General description

Our silver nanoparticles (10 nm in diameter) are spherical nanoparticles of metallic silver dispersed in an aqueous buffer. The particles have high electronic conductivity, high surface area, and, because of their tightly controlled particle size, fluoresce at 388 nm with a FWHM of only 50 nm.

Application

AgNPs dispersion can be used for a variety of applications such as optoelectronics, energy harvesting, and surface enhanced Raman spectroscopy (SERS).
