摘要

在这项研究中,FeCoNi 合金纳米粒子与 Nd(OH)3 纳米结构相结合,形成了独特的棉花状纳米粒子(C-NPs)。这些 C-NPs 是通过两步反应化学研磨工艺合成的。这些纳米颗粒来自于一种金属氯化物(FeCl2、CoCl2 和 NiCl2)和钠(Na)的混合物,钠在 SPEX 研磨设备中用作反应的前体。铁、钴和镍的重量百分比保持相同(1:1:1)。随后,在相同的 SPEX 研磨装置中,利用 NdCl3 和 Na 通过固态反应将 Nd(OH)3 纳米结构附着到铁钴镍纳米粒子上。通过改变钕的含量来研究其对 Nd(OH)3 与 CoNiFe 纳米粒子表面结合的影响。电子显微镜显示了棉花状纳米粒子的形成,并利用二次离子质谱鉴定了元素的分布。X 射线衍射分析验证了 CoNiFe 合金和 Nd(OH)3 相。与 BT20 细胞系(三阴性乳腺癌)培养后,透射电子显微镜图像观察到这些纳米粒子通过内吞作用被细胞内化,这可能是由于 -OH 基团与细胞膜之间的相互作用。随后,对含有 C-NPs 的细胞进行了光致发光研究,发现在 400 纳米和 486 纳米处有两个不同的发射峰。X 射线光电子能谱显示,在铁钴镍-钕(OH)3 复合物中存在各种异质结构,这些异质结构可能是产生这些发射特性的原因。

Synthesis of cotton-like FeCoNi-Nd(OH)3 nanoparticles via reactive mechanical milling: Investigating chemical properties for cellular signaling applications

In this study, FeCoNi alloy nanoparticles were combined with Nd(OH)3 nanostructures to create unique cotton-like nanoparticles (C-NPs). These C-NPs were synthesized through an accessible, two-step reactive chemical milling process. The nanoparticles originated from a blend of metal chlorides (FeCl2, CoCl2, and NiCl2) and sodium (Na), used as a precursor in the reaction, within a SPEX milling apparatus. The Fe, Co, and Ni were maintained at equal weight percentages (1:1:1). Subsequently, NdCl3 and Na were utilized to facilitate the attachment of Nd(OH)3 nanostructures onto the FeCoNi nanoparticles through a solid-state reaction in the same SPEX milling setup. The Nd content was varied to investigate its effect on the integration of Nd(OH)3 onto the surface of CoNiFe nanoparticles. Electron microscopy revealed the formation of cotton-like nanoparticles, and the distribution of elements was identified using secondary ion mass spectrometry. The CoNiFe alloy and Nd(OH)3 phases were verified by X-ray diffraction analysis. These nanoparticles were internalized into cells via endocytosis, as observed in transmission electron microscopy images after incubation with the BT20 cell line (triple-negative breast cancer), likely due to interactions between –OH groups and the cell membrane. Following this, the cells containing C-NPs underwent photoluminescence studies, revealing two distinct emission peaks at 400 nm, and 486 nm. X-ray photoelectron spectroscopy indicated the presence of various heterostructures within the FeCoNi-Nd(OH)3 complex, which may be responsible for these emission properties.

期刊介绍: The aim of Advanced Powder Technology is to meet the demand for an international journal that integrates all aspects of science and technology research on powder and particulate materials. The journal fulfills this purpose by publishing original research papers, rapid communications, reviews, and translated articles by prominent researchers worldwide. The editorial work of Advanced Powder Technology, which was founded as the International Journal of the Society of Powder Technology, Japan, is now shared by distinguished board members, who operate in a unique framework designed to respond to the increasing global demand for articles on not only powder and particles, but also on various materials produced from them. Advanced Powder Technology covers various areas, but a discussion of powder and particles is required in articles. Topics include: Production of powder and particulate materials in gases and liquids(nanoparticles, fine ceramics, pharmaceuticals, novel functional materials, etc.); Aerosol and colloidal processing; Powder and particle characterization; Dynamics and phenomena; Calculation and simulation (CFD, DEM, Monte Carlo method, population balance, etc.); Measurement and control of powder processes; Particle modification; Comminution; Powder handling and operations (storage, transport, granulation, separation, fluidization, etc.)
