NanoComposix’s nanocubes have a polyvinylpyrrolidone (PVP) surface and are available with edge lengths of 75 nm or 100 nm. The particles have very high size and shape uniformity (coefficient of variation < 8%). The cubes are provided in ethanol at a silver mass concentration of 1 mg/mL.

Due to the cubic shape, silver nanocubes have unique optical properties. Much like gold nanoshells, the nanocubes are bichromic, exhibiting different colors depending on whether the sample is transmitting or scattering incident light. When illuminated from the front, 100 nm silver nanocubes appear beige in color, while illuminating them from behind yields a vibrant purple color. This unique feature can be utilized to generate color properties rarely seen in other materials with applications in cosmetics, plasmonic paints, and for integration into artisan glass and jewelry. Additionally, because these color properties are nearly impossible to replicate using traditional dyes and other colored materials, silver nanocubes can be used to create a unique optical signature for use in brand protection and anti-counterfeiting applications.

The crystal orientation of the nanocube surface ({100}) makes the nanocubes an ideal material for facet-selective catalysis studies. The nanocubes can also be used as templates for galvanic replacement to produce Au nanocages. Other applications include using the particles as patch antennas on surfaces to precisely measure particle-surface separation distances and their use as ultrasensitive molecular detectors.

Nanocube size, surface and dispersion media can be tuned for your application. Contact us for more information on our custom fabrication capabilities.
