ISO 18115 Nanoparticle Size and Morphology Characterization by AFM
The ISO 18115 standard for characterization of nanomaterials specifically addresses the need to assess nanoparticle size distribution and morphology accurately. This service utilizes Atomic Force Microscopy (AFM) as a key tool in this process, providing precise and reliable measurements that are critical for ensuring product quality, compliance with regulatory requirements, and consistency across manufacturing batches.
AFM is particularly suited for nanoscale analysis because it can operate both in air and under liquid environments. This versatility allows us to tailor the testing conditions to suit the specific properties of your nanoparticles. The technique works by scanning a very sharp tip over the surface of the sample, measuring forces as the tip moves across each point on the surface. These measurements generate topographical images that reveal not only size but also shape and orientation details.
For nanoparticle testing, AFM is especially useful because it provides high-resolution imaging with a resolution down to atomic scale. This level of detail is crucial for understanding how nanoparticles behave in various environmental conditions, which can influence their performance and safety. The service covers the entire process from sample preparation to final analysis, ensuring that every step adheres strictly to ISO 18115 guidelines.
Sample preparation involves dispersing the nanoparticles into a suitable medium that allows for even distribution on the substrate used in AFM. This ensures accurate measurement of individual particles without agglomeration or clustering effects. The choice of dispersion medium depends on the type of nanoparticle and its intended application, but it is typically either air or water-based depending on the sample.
The process begins with a thorough cleaning and preparation of the AFM tip to ensure accurate readings. Once the nanoparticles are dispersed onto the substrate, they are imaged using high-resolution imaging modes such as contact mode, tapping mode, or oscillatory mode, depending on the specific requirements of the test. Contact mode is generally used for softer samples, while tapping mode provides higher resolution images.
AFM can also be used in liquid environments to study nanoparticle behavior under different conditions, which is essential for applications like drug delivery systems where particle stability and interaction with biological fluids are critical factors. This capability makes AFM an indispensable tool in the characterization of nanomaterials, ensuring that every aspect of particle size distribution and morphology is captured accurately.
