Highly uniform Fe3O4/SiO2 core/shell nanoparticles functionalized by phosphorescent iridium complexes (Ir) have been strategically designed and synthesized. The Fe3O4/SiO2(Ir) nanocomposite demonstrates its versatility in various applications: the magnetic core provides the capability for magnetic resonance imaging and the great enhancement of the spin-orbit coupling in the iridium complex makes it well suited for phosphorescent labeling and simultaneous singlet oxygen generation to induce apoptosis.

Magnetically separable FeO, FeO@SiO, FeO@SiO@ZnO, and FeO@SiO@ZnO-Ag composites are synthesized using hydrothermal and wet chemistry methods. The samples obtained are characterized in terms of morphology, composition, optical, and magnetic properties using TEM, SEM-EDS, XRD, FTIR, VSM, XPS, and UV-vis, and the photodegradation of Acid Blue 161 dye under UV irradiation is investigated. As a result of SEM and TEM analyses, the diameters of FeO, FeO@SiO, FeO@SiO@ZnO, and FeO@SiO@ZnO-Ag composites are determined as 210, 220, 230 and 235 nm, respectively.

Significant efforts have been dedicated to creating recyclable and efficient methods for treating waste dyes, including rhodamine B (RhB). Nevertheless, challenges such as complex operational techniques, high costs, energy consumption, and inefficacy in dye removal persist. Here, the synthesis and application of TiO/FeO/SiO for photocatalytic degradation of RhB dye pollutants have been explored.

The early monitoring and inactivation of bacteria are of crucial importance in preventing the further spread of foodborne pathogens. (), a prototypical foodborne pathogen, is widely present in the natural environment and has the capability to trigger a range of diseases at low concentrations. In this work, we designed FeO@SiO-Au core-shell-satellite nanocomposites (NCs) modified with aptamer for efficient capture, high-sensitivity surface-enhanced Raman scattering (SERS) detection, and photothermal therapy (PTT) against .

Article Synopsis
- The paper introduces a novel method using FeO@SiO@Au nanoparticles to enhance the detection of T-2 toxin through surface plasmon resonance (SPR) sensors.
- The FeO@SiO@AuNPs not only amplify SPR signals but also aid in the separation and concentration of T-2 toxin using a magnetic field.
- Results indicate a linear relationship between T-2 toxin concentration and SPR signal, achieving a detection limit of 0.57 ng/mL, suggesting improved sensitivity for biosensors in small molecule detection and disease diagnosis.

In this study, green synthesis of modified Cu(OH) nanowires by FeO@SiO core-shell nanospheres was easily performed via chemical reduction. In other words, the direct coating of Cu(OH) on FeO@SiO was successfully realized without the extra complicated procedures. Various concentrations of synthesized nanocomposites were tested on pathogenic and nosocomial bacteria.
