Nanoparticles & Nanopowders Supplier | USA Shipping

Q: Does a smaller particle size always mean better performance?

No. The choice of the preferred size is determined by the material, application, processing method, dispersion behavior, surface area, phase, and target performance. Small particles can also cause increased surface interactions and agglomeration problems.

Q: What is the difference between a primary particle, an aggregate and an agglomerate?

A primary particle is a basic unit particle. Aggregates are dense arrangements of particles while agglomerates are less dense agglomerations that may be more easily broken apart during processing. The terms used for these levels may vary in product documentation.

Q: What particle sizes are available?

Particle size varies per product. The MKnano catalog includes nanoscale, submicron and micron-scale values, with some grades reporting nanoscale grain/crystallite size along with a larger APS. Check COA and exact product specification.

What Are Nanoparticles?

Nanoparticles are particles of nanometer-scale dimensions. Health Canada’s working definition of nanomaterial includes 1-100 nm inclusively, whereas ISO 80004-1:2023 describes the nanoscale as approximately 1-100 nm. However, in commercial catalogs, product naming can also reflect nanoscale crystallites, grains, or internal structures even when the measured aggregate or average powder size is larger.

In procurement, the material name alone is not sufficient. Particle-size definition/distribution, purity, morphology, specific surface area, crystal phase, surface chemistry, and supply form can all affect processing and application behavior. Use the precise grade specification and characterization data available, instead of assuming everything in a “nanoparticles” category has the same size specification.

How to Select the Right Nanoparticle Grade

Specification	Why it matters	Buyer/engineering check
Composition/formula	Defines the material system and baseline chemistry.	Confirm formula, elemental composition, CAS where applicable, and grade identity.
Reported particle size	Can influence surface area, processing, and selected optical, electrical, magnetic, or catalytic behavior.	Confirm if the number represents primary/crystallite size, APS/D50, hydrodynamic diameter, or some other method-specific number.
Particle-size distribution	An average value may hide a broad population or large agglomerates.	Request distribution information if uniformity is important.
Purity	Impurities can affect electrical, catalytic, magnetic, and analytical work.	Check COA and available impurity info for exact grade/lot.
Morphology	Particle shape can influence packing, contact area, dispersion, and processing.	Use morphology data only where documented for that grade level.
BET specific surface area	Indicates accessible surface area and can be important in surface-driven applications.	BET is a surface area measurement, not a direct substitute for particle size measurement.
Crystal phase	Different phases of the same chemistry can have different functional behavior.	Check phase (XRD/phase info) when phase is application critical.
Surface treatment	Can affect stability, oxidation, dispersibility, and matrix compatibility.	Verify passivation, coating, ligand, or functional group and compatibility with process.
Supply form	Dry powder and liquid dispersion require different handling and formulation approaches.	Choose based on solvent/matrix compatibility, concentration, and deagglomeration ability.
Documentation	Supports procurement, lab review, and reproducibility.	Request the current SDS, COA, product spec/TDS, and any available characterization data.

Nanoparticles: How to Read Particle Size & Characterization Data?

Particle-size numbers depend on the method used and are not interchangeable. This distinction is especially important where the product has nanoscale crystallites or grains, but larger aggregates, agglomerates, or hydrodynamic diameters.

Reported data	What it usually tells you	Important limitation
Primary particle/grain/crystallite size	A small structural unit measured or estimated by a method such as TEM, SEM, or XRD analysis.	“Crystallite,” “grain,” and “primary particle” are not always interchangeable; context of process and product must be used.
APS / D50 / average powder size	A central or average size value for the measured population.	Value depends on sampling and measurement method; may contain aggregates/agglomerates.
DLS hydrodynamic diameter	Apparent particle size in a liquid, including the effect of solvation layers and dispersed clusters.	Not directly comparable to dry-powder TEM/SEM size. Larger particles may dominate intensity-weighted results.
Aggregate/agglomerate size	Size of clusters formed from smaller primary particles or crystallites.	Can be larger than the nanoscale building blocks and may change during processing.
BET specific surface area	Surface area per unit mass (m²/g).	BET does not measure particle size directly; any equivalent size estimate requires assumptions about shape, density, and porosity.
XRD phase/crystallite information	Identifies crystal phase and can support crystallite-size estimation in suitable analyses.	The crystallite size is not the same as the whole particle or agglomerate size.
SEM / TEM morphology	Direct imaging of particle shape and size at the measured field of view.	Sample preparation and image selection are important and no image should be considered as a complete distribution.

Nanoparticle Material Families

Material family	Examples	Typical research / industrial interest
Elemental nanoparticles	Ag, Cu, Ni, Au, Pt, Si	Conductive materials, catalysis, coatings, sensors and general materials research.
Single-element oxides	ZnO, TiO₂, Al₂O₃, NiO, MgO	Ceramics, coatings, catalysts, optical/electronic and energy-material research.
Metal-alloy nanopowders	Fe-Ni, Cu-Zn, Cu-Sn, Ag-Cu	Magnetic, electrical, alloy and advanced materials research.
Multi-element oxides	BaTiO₃, ITO, ferrites, mixed oxides	Electronic ceramics, magnetic systems, sensors and energy-related research.
Carbides	SiC, WC, TiC, B₄C	Wear, high-temperature, ceramic and hard-material research.
Nitrides & other compounds	AlN, TiN, Si₃N₄, MoS₂, WS₂	Thermal, electronic, coating, tribological and advanced-material research depending on chemistry.

