Copper nanoparticles (10-30 nm, 99.9% metals basis) exhibit enhanced properties compared to bulk copper due to their nanoscale size, including higher surface area and reactivity. They are widely used in electrical wiring and electronics for improved conductivity in conductive inks and pastes. As a key component in motors, transformers, and generators, nano-copper enhances performance in advanced materials.

In construction, copper nanoparticles are incorporated into coatings and composites for plumbing and roofing, providing superior corrosion resistance and durability. Their high thermal conductivity makes them ideal for heat exchangers and cooling systems in electronics.

Copper nanoparticles are employed in agriculture as fungicides and in water treatment to control algae, with improved efficacy due to nanoscale delivery. They are also used in alloys like brass and bronze for manufacturing industrial machinery, tools, and decorative items.

Due to their strong antimicrobial properties, copper nanoparticles are suitable for healthcare settings, such as antimicrobial coatings on touch surfaces in hospitals to reduce infection spread. Additional applications include catalysis, sensors, and biomedical uses like drug delivery and cancer therapy.
