Nanoparticle Size & Distribution Testing

The testing of nanoparticle size and distribution is critical in industries ranging from pharmaceuticals to electronics. Nanoparticles, with diameters typically between 1 and 100 nanometers, exhibit unique physical and chemical properties that make them essential for various applications.

Understanding the size and distribution of nanoparticles can significantly impact their behavior in biological systems or industrial processes. For instance, in drug delivery, the particle size directly influences solubility, dispersion stability, and biodistribution within a target organism. In electronics, the precise control over nanoparticle dimensions is crucial for optimizing performance parameters such as conductivity.

Given these implications, accurate determination of nanoparticle size and distribution is paramount. This service involves sophisticated techniques that can provide detailed insights into the characteristics of nanoparticles. The methodologies used include dynamic light scattering (DLS), transmission electron microscopy (TEM), and laser diffraction spectroscopy (LDS). Each technique offers distinct advantages depending on the desired resolution, sample homogeneity, and the nature of the particles being analyzed.

Dynamic Light Scattering (DLS) is particularly adept at measuring particle size in suspensions, offering high-resolution measurements down to sub-nanometer scales. Transmission Electron Microscopy provides ultra-high resolution images that can reveal detailed structural information about nanoparticles. Laser Diffraction Spectroscopy offers a balance between precision and throughput, making it suitable for rapid screening across large sample sets.

The acceptance criteria for nanoparticle size and distribution testing vary based on the intended application of the particles. For pharmaceuticals, stringent standards like ISO 22410:2017 specify the acceptable ranges to ensure safety and efficacy. In electronics, compliance with IEC standards ensures interoperability and reliability.

Before conducting these tests, proper sample preparation is crucial. This includes dispersion of particles in a suitable solvent or medium to prevent aggregation, which could lead to misleading results. The choice of solvent can significantly affect the outcome, so it must be carefully selected based on the particle type and desired measurement parameters.
