Summary: A novel synthesis method was introduced to enhance the load of magnetic nanoparticles and gold nanorods in nanogels. Two different structures, simple cores and core-shell, were synthesized and their heating properties under alternating magnetic field or laser exposure were compared. The core-shell structure exhibited a higher heating capacity in both modalities.

Summary: In this study, a large-scale iron-based vdW material Fe4GeTe2 with a high Curie temperature (Tc) of around 530 K was developed and its high-temperature ferromagnetism was confirmed by multiple characterizations. Theoretical calculations indicated that the interface-induced right shift of unpaired Fe d electrons' localized states is responsible for the enhanced Tc, which was confirmed by ultraviolet photoelectron spectroscopy. Additionally, by precisely tailoring Fe concentration, arbitrary control of magnetic anisotropy between out-of-plane and in-plane was achieved without inducing any phase disorders. This finding highlights the high potential of Fe4GeTe2 in spintronics, potentially enabling the room-temperature application of all-vdW spintronic devices.

Summary: A label-free and RNA extraction-free method for detecting SARS-CoV-2 has been developed, which uses DNA as a template to form anisotropic gold nanoparticles without any chemical modification. The plasmonic biosensor based on this method can detect low concentrations of SARS-CoV-2 and has the potential for point-of-care testing.

Summary: Janus droplets were prepared by mixing three immiscible liquids - olive oil, silicone oil and water - in the presence of gold and magnetite nanoparticles. These core-shell droplets can be stimulated by an external magnetic field, leading to the controlled inner rotation of the droplets, demonstrating the potential of interfacially confined magnetic nanoparticles for manipulating complex double emulsions.

Summary: In this study, the controllable self-assembly of DNA-linked gold nanoparticles (AuNPs) for in vivo biomedical applications was achieved by using programmable DNA tetrahedral structures. Three different sizes of AuNPs (20nm, 10nm, and 5nm) were organized and positioned using this method. The density and arrangement of the satellite AuNPs around the core AuNPs were controlled by tuning the size and amount of DNA tetrahedron functionalized on the core AuNPs, resulting in strong electromagnetic field enhancement. With the conjugation of Raman molecules, strong surface-enhanced Raman scattering photoacoustic imaging signals were generated, allowing for the imaging of microRNA-21 and tumor tissues in vivo. This study provides an efficient strategy for building precision plasmonic superstructures in plasmonic-based bioanalysis and imaging.

Summary: Cartilage injury is a common problem with limited repair options. This study focuses on a hydrogel scaffold made from methacrylated gelatin (GelMA) and iron oxide nanoparticles (Fe2O3), and investigates its mechanical properties as well as its interaction with chondrocytes. The results show that the stiffness of the Fe2O3/GelMA hydrogel can be controlled by adjusting the concentration of magnetic nanoparticles, and that this hybrid hydrogel promotes cell morphology changes and metabolic activities in chondrocytes. The study also demonstrates the potential of the Fe2O3/GelMA hydrogel for tissue engineering applications.
