“…This oxide layer makes them biocompatible [142] and biodegradable [143], [144] to the point that they are approved for in vivo use in humans [145]. This oxide layer can be thickened by annealing [26] and functionalized to enhance colloidal stability [146], target certain cells [25], [102], [146] and label them [147]. Since the aspect ratio of NWs can be tailored at the fabrication step, they can take shapes from the semisphere/cube to the nanowire geometries.…”

“…• They can be excited with lasers or alternating magnetic fields up to hundreds of kilohertz and produce motion and/or heat [21]- [23]. This makes them attractive for biomedical applications [24], targeting cancer cells when they are properly functionalized [25], [26] or as MRI contrast agents working at around hundredths of megahertz [27], [28]. • Arrays of NWs have been used as electromagnetic pulse detectors [3], microwaves circulators or phase shifters [29]- [32] at 10 -40 GHz frequencies.…”

Cylindrical magnetic nanowires feature unique properties, which make them attractive for fundamental research as well as novel applications. These one-dimensional structures introduce a pronounced shape anisotropy that together with material selection can strongly affect the magnetic properties and can be tuned by incorporating segments of different materials or diameters along the length. They attract a large interest in the scientific community, ranging from physicists to material scientists to bioengineers. Consequently, these nanowires are developed for and employed in very diverse applications in medicine, biology, data and energy storage, catalysis or microwave electronics, among others. In this review we investigate the most active emerging applications of cylindrical nanowires grown in alumina templates by electrochemical deposition. This method has several key features, including low cost and a high level of control over the design. A fundamental property that distinguishes those applications is the operating frequency, which we chose to apply as an underlying structure for this review. With this we attempt to provide a wide and organized view of applications based on cylindrical magnetic nanowires with a focus on tailored physical and chemical properties.
