Abstract

The present study focused on the ability to combine magnetic NMs to enable the use of their synergistic additives and new properties for the development of different sensing systems in various fields. A novel kind of integration of magnetic NPs in the sensing systems results in its significant improvement of sensitivity, limit of detection and stability. The applicability of NPs as colourimetric sensors, biosensors and sorbents is inevitable. Accordingly, the SPIONs used for drug delivery in vivo sized from 10 to 200 nm make them able to escape from attacks macrophages of the immune system part (>200 nm) and could avoid renal excretion (<10 nm). A novel Fe3O4@Pt NPs as a paper-based colourimetric sensor has determined LOD for glucose was 0.36 μM in a human sample. Moreover, PPY-based biosensor gave valid glucose evaluation in fruit juices and non-alcoholic drinks with LOD of 26.9 μM. Chemical approaches are the most used, even 90%. Characterization of nanostructures is done mainly by transmission electron microscopy, thermogravimetric analysis, X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy. For the production and commercialization of the MNPs, controlled size, standardized, cost-effective and controlled synthesis methods are required. The focus on the green character of magnetic NMs, their synthesis and green properties would advance future studies, particularly for the development of non-toxic NMs for their safer further application.