Key Nanoscale Considerations

There are no universal nanoparticle properties. Nanoscale behavior is material- and grade-dependent. Two powders with the same formula may behave differently due to size distribution, phase, morphology, surface state, and processing history.

Surface-to-volume ratio:

As the characteristic size decreases, more atoms can be located at or near the surface, which may alter surface-driven behavior such as adsorption, reactivity, or sintering.

Particle-size effects:

Size can alter optical, electronic, magnetic, catalytic, and thermal behavior in selected material systems. The effect is not universal and must be verified for the exact chemistry and grade.

Morphology:

Shape and aspect ratio can affect packing density, interfacial contact, flow, dispersion, and functional response.

Surface chemistry:

Stability, dispersibility and matrix compatibility can be influenced by oxidation state, native oxide shells, coatings, ligands and functional groups.

Agglomeration and dispersion:

Dry nanopowders can create aggregates and agglomerates. The real particle population in a formulation can be hugely influenced by the method of dispersion, the amount of energy input and the choice of stabilizer.

Phase/crystal structure:

Different crystalline phases of the same composition can have different properties; check phase data where it is application-critical.

Applications of Nanoparticles

Nanoparticles and nanopowders are used for energy storage, catalysis, electronics, coatings, ceramics, composites, sensing, and advanced materials research.

Their suitability will depend upon their very specific chemistry, grade, processing route, and operational conditions. Application examples do represent actual performance results.

Energy Storage & Battery Research:

Grades of nanoparticles and nanopowders are evaluated within electrode materials, conductive networks, ceramic electrolytes, and the broader context of energy storage research. Your choice will be based upon the chemistry, phase, particle size, surface area, purity, and method of formulating them all together.

Catalysis and Photocatalysis:

Reaction behavior may be affected by a particle's surface area, composition, and the actual chemistry occurring on its surfaces - so particular metal, oxide and compound nanoparticles are under study as either catalysts themselves or catalyst supports.

Conductive Materials and Electronics:

Elemental metals, conductive oxides and select compounds are researched for conductive inks, electronic materials, sensors and functionally active coatings themselves.

Surface Engineering and Coatings:

Nanopowders can be put through their paces in a variety of protective, optical, wear-resistant, conductive or other types of functional coating systems. Compatibility with the matrix and how well they disperse are really the key considerations here.

Advanced Composites and Ceramics:

Oxide, carbide and nitride nanopowders feature heavily in both ceramic and composite R&D where factors like particle size, phase, purity, sintering behaviour and the all-important interfacial compatibility hold real significance.

Sensors and Advanced Materials R&D:

Nanoparticles find application in exploratory materials research, sensing applications, magnetic systems, optical materials and many other areas too - where what's happening on the nanoscale actually influences the whole functional response.

Nanoparticles vs Nanopowders vs Dispersions vs Micron Powders

Parameters	Practical meaning for buyers
Nanoparticle	A particle related to the nanoscale; definitions vary between technical and regulatory contexts.
Nanopowder	A bulk powder comprising nanoscale particles/crystallites and often aggregates or agglomerates.
Nanoparticle dispersion	Particles supplied in a liquid medium for liquid-phase processing or to reduce handling of dry powder.
Monodisperse nanoparticle	A particle population designed or characterized to have a relatively narrow size distribution.
Submicron powder	A powder with particle sizes characteristically below about 1 µm but not necessarily in a strict 1-100 nm range.
Micron powder	A powder mainly characterized in the micrometer range.

Technical Documentation & Quality Information

For your technical purchasing needs, don't substitute category-level descriptions with product-specific details themselves. Review or request the following information for that particular grade, and if applicable, that particular lot too.

Document/data point	Purpose
Safety Data Sheet (SDS)	Hazard communication, handling and storage, exposure controls, and transportation information for the identified product.
Certificate of Analysis (COA)	Lot-specific reported results and specifications where provided.
Product specification / TDS	Grade-level composition, size, purity, physical properties and typical/target values where available.
Chemical formula, composition, CAS number	Material identity and procurement verification.
Reported size + measurement method	Clarifies whether the value is APS, D50, TEM/SEM size, DLS hydrodynamic diameter, crystallite size or another metric.
Particle-size distribution	Helps evaluate uniformity and larger-particle/agglomerate populations.
Purity/impurity information	Important for contamination-sensitive and analytical work.
BET specific surface area	Relevant to selected catalysis, adsorption, electrochemistry, and sintering applications.
Morphology / SEM or TEM data	Supports evaluation of shape and particle structure where available.
Crystal phase / XRD	Important for phase-sensitive material systems.
Surface treatment/functionalization	Supports compatibility and formulation decisions.
Packaging/quantity/lead time	Procurement and scale-up planning.

Document priority
Current product-specific documentation, labels, SDS, TDS/product specifications, COA and any agreed written specification should take precedence over category-level guidance within their stated scope. This is consistent with MKnano’s Technical Information and Use Disclaimer.

Nanoparticle Handling & Safety

Handling requirements depend on the specific chemistry, particle form, quantity, process and route of exposure. Review the current product SDS and complete a workplace- or process-specific risk assessment prior to handling. Use the hierarchy of controls, starting with elimination or substitution where possible, then appropriate engineering controls and work practices, and finally appropriate personal protective equipment as required by the material and task.

Containment or local exhaust ventilation may be appropriate where dry powders can become airborne, depending on the operation. Do not assume that one hood, glove box, respirator or glove specification is suitable for all nanomaterials. U.S. buyers can refer to NIOSH nanotechnology guidance; Canadian buyers can refer to current CCOHS nanotechnology guidance along with applicable workplace requirements.
