Nanoparticles

What Are Nanoparticles?

Nanoparticles are ultrafine particles with dimensions typically ranging from 1 to 100 nanometers. At this scale, materials begin to show size-dependent properties like enhanced reactivity, tunable optical behavior, and a dramatically increased surface-area-to-volume ratio that sets them apart from their bulk forms. Nanoparticles can be classified by composition into elemental nanoparticles such as gold, silver, and copper, single metal oxide nanoparticles like TiO₂, ZnO, and Al₂O₃, multi-element oxide nanoparticles, and compound nanoparticles including carbides, nitrides, and sulfides. Specialized categories such as magnetic nanoparticles and nanocellulose further expand the range of functional nanomaterials available for research and industry. If you are unsure which grade suits your work, our guide on how to choose the right nanoparticles can help.

How Nanoparticles Are Made

Nanoparticles are produced through both top-down and bottom-up routes, each affecting particle size, purity, and morphology. Physical methods such as inert gas condensation and chemical synthesis allow precise control over the final product, and understanding these top-down and bottom-up approaches helps in selecting the right material for a given application.

Types of Nanoparticles

• Elemental metal nanoparticles such as gold, silver, copper, and platinum
• Single metal oxide nanoparticles including titanium dioxide, zinc oxide, and aluminum oxide
• Multi-element and mixed oxide nanoparticles for advanced functional applications
• Compound nanoparticles such as carbides, nitrides, and sulfides
• Magnetic nanoparticles including iron oxide powders
• Nanocellulose as a sustainable, bio-based nanomaterial

Nanoparticle Applications

The unique properties of nanoparticles make them essential across a wide range of industries. Titanium dioxide nanoparticles are widely used in photocatalysis, UV protection, and self-cleaning coatings, with performance that often depends on the rutile or anatase crystal phase. Silver nanoparticles serve as antimicrobial agents in healthcare and textiles, one of the many applications of silver nanoparticles across sectors. Iron oxide nanoparticles enable targeted drug delivery and MRI contrast enhancement in biomedical settings. In energy storage, nanoparticles are integrated into battery electrode materials to improve charge capacity and cycling performance. Other key applications include catalysis, ceramic sintering, conductive inks, polymer reinforcement, and environmental remediation, including emerging uses in carbon capture technology.
