“…It is not only owing to their outstanding soft magnetic properties including high saturation magnetization ( M s ), high permeability ( μ ), high Curie Temperature ( T c ) and low coercivity ( H c ) and energy loss123456, but also owing to their widely applications in electromagnetic microwave absorption, magnetic refrigeration systems, magnetic recording devices, magnetic resonance imaging and sensors789. Generally, Fe-Ni alloys are basically classified into two categories based on the mass ratio of Fe: Ni.…”

Iron-nickel (Fe-Ni) alloy nanoribbons were reported for the first time by deoxidizing NiFe2O4 nanoribbons, which were synthesized through a handy route of electrospinning followed by air-annealing at 450 °C, in hydrogen (H2) at different temperatures. It was demonstrated that the phase configurations, microstructures and magnetic properties of the as-deoxidized samples closely depended upon the deoxidization temperature. The spinel NiFe2O4 ferrite of the precursor nanoribbons were firstly deoxidized into the body-centered cubic (bcc) Fe-Ni alloy and then transformed into the face-centered cubic (fcc) Fe-Ni alloy of the deoxidized samples with the temperature increasing. When the deoxidization temperature was in the range of 300 ~ 500 °C, although each sample possessed its respective morphology feature, all of them completely reserved the ribbon-like structures. When it was further increased to 600 °C, the nanoribbons were evolved completely into the fcc Fe-Ni alloy nanochains. Additionally, all samples exhibited typical ferromagnetism. The saturation magnetization (Ms) firstly increased, then decreased, and finally increased with increasing the deoxidization temperature, while the coercivity (Hc) decreased monotonously firstly and then basically stayed unchanged. The largest Ms (~145.7 emu·g−1) and the moderate Hc (~132 Oe) were obtained for the Fe-Ni alloy nanoribbons with a mixed configuration of bcc and fcc phases.

“…Due to their high saturation magnetisation, Fe-Co nanoparticles have been utilised in biomedical applications such as contrast agents for MRI [78][79][80] and magnetic hyperthermia [92][93][94][95][96][97]. Iron nickel (Fe-Ni) nanoparticles have a high Curie temperature and high saturation magnetisation properties and are mainly used as contrast agents for MRI [81]. Copper nickel (Cu-Ni) nanoparticles show good Curie temperatures and magnetic properties with their main use being for magnetic hyperthermia [98][99][100].…”

“…These properties allow for its use in many biomedical applications; bioimaging 34,41,56,62], hyperthermia [20,21,[31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46]55], drug delivery , cell labelling [26,70] and gene delivery [71][72][73][74][75][76][77]. From our most recent review, it was seen that other magnetic nanomaterials such as Fe-Co, Cu-Ni, Fe-Ni, Co-Fe 2 O 4 and Mn-Fe 2 O 4 , nanoparticles are being investigated for use in bioimaging [78][79][80][81][82][83][84][85][86][87][88][89][90][91]109], hyperthermia [92]…”

There is a growing interest in the use of nanosystems such as nanoalloys, bimetallic nanoparticles, metallic nanoparticles and magnetic nanoparticles in biomedical applications. These applications can be as diverse as hyperthermic treatments; targeted drug delivery; bio-imaging; cell labelling and gene delivery. The use of nanoalloys in these applications has received only limited attention due to the fact that there were many unanswered questions and concerns regarding nanoparticles and nanoalloys such as their stability over time, tendency to agglomerate, chemical activity, ease of oxidation, biocompatibility and cytotoxicity. In this chapter we survey current applications and advances in magnetic nanoparticles used in these biomedical applications so as to understand the materials properties that can pave the way for the use of nanoalloys as a potential alternative or improve solutions that are offered by current materials.
