Nanomaterials
Nanomaterials
Nanomaterials are defined as materials possessing, at minimum, one external dimension measuring 1-100 nm. Nanomaterials can occur naturally, created as the by-products of combustion reactions or produced purposefully through engineering to perform a specialized function. These materials can have different physical and chemical properties as compared to their bulk-form counterparts.
The properties of nanomaterials, particularly their size, offer various advantages and versatility to be tailored for specific requirements that accentuate their usefulness. An additional advantage is their high porosity, which increases demand for their use in a multitude of industries including healthcare, cosmetics, environmental preservation and air purification. The physical and chemical properties of nanoparticles are extremely important to their performance. The key parameters of nanoparticles’ physical characterization include size, shape, surface and morphology.
Zeta potential is one of the important physical related to the long-term stability of the nanoparticles in solution and suspension. The chemical composition and the intrinsic toxicological properties of the chemical are important.
Measurement Types
Particle Size Distribution
Particle size analysis in the range 0.01-3500 microns. For nanoparticle analysis see dedicated section.
Morphology
Morphological analysis of particles in the range 0.5-10000 microns (size, shape and transparency of particles). Integrated Raman chemical analysis with MDRS (Morphologically Directed Raman Spectroscopy).
Nanoparticle Characterization
Size, concentration and zeta potential anlysis of nano-systems using light scattering techniques such as DLS, ELS and NTA techniques.
Rheology, Viscosity and Powder Flowability
Viscosity measurement and visco-elastic properties characterization of liquid dispersions, complex fluids and semi-solid materials.
Stability Analysis
Rapid and objective quantification of concentrated dispersion real stability using Multiple Light Scattering.
High Pressure Homogenizing
High pressure homogenizing technique to produce stable nanoemulsions, reduce particle size or molecular weight of polysaccharides, nanoencapsulation, de-agglomeration, etc.
Exosomes and EVs Characterization
Multiparametric characterization of exosomes and EVs including Sizing, Concentration per size range, Count, Phenotyping, Cargo, Integrity, Purity, etc.
Biomolecular Interactions
Biomolecular interactions of proteins, antibodies, nucleic acids, lipids and other biomolecules using ITC Microcalorimetry or BioLayer Interferometry BLI techniques.
Protein Aggregate Analysis
SEC is the standard method for protein aggregate analysis. The choice of pore size is related to the size of the molecule to be separated.
Elemental Analysis
XRF provides both qualitative and quantitative information on a wide variety of sample types. It can quantify elements from beryllium (Be) up to americium (Am) in concentrations from 100% down to sub-ppm level.
