Magnetic Nanowires for Nanobarcoding and Beyond

Abstract

Multifunctional magnetic nanowires (MNWs) have been studied intensively over the last decades, in diverse applications. Numerous MNW-based systems have been introduced, initially for fundamental studies and later for sensing applications such as biolabeling and nanobarcoding. Remote sensing of MNWs for authentication and/or anti-counterfeiting is not only limited to engineering their properties, but also requires reliable sensing and decoding platforms. We review the latest progress in designing MNWs that have been, and are being, introduced as nanobarcodes, along with the pros and cons of the proposed sensing and decoding methods. Based on our review, we determine fundamental challenges and suggest future directions for research that will unleash the full potential of MNWs for nanobarcoding applications.

Electrodeposition as a Tool for Nanostructuring Magnetic Materials

“…Regarding green energies and energy storage, nanowires have been proposed as building blocks of novel rare-earth free permanent magnets [154,155] and a bonded magnet composed of ferrite nanoparticles and electrodeposited ferromagnetic nanowires has been recently reported [73]. Electrodeposited nanowires have been also used in barcoding [156], microwave electronics [157] and sensing [158] applications. An approach for the upscaling of the fabrication of electrodeposited nanowires has also been recently proposed, trying to close the gap between the development of lab prototypes and real industrial applications [42].…”

Template-based electrodeposited nonmagnetic and magnetic metal nanowire arrays as building blocks of future nanoscale applications

“…For the past few decades, nanomaterials ranging from nanoparticles to nanowires (NWs), have been a source of excitement in the scientific and research community, and captured imaginations in many current and emerging fields [11][12][13][14]. These nanomaterials are expected to be employed as ultraprecise, highly-efficient and nonvolatile components of next-generation state-of-the-art nanodevices, including racetrack memories [15,16], batteries [17,18], solar cells [19,20], capacitors [21,22], conductive electrodes [23,24], sensors [25,26], absorbers [27,28], magnetoresistive recording heads [29,30], and magnetologic gates and processors [31,32].…”
