As one of the most important characterization parameters of nano powder, particle size directly affects the physical and chemical properties of the powder, and then affects the performance of the final product. Therefore, its detection technology is an important tool for industrial production and quality management, and plays an irreplaceable role in improving product quality, reducing production costs, and ensuring product safety and effectiveness. This article will start from the principle and compare three common methods for powder particle size detection: electron microscopy, laser particle size analysis, and X-ray diffraction line width method, and analyze the advantages, disadvantages, and applicability of different particle size testing methods.
The China International Nanotechnology Industrial Expo, or CHInano for short, is the most authoritative and influential event in the field of nanotechnology application industries. This prestigious conference serves as a meeting place for professionals and innovators from across the globe to showcase their latest products, findings, and technologies. With a focus on nanomaterials, nanomanufacturing, third-generation semiconductors, nanoscale imprinting, nanobiotechnology, energy and clean technology, the CHInano serves as an invaluable platform for building international exchange and collaboration within the nanotechnology industry.

In the preparation of oxide powders, specific surface area is a very important indicator, which directly affects the performance and application of the powder. However, the specific surface area is influenced by many factors, the most important of which is the preparation method. Different preparation methods can lead to differences in the size, shape, and porosity of powder particles, which in turn affect their specific surface area. Therefore, when choosing a preparation method, it is necessary to select the appropriate process based on specific application requirements.
As an important physical property of powders, specific surface area refers to the total surface area per unit mass of oxide powder. And its size is influenced by various factors. Firstly, particle size is an important factor affecting the specific surface area of powders. The smaller the particles, the larger the specific surface area. This is because the smaller the particle size, the larger the surface area of each individual particle, thereby increasing the total surface area per unit mass of powder.
Iron oxide nanoparticles are extensively studied for their use in medical applications due to their unique magnetic properties. However, one of the major concerns with the use of inorganic nanoparticles is their potential biotoxicity. Inorganic nanoparticles have a slow clearance kinetics that can pose a potential threat to their in vivo application. The clearance of nanoparticles from the body largely depends on the surface physicochemical properties rather than their size and shape.
