Fe3O4@ZIF-8: magnetically recoverable catalysts by loading Fe3O4 nanoparticles inside a zinc imidazolate framework.
A simple methodology for encapsulating ca. 10 nm-sized superparamagnetic Fe3O4 nanoparticles in zeolitic imidazolate frameworks (ZIF-8) crystals was developed. The corresponding Fe3O4@ZIF-8 heterostructured material exhibits bifunctional properties with both high magnetization (Fe3O4) and high thermal stability, large specific surface, and catalytic properties (ZIF-8). The Fe3O4@ZIF-8 catalyst ...
متن کاملMagnetically-driven selective synthesis of Au clusters on Fe3O4 nanoparticles.
A novel procedure to direct the local synthesis of gold clusters on Fe(3)O(4) nanocrystals by means of alternating magnetic fields (AMFs) is demonstrated. This process allows growing gold selectively onto the heated magnetite surface, while keeping the synthesis solution comparatively cold. Sequential AMF cycles allowed fine-tuning the amount of gold on the magnetite surfaces.
متن کاملThe Effect of Magnetic Fe3O4 Nanoparticles on the Growth of Genetically Manipulated Bacterium, Pseudomonas aeruginosa (PTSOX4)
Background: Magnetite (Fe3O4) nanoparticles are currently one of the important and acceptable magnetic nanoparticles for biomedical applications. To use magnetite nanoparticles for bacteria cell separation, the surface of nanoparticles would be modified for immobilizing of nanoparticles on the surface of bacteria. Functionalization of magnetite nanoparticles is performed by different s...
متن کاملSmart MoS2/Fe3O4 Nanotheranostic for Magnetically Targeted Photothermal Therapy Guided by Magnetic Resonance/Photoacoustic Imaging
The ability to selectively destroy cancer cells while sparing normal tissue is highly desirable during the cancer therapy. Here, magnetic targeted photothermal therapy was demonstrated by the integration of MoS2 (MS) flakes and Fe3O4 (IO) nanoparticles (NPs), where MoS2 converted near-infrared (NIR) light into heat and Fe3O4 NPs served as target moiety directed by external magnetic field to tum...
متن کاملStability and magnetically induced heating behavior of lipid-coated Fe3O4 nanoparticles
Magnetic nanoparticles that are currently explored for various biomedical applications exhibit a high propensity to minimize total surface energy through aggregation. This study introduces a unique, thermoresponsive nanocomposite design demonstrating substantial colloidal stability of superparamagnetic Fe3O4 nanoparticles (SPIONs) due to a surface-immobilized lipid layer. Lipid coating was acco...
