TL;DR: MnO NPs exhibit an intrinsic SOD-like activity, which is higher than that of the native Mn-dependent SOD, making them responsive MRI contrast agents for the treatment and imaging of cancer cells with reduced SOD levels.

TL;DR: Gly-Cu(OH)2 NPs efficiently removed ROS from smoke, thereby protecting lung cancer cell lines from cytotoxic effects and making them a powerful tool for a wide range of applications in environmental chemistry, biotechnology and medicine.

Abstract: Compared to conventional deposition techniques for the epitaxial growth of metal oxide structures on a bulk metal substrate, wet-chemical synthesis based on a dispersible template offers advantages such as low cost, high throughput, and the capability to prepare metal/metal oxide nanostructures with controllable size and morphology. However, the synthesis of such organized multicomponent architectures is difficult because the size and morphology of the components are dictated by the interplay of interfacial strain and facet-specific reactivity. Here we show that solution-processable two-dimensional Pd nanotetrahedra and nanoplates can be used to direct the epitaxial growth of γ-Fe2O3 nanorods. The interfacial strain at the Pd−γ-Fe2O3 interface is minimized by the formation of an FexPd “buffer phase” facilitating the growth of the nanorods. The γ-Fe2O3 nanorods show a (111) orientation on the Pd(111) surface. Importantly, the Pd@γ-Fe2O3 hybrid nanomaterials exhibit enhanced peroxidase activity compared to ...

TL;DR: It is shown that ZnO NP can exert cytotoxic effects on several human tumor cell lines and further studies are suggested to explore the potential of ZNO NP as an innovative anti-tumor agent.

TL;DR: An (in situ) proton nuclear magnetic resonance (1H NMR) study on the ligand exchange of oleylamine by 1-octadecanethiol as a function of the particle size and repeated functionalization on Au NPs reveals that moieties closer to the NP surface are characterized by a broader diffusion coefficient distribution as well as slower diffusion.
