About this Research Topic
Magnetic (bio)sensors and magnetic (nano)material-based electrochemical (bio)sensors play a crucial role in advancing the field of analytical tools. In recent years, magnetic (nano)materials have been widely demanded given their benefits such as low toxicity, controllable size and shape, coating or modification routes, larger surface areas to volume ratio, the capability of promoting quicker electron transfer kinetic between the electrodes, and higher catalytic efficiencies. The incorporation of a magnetic (nano)material into a magnetic/or electrochemical detection platform can promote its sensitivity, stability and selectivity characteristics. Environmental pollution is one of the major current global problems. Contamination of agricultural and fishing areas, in addition to already being characterized as a serious problem and requiring surveillance tools, can lead to insecurity in the quality of food produced in these regions, which also requires analytical monitoring tools. As a result, the illness of the population requires safety in the drugs administered in the health area. However, to continue meeting these challenges, high-performance sensors are needed to achieve the most trace levels of concentration.
The enhanced performance of both electrochemical and magnetic sensors relies heavily on the choice of substrate and the modifier magnetic (nano)material immobilized on these platforms. Magnetic materials like iron oxide, ferrites of manganese, cobalt, nickel, and magnesium, CoPt and FeCo particles, and magnetic composite are promising materials in this field. Consequently, these materials can be combined with metal and metal oxide nanoparticles, carbon nanotubes, graphene, polymers, etc. The incorporation/immobilization of these magnetic nanomaterials in different platforms, including glassy carbon, carbon paste, boron-doped diamond, screen-printed carbon, 3D-printed electrode has increasingly pointed to promising sensors with different fields of application with attractive sensing capabilities. These advancements include enhanced sensitivity and lowered limit of detection, making them invaluable tools for the analysis of various biomolecules and biomarkers across a multitude of applications.
The aim of this Research Topic is to encompass various subjects concerning magnetic (nano)materials applied in the development of novel electrochemical and/or magnetic sensors. It will include topics such as the synthesis and characterization of magnetic (nano)materials or composites, the analysis of their electrochemical and/or magnetic properties, the advancement of novel electrochemical and magnetic devices, and the evaluation of their effectiveness in the fields of food, clinical or environmental.
