“…In order to stabilize the molecular weight, the propyl ester of gallic acid—Tenox PG (purchased from Aldrich, Gillingham, Dorset, UK) as an antioxidant was applied. The modifiers of the cellulose fibers were the core/shell-type NPs: Fe 3 O 4 /SiO 2 /LnF 3 :Tb 3+ and Fe 3 O 4 /SiO 2 /LnF 3 :Eu 3+ , synthesized according to the protocol reported by Runowski and Lis 39 (synthesis details can be found in the Supporting Information).…”

“…Characteristic features of lanthanides are long (in the range of a few microseconds to milliseconds) luminescence lifetimes, photostability, and narrow bands of absorption and emission. 29−31,39−45 Depending on the dopant ions, an intense and multicolor (e.g., Tb 3+ —green, Eu 3+ —red) luminescence is provided. 30,46,47 Magnetite used as a magnetic core is the strongest magnet among ferrites and it can be easily obtained in the nanoscale.…”

“…52−54 Thanks to the combination of two or more functionalities in a single nanomaterial, core/shell-type nanostructures may offer superior properties in comparison to the simple materials, for example, simultaneous luminescent–magnetic or luminescent–plasmonic activity. 39,55−57 Because of the presence of an external shell, they can exhibit improved core stability, increased biocompatibility, higher resistance to aggressive agents, and so forth. 39,58…”

Novel luminescent–magnetic cellulose microfibers were prepared by a dry–wet spinning method with the use of N -methylmorpholine- N -oxide. The synthesized luminescent–magnetic core/shell type nanostructures, based on the lanthanide-doped fluorides and magnetite nanoparticles (NPs)—Fe 3 O 4 /SiO 2 /NH 2 /PAA/LnF 3 , were used as nanomodifiers of the fibers. Thanks to the successful incorporation of the bifunctional nanomodifiers into the cellulose structure, the functionalized fibers exhibited superior properties, that is, bright multicolor emission under UV light and strong magnetic response. By the use of the as-prepared fibers, the luminescent–magnetic thread was fabricated and used to sew and make a unique pattern in the glove material, as a proof of concept for advanced, multimodal cloths’/materials’ protection against counterfeiting. The presence and uniform distribution of the modifier NPs in the polymer matrix were confirmed by X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray analysis (EDX). The concentration of the modifier NPs in the fibers was determined by inductively coupled plasma mass spectrometry, EDX, and magnetic measurements. The luminescence characteristics of the materials were examined by photoluminescence spectroscopy, and their magnetic field-responsive behavior was investigated by a superconducting quantum interference device.

BackgroundCore–shell-structured nanoparticles (NPs) have attracted much scientific attention due to their promising potential in biomedical fields in recent years. However, their underlying mechanisms of action and potential adverse effects following administration remain unknown.MethodsIn the present study, a 1H nuclear magnetic resonance-based metabonomic strategy was applied to investigate the metabolic consequences in rats following the intravenous administration of parent NPs of core–shell-structured nanoparticles, Fe3O4@SiO2-NH2 (Fe@Si) NPs.ResultsAlterations reflected in plasma and urinary metabonomes indicated that Fe@Si NPs induced metabolic perturbation in choline, ketone-body, and amino-acid metabolism besides the common metabolic disorders in tricarboxylic acid cycle, lipids, and glycogen metabolism often induced by the exogenous agents. Additionally, intestinal flora metabolism and the urea cycle were also influenced by Fe@Si NP exposure. Time-dependent biological effects revealed obvious metabolic regression, dose-dependent biological effects implied different biochemical mechanisms between low- and high-dose Fe@Si NPs, and size-dependent biological effects provided potential windows for size optimization.ConclusionNuclear magnetic resonance-based metabonomic analysis helps in understanding the biological mechanisms of Fe@Si NPs, provides an identifiable ground for the selection of view windows, and further serves the clinical translation of Fe@Si NP-derived and -modified bioprobes or bioagents.
