Article Abstract
Photo-modulated magnetism has become an emerging method for technological applications, such as magneto-optical devices. In this work, by introducing oxygen during rapid thermal annealing, NiFe/NiFeO core/shell nanoparticles were successfully fabricated by pulsed laser deposition. Obvious photo-modulated ferromagnetism was observed in core/shell nanoparticles confined in AlO film. Theoretical and experimental investigations indicate much more photogenerated electrons are captured at the interface of NiFe/NiFeO compared with NiFe nanoparticles due to interfacial effect, resulting in the improved ferromagnetism under light irradiation. This work provides a promising strategy for optical engineering design of optical information storage, high-speed wireless communication, and magneto-optical semiconductor devices.

Electronic capacitor films based on polymer matrices and inorganic nanofillers capable of storing more energy play a crucial role in advanced modern electrical industries and devices. Herein, a series of nanocomposite films composed of "core-shell-dot" BNNs-PDA@Ag hybrid structures with multiple breakdown strength enhancement mechanisms as fillers and methyl methacrylate--glycidyl methacrylate (MG) copolymers as matrices were successfully synthesized. The introduced 2D and wide-bandgap BNNs not only enhanced the breakdown strength by taking advantage of their excellent physical properties, but also further improved their energy storage properties both at ambient and elevated temperatures through the formation of deeper traps at the organic-inorganic interface.

Background: Iron (Fe) is an essential micronutrient for plant growth, but the conventional DTPA soil analysis method for detecting available iron has notable limitations, requiring advanced instruments and lengthy preparation time. Developing a more affordable, user-friendly, and efficient method for iron detection in soil could greatly improve crop nutrition management. Here, a facile nanoscopic method was developed to quantify available Fe ions in the soil by forming a luminescence quenching complex in chelation with bathophenanthroline disulphonic acid disodium salt (Fe/BPDS complex).

Hemoperfusion is one of the most effective blood purification techniques to quickly remove bilirubin from the blood of patients with kidney or liver failure. Although numerous adsorbent materials with high adsorption capacity have been developed, their clinical application are still limited due to poor biocompatibility and biosafety issues. Herein, biocompatible core-shell structured adsorbents with cellulose microspheres (CMs) as the supporting core and phase-transformed lysozyme (PTL) as the functional shell are fabricated for the removal of bilirubin in hemoperfusion.

A dual-mode aptasensor was engineered for aflatoxin B (AFB) detection by functional integration of peroxidase-mimetic Au@CeO core-shell nanostructures with emissive carbon dots (CDs). The Au@CeO nanocomposite, synthesized via spontaneous redox reaction, exhibited enhanced peroxidase-like activity due to abundant Ce/oxygen vacancies facilitating hydroxyl radical generation. The aptasensor utilizes a competitive binding mechanism, where AFB competed with immobilized Au@CeO-CDs-Apt1 probes for binding sites, resulting in inversely proportional colorimetric and fluorescent signals.

The versatility of lanthanide-doped near-infrared (NIR, 700-1,700 nm) luminescent nanoparticles makes them valuable tools in various scientific and technological fields, from bioimaging to information security. However, the luminescence intensity of typical lanthanide-doped nanoparticles is significantly influenced by the efficiency of the sensitizer. The introduction of transition metal ions (such as Cr, Mn and Ni) can greatly enrich the library of lanthanide NIR luminescence nanoparticles.
