“…Chitosan, poly-(D)-glucosamine is a favorable dispersant for many types of small particulates, including Fe 3 O 4 magnetic nanoparticles and can be used in the preparation of fibers by electrospinning (30)(31)(32)(33). For electrospining, chitosan as a weak base was dissolved in acetic acid (weak acid) and the solution showed a good stability.…”

Abstract. A poly(vinylalcohol) (PVA) electrospun/magnetic/chitosan nanocomposite fibrous cross-linked network was fabricated using in situ cross-linking electrospinning technique and used for bovine serum albumin (BSA) loading and release applications. Sodium tripolyphosphate (TPP) and glutaraldehyde (GA) were used as cross-linkers which modified magnetic-Fe 3 O 4 chitosan as Fe 3 O 4/ CS/TPP and Fe 3 O 4/ CS/GA, respectively. BSA was used as a model protein drugs which was encapsulated to form Fe 3 O 4 /CS/TPP/BSA and Fe 3 O 4 /CS/GA/BSA nanoparticles. The composites were electrospun with PVA to form nanofibers. Nanofibers were characterized by field emission scanning electron microscopy (FESEM) and Fourier transform infrared spectroscopy (FTIR). The characterization results suggest that Fe 3 O 4 nanoparticles with average size of 45 nm were successfully bound on the surface of chitosan. The cross-linked nanofibers were found to contain uniformly dispersed Fe 3 O 4 nanoparticles. The size and morphology of the nanofibers network was controlled by varying the cross-linker type. FTIR data show that these two polymers have intermolecular interactions. The sample with TPP cross-linker showed an enhancement of the controlled release properties of BSA during 30-h experimental investigation.

“…[12][13][14][15][16][17], many researches are focused on their preparations and properties in recent years. Some preparations of Fe 3 O 4 @RE complexes core-shell structure nanoparticles (NPs) [18][19][20] and 1D magnetic-luminescent bifunctional nanomaterials [21,22] have been reported. However, in these papers, white light emitting, as the most commonly used emitting color, is not achieved.…”

New-typed magnetic and color-tunable bifunctional Janus nanofibers have been successfully fabricated by electrospinning technology using a specially designed parallel spinneret. The Janus nanofiber consists of two strands of nanofibers assembled side-by-side, one strand nanofiber has tuned magnetism and the other one possesses color-tunable photoluminescence. The Janus nanofibers possess superior magnetic and luminescent properties due to their special nanostructure. Tunable colors from bluish green to orange can be realized in the flexible Janus nanofibers by varying the content of Eu(BA) 3 phen complex, and furthermore, white-lightemitting flexible Janus nanofibers are achieved using rareearth complexes as luminescent centers. In particular, it is the first time to report the influence of Fe 3 O 4 nanoparticles on the fluorescent color of the magnetic-fluorescent nanomaterials. The synthesized products have potential applications in color displays, nano-bio-label materials, and anti-counterfeit materials.
