Gold (Au) Microspheres

A spherical gold (Au) microparticle is attached by a polymer adhesive to the free end of a tipless AFM cantilever.

Au microspheres with diameters A = 1.5 - 3 µm, B = 3 - 5.5 µm and C = 5.5 - 9 µm are available.

NB: Please note that state-of-the-art synthesis of gold microparticles does not guarantee ideal surface smoothness and ideal spherical shape. Some nanoroughness and small shape deviations are an inevitable result of the nature of the synthesis process.
