Why is material characterization important for nanomaterials?
When designing new materials for specific applications, it’s often crucial to control the synthetic nanoparticles’ size distribution, shape, surface properties, dispersion, and aggregation stability, as well as the material’s elemental and nanocrystalline composition.
For instance, understanding the crystal structure and hydrodynamic behavior of MOF nanoparticles is essential to ensuring that they can harvest and release ions effectively.
And, in thin-film applications, nanofilm thickness, roughness, and layer properties are also critical parameters in the production of devices employing the special properties of ‘two-dimensional’ buried layers.
Additionally, for several synthetic nanoparticle applications, potential nanotoxicity and nanosafety concerns have resulted in a growing number of nano-regulations. Characterization is required to ensure that these regulations are met.
What are our nanoparticle analysis solutions?
At Malvern Panalytical, we offer a wide range of solutions to support research and development in nanoscience and nanotechnology:
- Techniques such as dynamic light scattering (DLS), electrophoretic light scattering (ELS), and laser diffraction (LD) enable researchers to determine and verify the dimensions and behaviors of nanoparticles in liquids.
- X-ray scattering: Small-angle X-ray scattering (SAXS) and wide-angle X-ray scattering (WAXS) combine information about nanoparticle shape and size with crystal structure analysis of any nano-crystals present.
- High-resolution X-ray diffraction (HR-XRD) and X-ray reflectometry (XRR) are used to investigate ‘two-dimensional’ nano-layers.
- Our X-ray fluorescence (XRF) spectrometers can analyze nanoparticles’ elemental composition, enabling the assessment of parameters such as the concentration of doping agents, or impurities.
- Nanoparticle tracking analysis can also be used as a tool in nanotoxicological studies, for nanoparticle concentration determination, or to investigate whether a given sample can be classified as a nanomaterial.
