“…Yang et al [ 10 ] encapsulated Fe 3 O 4 MNPs with nonporous silica and a further layer of ordered mesoporous silica through a sol–gel process and further functionalized the outer silica shell by deposition of YVO 4 :Eu 3+ phosphors, achieving a magnetic coating separate from the inside luminescent material. Wang et al [ 12 ] fabricated poly(vinyl pyrrolidinone) Janus nanofibers with one side embedding Fe 3 O 4 MNPs and the other side containing [Eu(BA) 3 phen+Tb(BA) 3 phen] (BA = benzoic acid, phen = 1,10-phenanthroline) by parallel electrospinning, resulting in high luminescence intensity almost unaffected by Fe 3 O 4 MNPs.…”

Drug delivery systems (DDSs) limited to a single function or single-drug loading are struggling to meet the requirements of clinical medical applications. It is of great significance to fabricate DDSs with multiple functions such as magnetic targeting or fluorescent labeling, as well as with multiple-drug loading for enhancing drug efficacy and accelerating actions. In this study, inspired by the dual-chamber structure of rapeseed pods, biomimetic magnetic–luminescent bifunctional drug delivery carriers (DDCs) of 1.9 ± 0.3 μm diameter and 19.6 ± 4.4 μm length for dual drug release were fabricated via double-needle electrospraying. Morphological images showed that the rapeseed pod-like DDCs had a rod-like morphology and Janus dual-chamber structure. Magnetic nanoparticles and luminescent materials were elaborately designed to be dispersed in two different chambers to endow the DDCs with excellent magnetic and luminescent properties. Synchronously, the Janus structure of DDCs promoted the luminescent intensity by at least threefold compared to single-chamber DDCs. The results of the hemolysis experiment and cytotoxicity assay suggested the great blood and cell compatibilities of DDCs. Further inspired by the core–shell structure of rapeseeds containing oil wrapped in rapeseed pods, DDCs were fabricated to carry benzimidazole molecules and doxorubicin@chitosan nanoparticles in different chambers, realizing the sequential release of benzimidazole within 12 h and of doxorubicin from day 3 to day 18. These rapeseed pod-like DDSs with excellent magnetic and luminescent properties and sequential release of dual drugs have potential for biomedical applications such as targeted drug delivery, bioimaging, and sustained treatment of diseases.

“…59 Janus nanostructures with tunable magnetic and photoluminescent properties were prepared from Eu(benzoic acid) 3 1,10-phenanthroline, Tb(benzoic acid) 3 1,10-phenanthroline, Fe 3 O 4 nanoparticles, and PVP as the polymer used as a spinning agent. 60 Another method was described by Wang et al They also used PVP in ethanol with Tb(benzoic acid) 3 1,10-phenanthroline to create fluorescence properties, but added Fe 3 O 4 and PVP in ethanol for the magnetic part. Conjugate electrospinning was performed using two syringes with plastic spinnerets for the two solutions and a rotating drum as collector, resulting in aligned nanofibers with similar diameters.…”

“…Measuring magnetic properties can be done by most common instruments which are used to examine magnetic thin layers or nanostructures, such as superconducting quantum interference device (SQUID), 65 vibrating sample magnetometer (VSM), 60 or alternating gradient magnetometer (AGM). 66 Optical methods, such as magneto-optical Kerr effect (MOKE), have not yet been reported in the literature for investigations of electrospun nanofiber mats; the roughest materials examined in this way are to the best of our knowledge paper coated with magnetic flakes.…”

One-dimensional materials, such as nanowires, nanotubes, or nanofibers, have attracted more and more attention recently due to their unique physical properties. Their large length-to-diameter ratio creates anisotropic material properties which could not be reached in bulk material. Especially one-dimensional magnetic structures are of high interest since the strong shape anisotropy reveals new magnetization reversal modes and possible applications. One possibility to create magnetic nanofibers in a relatively simple way is offered by electrospinning them from polymer solutions or melts with incorporated magnetic nanoparticles. This review gives an overview of most recent methods of electrospinning magnetic nanofibers, measuring their properties as well as possible applications from basic research to single-cell manipulation to microwave absorption.
