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.

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 homogenizer

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.

Polymer characterization

Gel permeation chromatography (GPC) that separates analytes on the basis of size, typically in organic solvents. The technique is often used for the analysis of polymers.
