Controlling nano color and shape with pH adjustments

Abstract:
Scientists have recently discovered that the shape, color, and optical properties of silver nanoparticles can be controlled using a method that is easy, inexpensive and takes just minutes. Simply by adjusting the pH value of the nanoparticles' immersion solution, silver nanoprisms can be transformed into nanodiscs, which can also enhance the unique light scattering properties of the particles for possible applications.
