the synergic collaboration in analytical chemistry and material sciences has developed several methods for the efficient and rapid extraction of analytes, especially in complex matrices. The main application of MNPs in the extraction step is in the environmental field for example in river water, lake water or industrial discharge samples. Other applications have been found in food and biological analysis, such as for urine or blood samples. In this chapter the use of metal nanoparticles for analyte extraction, and the areas of application, i.e., food, environment, and health, are explored. Moreover, the limits of these new methodologies, the new opportunities that are offered and the challenges of these techniques are highlighted.
